EMISSION CONTROL INFORMATION
To protect the environment in which we all live, Kawasaki has incorporated crankcase emis-
sion (1) and exhaust emission (2) control systems in compliance with applicable regulations of
the United States Environmental Protection Agency and California Air Resources Board. Addi-
tionally, Kawasaki has incorporated an evaporative emission control system (3) in compliance
with applicable regulations of the California Air Resources Board on vehicles sold in California
only.
1. Crankcase Emission Control System
This system eliminates the release of crankcase vapors into the atmosphere. Instead, the vapors
are routed through an oil separator to the intake side of the engine. While the engine is operating,
the vapors are drawn into combustion chamber, where they are burned along with the fuel and air
supplied by the fuel injection system.
2. Exhaust Emission Control System
This system reduces the amount of pollutants discharged into the atmosphere by the exhaust
of this motorcycle. The fuel, ignition, and exhaust systems of this motorcycle have been carefully
designed and constructed to ensure an efficient engine with low exhaust pollutant levels.
The exhaust system of this model motorcycle manufactured primarily for sale in California in-
cludes a catalytic converter system.
3. Evaporative Emission Control System
Vapors caused by fuel evaporation in the fuel system are not vented into the atmosphere. In-
stead, fuel vapors are routed into the running engine to be burned, or stored in a canister when
the engine is stopped. Liquid fuel is caught by a vapor separator and returned to the fuel tank.
The Clean Air Act, which is the Federal law covering motor vehicle pollution, contains what is
commonly referred to as the Act’s “tampering provisions”.
“Sec. 203(a) The following acts and the causing thereof are prohibited.
(3)(A) for any person to remove or render inoperative any device or element of design installed
on or in a motor vehicle or motor vehicle engine in compliance with regulations under this
title prior to its sale and delivery to the ultimate purchaser, or for any manufacturer or dealer
knowingly to remove or render inoperative any such device or element of design after such
sale and delivery to the ultimate purchaser.
(3)(B) for any person engaged in the business of repairing, servicing, selling, leasing, or trading
motor vehicles or motor vehicle engines, or who operates a fleet of motor vehicles know-
ingly to remove or render inoperative any device or element of design installed on or in a
motor vehicle or motor vehicle engine in compliance with regulations under this title follow-
ing its sale and delivery to the ultimate purchaser...”
NOTE
○
The phrase “remove or render inoperative any device or element of design” has been generally
interpreted as follows.
1. Tampering does not include the temporary removal or rendering inoperative of de-
vices or elements of design in order to perform maintenance.
2. Tampering could include.
a.Maladjustment of vehicle components such that the emission standards are ex-
ceeded.
b.Use of replacement parts or accessories which adversely affect the performance
or durability of the motorcycle.
c.Addition of components or accessories that result in the vehicle exceeding the stan-
dards.
d.Permanently removing, disconnecting, or rendering inoperative any component or
element of design of the emission control systems.
WE RECOMMEND THAT ALL DEALERS OBSERVE THESE PROVISIONS OF FEDERAL
LAW, THE VIOLATION OF WHICH IS PUNISHABLE BY CIVIL PENALTIES NOT EXCEEDING
$10 000 PER VIOLATION.

TAMPERING WITH NOISE CONTROL SYSTEM PROHIBITED
Federal law prohibits the following acts or the causing thereof. (1) The removal or rendering
inoperative by any person other than for purposes of maintenance, repair, or replacement, of any
device or element of design incorporated into any new vehicle for the purpose of noise control
prior to its sale or delivery to the ultimate purchaser or while it is in use, or (2) the use of the
vehicle after such device or element of design has been removed or rendered inoperative by
any person.
Among those acts presumed to constitute tampering are the acts listed below.
•
Replacement of the original exhaust system or muffler with a component not in compliance
with Federal regulations.
•
Removal of the muffler(s) or any internal portion of the muffler(s).
•
Removal of the air box or air box cover.
•
Modifications to the muffler(s) or air intake system by cutting, drilling, or other means if such
modifications result in increased noise levels.

1-2 GENERAL INFORMATION
Before Servicing
Before starting to perform an inspection service or carry out a disassembly and reassembly opera-
tion on a motorcycle, read the precautions given below. To facilitate actual operations, notes, illustra-
tions, photographs, cautions, and detailed descriptions have been included in each chapter wherever
necessary. This section explains the items that require particular attention during the removal and
reinstallation or disassembly and reassembly of general parts.
Especially note the following.
Battery Ground
Before completing any service on the motorcycle, discon-
nect the battery cables from the battery to prevent the en-
gine from accidentally turning over. Disconnect the ground
cable (–) first and then the positive (+). When completed
with the service, first connect the positive (+) cable to the
positive (+) terminal of the battery then the negative (–) ca-
ble to the negative terminal.
Edges of Parts
Lift large or heavy parts wearing gloves to prevent injury
from possible sharp edges on the parts.
Solvent
Use a high flash-point solvent when cleaning parts. High
flash-point solvent should be used according to directions
of the solvent manufacturer.
Cleaning Vehicle before Disassembly
Clean the vehicle thoroughly before disassembly. Dirt or
other foreign materials entering into sealed areas during ve-
hicle disassembly can cause excessive wear and decrease
performance of the vehicle.

GENERAL INFORMATION 1-3
Before Servicing
Arrangement and Cleaning of Removed Parts
Disassembled parts are easy to confuse. Arrange the
parts according to the order the parts were disassembled
and clean the parts in order prior to assembly.
Storage of Removed Parts
After all the parts including subassembly parts have been
cleaned, store the parts in a clean area. Put a clean cloth
or plastic sheet over the parts to protect from any foreign
materials that may collect before re-assembly.
Inspection
Reuse of worn or damaged parts may lead to serious ac-
cident. Visually inspect removed parts for corrosion, discol-
oration, or other damage. Refer to the appropriate sections
of this manual for service limits on individual parts. Replace
the parts if any damage has been found or if the part is be-
yond its service limit.
Replacement Parts
Replacement parts must be KAWASAKI genuine or
recommended by KAWASAKI. Gaskets, O-rings, oil seals,
grease seals, circlips, cotter pins or self-locking nuts must
be replaced with new ones whenever disassembled.
Assembly Order
In most cases assembly order is the reverse of disassem-
bly, however, if assembly order is provided in this Service
Manual, follow the procedures given.

1-4 GENERAL INFORMATION
Before Servicing
Tightening Sequence
Generally, when installing a part with several bolts, nuts,
or screws, start them all in their holes and tighten them to
a snug fit. Then tighten them according to the specified se-
quence to prevent case warpage or deformation which can
lead to malfunction. Conversely when loosening the bolts,
nuts, or screws, first loosen all of them by about a quar-
ter turn and then remove them. If the specified tightening
sequence is not indicated, tighten the fasteners alternating
diagonally.
Tightening Torque
Incorrect torque applied to a bolt, nut, or screw may
lead to serious damage. Tighten fasteners to the specified
torque using a good quality torque wrench.
Force
Use common sense during disassembly and assembly,
excessive force can cause expensive or hard to repair dam-
age. When necessary, remove screws that have a non
-permanent locking agent applied using an impact driver.
Use a plastic-faced mallet whenever tapping is necessary.
Gasket, O-ring
Hardening, shrinkage, or damage of both gaskets and
O-rings after disassembly can reduce sealing performance.
Remove old gaskets and clean the sealing surfaces thor-
oughly so that no gasket material or other material remains.
Install the new gaskets and replace the used O-rings when
re-assembling.
Liquid Gasket, Non-permanent Locking Agent
For applications that require Liquid Gasket or a
Non-permanent Locking Agent, clean the surfaces so
that no oil residue remains before applying liquid gasket or
non-permanent locking agent. Do not apply them exces-
sively. Excessive application can clog oil passages and
cause serious damage.

GENERAL INFORMATION 1-5
Before Servicing
Press
For items such as bearings or oil seals that must be
pressed into place, apply small amount of oil to the con-
tact area. Be sure to maintain proper alignment and use
smooth movements when installing.
Ball Bearing and Needle Bearing
Do not remove pressed ball or needle unless removal is
absolutely necessary. Replace with new ones whenever
removed. Press bearings with the manufacturer and size
marks facing out. Press the bearing into place by putting
pressure on the correct bearing race as shown.
Pressing the incorrect race can cause pressure between
the inner and outer race and result in bearing damage.
Oil Seal, Grease Seal
Do not remove pressed oil or grease seals unless removal
is necessary. Replace with new ones whenever removed.
Press new oil seals with manufacture and size marks facing
out. Make sure the seal is aligned properly when installing.
Apply specified grease to the lip of seal before installing
the seal.
Circlips, Cotter Pins
Replace the circlips or cotter pins that were removed with
new ones. Take care not to open the clip excessively when
installing to prevent deformation.

1-6 GENERAL INFORMATION
Before Servicing
Lubrication
It is important to lubricate rotating or sliding parts during
assembly to minimize wear during initial operation. Lubri-
cation points are called out throughout this manual, apply
the specific oil or grease as specified.
Direction of Engine Rotation
When rotating the crankshaft by hand, the free play
amount of rotating direction will affect the adjustment. Ro-
tate the crankshaft to positive direction (clockwise viewed
from output side).
Electrical Wires
A two-color wire is identified first by the primary color and
then the stripe color. Unless instructed otherwise, electrical
wires must be connected to those of the same color.
Instrument
Use a meter that has enough accuracy for an accurate
measurement. Read the manufacture’s instructions thor-
oughly before using the meter. Incorrect values may lead
to improper adjustments.

Periodic Maintenance Procedures
Fuel System (DFI)
Throttle Control System Inspection
•
Check that the throttle grip [A] moves smoothly from full
open to close, and the throttle closes quickly and com-
pletely by the return spring in all steering positions.
If the throttle grip does not return properly, check the throt-
tle cable routing, grip free play, and cable damage. Then
lubricate the throttle cable.
•
Check the throttle grip free play [B].
Throttle Grip Free Play
Standard: 2
∼ 3 mm (0.08 ∼ 0.12 in.)
If the free play is incorrect, adjust the throttle cable as
follows.
•
Loosen the locknuts [A] [B].
•
Screw both throttle cable adjusters [C] [D] to give the
throttle grip plenty of play.
•
Turn the decelerator cable adjuster [C] until 2 ∼ 3mm
(0.08 ∼ 0.12 in.) of throttle grip play is obtained.
•
Tighten the locknut [A].
•
Turn the accelerator cable adjuster [D] until 2 ∼ 3mm
(0.08 ∼ 0.12 in.) of throttle grip play is obtained.
•
Tighten the locknut [B].
If the free play can not be adjusted with the adjusters,
replace the cable.
Engine Vacuum Synchronization Inspection
NOTE
○
These procedures are explained on the assumption that
the intake and exhaust systems of the engine are in
good condition.
•
Situate the motorcycle so that it is vertical.
•
Remove the air cleaner housing (see Air Cleaner Housing
Removal in the Fuel System (DFI) chapter).
•
Pull off the rubber caps [A] and vacuum hose [B] from the
fittings of each throttle body.
•
For the CAL, SEA-B1 and TH Models, pull off the vacuum
hose [A].

2-16 PERIODIC MAINTENANCE
Periodic Maintenance Procedures
•
Plug the vacuum hose end [A].
•
Connect a vacuum gauge (special tool) and hoses [A] to
the fittings on the throttle body.
Special Tool - Vacuum Gauge: 57001-1369
•
Connect a highly accurate tachometer [B] to one of the
stick coil primary leads.
•
Plug the air switching valve hose end [A] and air cleaner
housing fitting [B].
•
Install the air cleaner housing (see Air Cleaner Housing
Installation in the Fuel System (DFI) chapter).
•
Remove the fuel hose (see Fuel Tank Removal in the Fuel
System (DFI) chapter).
•
Connect the following parts temporary.
Fuel Pump Lead Connector [A]
Fuel Hose [B]
Special Tool - Fuel Hose: 57001-1607

PERIODIC MAINTENANCE 2-17
Periodic Maintenance Procedures
•
Start the engine and warm it up thoroughly.
•
Check the idle speed, using a highly accurate tachometer
[A].
Idle Speed
Standard: 1 100 ±50 r/min (rpm)
If the idle speed is out of the specified range, adjust it with
the adjusting screw (see Idle Speed Adjustment).
NOTICE
Do not measure the idle speed by the tachometer of
the meter unit.
•
While idling the engine, inspect the throttle body vacuum,
using the vacuum gauge [B].
Throttle Body Vacuum
Standard: 40.7 ±1.3 kPa (305 ±10 mmHg) at idle speed
If any vacuum is not within specifications, first synchro-
nize the balance of the left (#1, #2 throttle valves) and
right (#3, #4 throttle valves) assemblies.
Example:

Cooling System
Coolant Level Inspection
NOTE
○
Check the level when the engine is cold (room or ambi-
ent temperature).
•
Clear the clutch cable [A] from the clamp [B].
•
Check the coolant level in the reserve tank [C] with the
motorcycle held perpendicular (Do not use the side-
stand.).
If the coolant level is lower than the “L” level line [D], un-
screw the reserve tank cap and add coolant to the “F”
level line [E].
“L”: low
“F”: full
NOTICE
For refilling, add the specified mixture of coolant
and soft water. Adding water alone dilutes the
coolant and degrades its anticorrosion properties.
The diluted coolant can attack the aluminum en-
gine parts. In an emergency, soft water alone can
be added. But the diluted coolant must be returned
to the correct mixture ratio within a few days.
If coolant must be added often or the reservoir tank
has run completely dry, there is probably leakage in
the cooling system. Check the system for leaks.
Coolant ruins painted surfaces. Immediately wash
away any coolant that spills on the frame, engine,
wheels or other painted parts.
Radiator Hose and Pipe Inspection (coolant leak,
damage, installation condition)
○
The high pressure inside the radiator hose can cause
coolant to leak [A] or the hose to burst if the line is not
properly maintained.
•
Visually inspect the hoses for signs of deterioration.
Squeeze the hoses. A hose should not be hard and
brittle, nor should it be soft or swollen.

Rear:
Upto180kg(397lb)
290 kPa (2.9 kgf/cm², 42 psi)
Wheel/Tire Damage Inspection
•
Remove any imbedded stones [A] or other foreign parti-
cles [B] from tread.
•
Visually inspect the tire for cracks and cuts, and replace
the tire if necessary. Swelling or high spots indicate inter-
nal damage, requiring tire replacement.
•
Visually inspect the wheel for cracks, cuts and dents dam-
age.
If any damage is found, replace the wheel if necessary.
Tire Tread Wear Inspection
As the tire tread wears down, the tire becomes more sus-
ceptible to puncture and failure. An accepted estimate is
that 90% of all tire failures occur during the last 10% of tread
life (90% worn). So it is false economy and unsafe to use
the tires until they are bald.
•
Measure the tread depth at the center of the tread with a
depth gauge [A]. Since the tire may wear unevenly, take
measurement at several places.
If any measurement is less than the service limit, replace
the tire (see Tire Removal/Installation in the Wheels/Tires
chapter).

2-60 PERIODIC MAINTENANCE
Periodic Maintenance Procedures
Brake Fluid Change
NOTE
○
The procedure to change the front brake fluid is as fol-
lows. Changing the rear brake fluid is the same as for
the front brake.
•
Level the brake fluid reservoir.
•
Remove the reservoir cap.
•
Remove the rubber cap from the bleed valve [A] on the
caliper.
•
Attach a clear plastic hose [B] to the bleed valve, and run
the other end of the hose into a container.
•
Fill the reservoir with fresh specified brake fluid.
•
Change the brake fluid.
○
Repeat this operation until fresh brake fluid comes out
from the plastic hose or the color of the fluid changes.
1. Open the bleed valve [A].
2. Apply the brake and hold it [B].
3. Close the bleed valve [C].
4. Release the brake [D].
NOTE
○
The fluid level must be checked often during the chang-
ing operation and replenished with fresh brake fluid. If
the fluid in the reservoir runs out any time during the
changing operation, the brakes will need to be bled
since air will have entered the brake line.
○
Front Brake: Repeat the above steps for the other
caliper.
•
Tighten:
Torque - Front Master Cylinder Reservoir Cap Screws: 1.5
N·m (0.15 kgf·m, 13 in·lb)
•
Follow the procedure below to install the rear brake fluid
reservoir cap correctly.
○
First, tighten the rear brake fluid reservoir cap [B] clock-
wise [C] by hand until slight resistance is felt indicating
that the cap is seated on the reservoir body, then tighten
the cap an additional 1/6 turn [D] while holding the brake
fluid reservoir body [A].
•
Tighten the bleed valve, and install the rubber cap.
Torque - Bleed Valves: 7.8 N·m (0.80 kgf·m, 69 in·lb)
•
After changing the fluid, check the brake for good braking
power, no brake drag, and no fluid leakage.
If necessary, bleed the air from the lines.

Master Cylinder Assembly
•
Before assembly, clean all parts including the master
cylinder with brake fluid or alcohol.
NOTICE
Except for the disc pads and disc, use only disc
brake fluid, isopropyl alcohol, or ethyl alcohol for
cleaning brake parts. Do not use any other fluid for
cleaning these parts. Gasoline, engine oil, or any
other petroleum distillate will cause deterioration of
the rubber parts. Oil spilled on any part will be diffi-
cult to wash off completely, and will eventually de-
teriorate the rubber used in the disc brake.
•
Apply brake fluid to the new parts and to the inner wall of
the cylinder.

DFI Servicing Precautions
DFI Servicing Precautions
There are a number of important precautions that should
be followed servicing the DFI system.
○
This DFI system is designed to be used with a 12 V sealed
battery as its power source. Do not use any other battery
except for a 12 V sealed battery as a power source.
○
Do not reverse the battery cable connections. This will
damage the ECU.
○
To prevent damage to the DFI parts, do not disconnect the
battery cables or any other electrical connections when
the ignition switch is ON, or while the engine is running.
○
Take care not to short the leads that are directly con-
nected to the battery positive (+) terminal to the chassis
ground.
○
When charging, remove the battery from the motorcycle.
This is to prevent ECU damage by excessive voltage.
○
Whenever the DFI electrical connections are to be dis-
connected, first turn off the ignition switch, and disconnect
the battery (–) terminal. Do not pull the lead, only the con-
nector. Conversely, make sure that all the DFI electrical
connections are firmly reconnected before starting the en-
gine.
○
Connect these connectors until they click [A].
○
Do not turn the ignition switch ON while any of the DFI
electrical connectors are disconnected. The ECU memo-
rizes service codes.
○
Do not spray water on the electrical parts, DFI parts, con-
nectors, leads and wiring.
○
If a transceiver is installed on the motorcycle, make sure
that the operation of the DFI system is not influenced by
electric wave radiated from the antenna. Check operation
of the system with the engine at idle. Locate the antenna
as far as possible away from the ECU.
○
When any fuel hose is disconnected, do not turn on the
ignition switch. Otherwise, the fuel pump will operate and
fuel will spout from the fuel hose.
○
Do not operate the fuel pump if the pump is completely
dry. This is to prevent pump seizure.
○
Before removing the fuel system parts, blow the outer sur-
faces of these parts clean with compressed air.
○
When any fuel hose is disconnected, fuel may spout out
by residual pressure in the fuel line. Cover the hose joint
with a piece of clean cloth to prevent fuel spillage.
○
When installing the fuel hoses, avoid sharp bending, kink-
ing, flattening or twisting, and run the fuel hoses with a
minimum of bending so that the fuel flow will not be ob-
structed.
○
Run the hoses according to Cable, Wire, and Hose Rout-
ing section in the Appendix chapter.
○
To prevent corrosion and deposits in the fuel system, do
not add to fuel any fuel antifreeze chemicals.

FUEL SYSTEM (DFI) 3-23
DFI Servicing Precautions
○
If the motorcycle is not properly handled, the high pres-
sure inside the fuel line can cause fuel to leak or the hose
to burst. Remove the fuel tank (see Fuel Tank Removal)
and check the fuel hose [A].
Replace the fuel hose if any fraying, cracks or bulges are
noticed.
○
To maintain the correct fuel/air mixture (F/A), there must
be no intake air leaks in the DFI system. Be sure to install
the oil filler plug [A] after filling the engine oil.

3-24 FUEL SYSTEM (DFI)
Troubleshooting the DFI System
The warning indicator light (LED) [A] is used for the FI
indicator, immobilizer indicator (equipped models) and oil
pressure warning indicator.
Outline
When a problem occurs with DFI system, the warning in-
dicator light (LED) [A] and FI warning symbol [B] blinks to
alert the rider. In addition, the condition of the problem is
stored in the memory of the ECU. For models equipped with
an immobilizer system, the warning indicator light (LED)
and immobilizer warning symbol [C] blinks, when a prob-
lem occurs in the system.
With the engine stopped and turned in the self-diagnosis
mode, the service code [A] is displayed on the LCD (Liquid
Crystal Display) by the number of two digits.
If the problem is with the following parts, the ECU can not
recognize these problem. Therefore, the warning indicator
light (LED), FI and/or immobilizer warning symbols do not
blinks, and service code is not displayed.

Fuel Pump Relay
Fuel Injectors
Stick Coil Secondary Wiring and Ground Wiring
ECU Main Relay
ECU Power Source Wiring and Ground Wiring

FUEL SYSTEM (DFI) 3-25
Troubleshooting the DFI System
When the service code [A] is displayed, for first ask the
rider about the conditions [B] of trouble, and then start to
determine the cause [C] of problem.
As a pre-diagnosis inspection, check the ECU for ground
and power supply, the fuel line for no fuel leaks, and for
correct pressure. The pre-diagnosis items are not indicated
by the warning indicator light (LED) and FI warning symbol.
Don’t rely solely on the DFI self-diagnosis function, use
common sense.
Even when the DFI system is operating normally, the
warning indicator light (LED) and FI warning symbol may
blink under strong electrical interference. Additional mea-
sures are not required. Turn the ignition switch OFF to stop
the indicator light and symbol.
If the warning indicator light (LED) and FI warning symbol
of the motorcycle brought in for repair still blinks, check the
service code.
When the repair has been done, the FI warning symbol
goes off. But the service codes stored in memory of the
ECU are not erased to preserve the problem history. The
problem history can be referred using the KDS (Kawasaki
Diagnostic System) when solving unstable problems.
When the motorcycle is down, the vehicle-down sensor
operates and the ECU shuts off the fuel pump relay, fuel in-
jectors and ignition system. The ignition switch is left ON. If
the starter button is pushed, the electric starter turns but the
engine does not start. When the starter button is pushed,
the warning indicator light (LED) and FI warning symbol
blink but the service code is not displayed. To start the
engine again, raise the motorcycle, turn the ignition switch
OFF, and then ON.
Much of the DFI system troubleshooting work consists
of confirming continuity of the wiring. The DFI parts are
assembled and adjusted with precision, and it is impossible
to disassemble or repair them.

3-26 FUEL SYSTEM (DFI)
Troubleshooting the DFI System
•
When checking the DFI parts, use a digital meter which
can be read two decimal place voltage or resistance.
○
The DFI part connectors [A] have seals [B], including the
ECU. When measuring the input or output voltage with the
connector joined, use the needle adapter set [C]. Insert
the needle adapter inside the seal until the needle adapter
reaches the terminal.
Special Tool - Needle Adapter Set: 57001-1457
NOTICE
Insert the needle adapter straight along the terminal
in the connector to prevent short-circuit between
terminals.
•
Make sure that measuring points are correct in the con-
nector, noting the position of the lock [D] and the lead
color before measurement. Do not reverse connections
of a digital meter.
•
Be careful not to short-circuit the leads of the DFI or elec-
trical system parts by contact between adapters.
•
Turn the ignition switch ON and measure the voltage with
the connector joined.
NOTICE
Incorrect, reverse connection or short circuit by
needle adapters could damage the DFI or electrical
system parts.
○
After measurement, remove the needle adapters and ap-
ply silicone sealant to the seals [A] of the connector [B]
for waterproofing.
Sealant - Liquid Gasket, TB1211: 56019-120
•
Always check battery condition before replacing the DFI
parts. A fully charged battery is a must for conducting
accurate tests of the DFI system.
•
Trouble may involve one or in some cases all items.
Never replace a defective part without determining what
CAUSED the problem. If the problem was caused by
some other item or items, they too must be repaired or
replaced, or the new replacement part will soon fail again.
•
Measure coil winding resistance when the DFI part is cold
(at room temperature).
•
Make sure all connectors in the circuit are clean and tight,
and examine leads for signs of burning, fraying, short,
etc. Deteriorated leads and bad connections can cause
reappearance of problems and unstable operation of the
DFI system.
If any wiring is deteriorated, replace the wiring.

FUEL SYSTEM (DFI) 3-27
Troubleshooting the DFI System
•
Pull each connector [A] apart and inspect it for corrosion,
dirt, and damage.
If the connector is corroded or dirty, clean it carefully. If it
is damaged, replace it. Connect the connectors securely.
•
Check the wiring for continuity.
○
Use the wiring diagram to find the ends of the lead which
is suspected of being a problem.
○
Connect the hand tester between the ends of the leads.
Special Tool - Hand Tester: 57001-1394
○
Set the tester to the × 1 Ω range, and read the tester.
If the tester does not read 0 Ω, the lead is defective. Re-
place the lead or the main harness or the subharness.
○
If both ends of a harness [A] are far apart, ground [B] the
one end [C], using a jumper lead [D] and check the con-
tinuity between the end [E] and the ground [F]. This en-
ables to check a long harness for continuity. If the harness
is open, repair or replace the harness.
○
When checking a harness [A] for short circuit, open one
end [B] and check the continuity between the other end
[C] and ground [D]. If there is continuity, the harness has
a short circuit to ground, and it must be repaired or re-
placed.
•
Narrow down suspicious locations by repeating the con-
tinuity tests from the ECU connectors.
If no abnormality is found in the wiring or connectors, the
DFI parts are the next likely suspects. Check the part,
starting with input and output voltages. However, there is
no way to check the ECU itself.
If an abnormality is found, replace the affected DFI part.
If no abnormality is found in the wiring, connectors, and
DFI parts, replace the ECU.

Self-Diagnosis
The warning indicator light (LED) [A] is used for the FI
indicator, immobilizer indicator (equipped models) and oil
pressure warning indicator.
Self-diagnosis Outline
The self-diagnosis system has two modes and can be
switched to another mode by operating the meter unit.
User Mode
The ECU notifies the rider of troubles in DFI system, igni-
tion system and immobilizer system by blinking the warning
indicator light (LED) [A], FI warning symbol [B] and immobi-
lizer warning symbol [C] when DFI, ignition and immobilizer
system parts are faulty, and initiates fail-safe function. In
case of serious troubles ECU stops the injection and igni-
tion operations.

FUEL SYSTEM (DFI) 3-37
Self-Diagnosis
Dealer Mode
The LCD (Liquid Crystal Display) display the service
code(s) [A] to show the problem(s) which the DFI system,
ignition system and immobilizer system has at the moment
of diagnosis.
Self-diagnosis Procedures
○
When a problem occurs with the DFI system and ignition
system, the warning indicator light (LED) [A] and FI warn-
ing symbol [B] blink.

Note:
(1) D-J Method: the DFI control method from medium to heavy engine load. When the engine
load is light like at idling or low speed, the ECU determines the injection quantity by calculating from
the throttle vacuum (intake air pressure sensor output voltage) and engine speed (crankshaft sensor
output voltage). This method is called D-J method. (2) α-N Method: As the engine speed increases,
and the engine load turns middle to heavy, the ECU determines the injection quantity by calculating
from the throttle opening (main throttle sensor output voltage) and the engine speed. This method is
called α-N method.
*: The master key exists in ZR1000DA/EA only.
**: This depends on the number of stopped cylinders.

Suppose:
Pg: Vacuum Pressure (Gauge) of Throttle Body
Pl: Local Atmospheric Pressure (Absolute) measured by
a barometer
Pv: Vacuum Pressure (Absolute) of Throttle Body
Vv: Sensor Output Voltage (V)
then
Pv = Pl – Pg
For example, suppose the following data is obtained:
Pg = 8 cmHg (Vacuum Gauge Reading)
Pl = 70 cmHg (Barometer Reading)
Vv = 3.2 V (Digital Meter Reading)
then
Pv = 70 – 8 = 62 cmHg (Absolute)
Plot this Pv (62 cmHg) at a point [1] on the chart and draw a
vertical line through the point. Then, you can get the usable
range [2] of the sensor output voltage.
Usable range = 3.08 ∼ 3.48 V
Plot Vv (3.2 V) on the vertical line. → Point [3].
Results: In the chart, Vv is within the usable range and
the sensor is normal.
If the reading is out of the usable range, replace the sen-
sor.
If the reading is within the usable range, check the ECU

COOLING SYSTEM 4-5
Coolant Flow Chart
Permanent type antifreeze is used as a coolant to protect the cooling system from rust and corro-
sion. When the engine starts, the water pump turns and the coolant circulates.
The thermostat is a wax pellet type which opens or closes with coolant temperature changes. The
thermostat continuously changes its valve opening to keep the coolant temperature at the proper level.
When coolant temperature is less than 55°C (131°F), the thermostat closes so that the coolant flow
is restricted through the air bleeder hole, causing the engine to warm up more quickly. When coolant
temperature is more than 58 ∼ 62°C (136 ∼ 144°F), the thermostat opens and the coolant flows.
When the coolant temperature goes up beyond 100°C (212°F), the radiator fan relay conducts to
operate the radiator fan. The radiator fan draws air through the radiator core when there is not suffi-
cient air flow such as at low speeds. This increases up the cooling action of the radiator. When the
coolant temperature is below 97.5°C (208°F), the fan relay opens and the radiator fan stops.
In this way, this system controls the engine temperature within narrow limits where the engine op-
erates most efficiently even if the engine load varies.
The system is pressurized by the radiator cap to suppress boiling and the resultant air bubbles
which can cause engine overheating. As the engine warms up, the coolant in the radiator and the
water jacket expands. The excess coolant flows through the radiator cap and hose to the reserve tank
to be stored there temporarily. Conversely, as the engine cools down, the coolant in the radiator and
the water jacket contracts, and the stored coolant flows back to the radiator from the reserve tank.
The radiator cap has two valves. One is a pressure valve which holds the pressure in the system
when the engine is running. When the pressure exceeds 93 ∼ 123 kPa (0.95 ∼ 1.25 kgf/cm², 13 ∼ 18
psi), the pressure valve opens and releases the pressure to the reserve tank. As soon as pressure
escapes, the valve closes, and keeps the pressure at 93 ∼ 123 kPa (0.95 ∼ 1.25 kgf/cm², 13 ∼ 18 psi).
When the engine cools down, another small valve (vacuum valve) in the cap opens. As the coolant
cools, the coolant contracts to form a vacuum in the system. The vacuum valve opens and allows the
coolant from the reserve tank to enter the radiator.

Coolant Deterioration Inspection
•
Remove the right center fairing (see Center Fairing Re-
moval in the Frame chapter).
•
Visually inspect the coolant [A] in the reserve tank.
If whitish cotton-like wafts are observed, aluminum parts
in the cooling system are corroded. If the coolant is
brown, iron or steel parts are rusting. In either case, flush
the cooling system.
If the coolant gives off an abnormal smell, check for a
cooling system leak. It may be caused by exhaust gas
leaking into the cooling system.
Coolant Level Inspection
•
Refer to the Coolant Level in the Periodic Maintenance
chapter.

moval in the Frame chapter).
•
Remove the radiator cap, and install a cooling system
pressure tester [A] on the filler neck [B].
NOTE
○
Wet the cap sealing surfaces with water or coolant to
prevent pressure leaks.
•
Build up pressure in the system carefully until the pres-
sure reaches 123 kPa (1.25 kgf/cm², 18 psi).
NOTICE
During pressure testing, do not exceed the pres-
sure for which the system is designed. The maxi-
mum pressure is 123 kPa (1.25 kgf/cm², 18 psi).
•
Watch the gauge for at least 6 seconds.
If the pressure holds steady, the system is all right.
If the pressure drops and no external source is found,
check for internal leaks. Droplets in the engine oil indicate
internal leakage. Check the cylinder head gasket and the
water pump.
•
Remove the pressure tester, replenish the coolant, and
install the radiator cap.

Cooling System Flushing
Over a period of time, the cooling system accumulates
rust, scale, and lime in the water jacket and radiator. When
this accumulation is suspected or observed, flush the cool-
ing system. If this accumulation is not removed, it will clog
up the water passage and considerable reduce the effi-
ciency of the cooling system.
•
Drain the cooling system (see Coolant Change in the Pe-
riodic Maintenance chapter).
•
Fill the cooling system with fresh water mixed with a flush-
ing compound.
NOTICE
Do not use a flushing compound which is harmful to
the aluminum engine and radiator. Carefully follow

Install the cap [A] on a cooling system pressure tester [B].
NOTE
○
Wet the cap sealing surfaces with water or coolant to
prevent pressure leaks.
•
Watching the pressure gauge, pump the pressure tester
to build up the pressure until the relief valve opens: the
gauge needle flicks downward. Stop pumping and mea-
sure leak time at once. The relief valve must open within
the specified range in the table below and the gauge hand
must remain within the same range at least 6 seconds.
Radiator Cap Relief Pressure
Standard: 93
∼ 123 kPa (0.95 ∼ 1.25 kgf/cm², 13 ∼ 18
psi)
If the cap can not hold the specified pressure or if it holds
too much pressure, replace it with a new one.

inspect the thermostat valve [A] at room temperature.
If the valve is open, replace the thermostat with a new
one.
•
To check valve opening temperature, suspend the ther-
mostat [A] in a container of water and raise the tempera-
ture of the water.
○
The thermostat must be completely submerged and must
not touch the container sides or bottom. Suspend an ac-
curate thermometer [B] in the water so that the heat sen-
sitive portions [C] are located in almost the same depth.
It must not touch the container, either.
If the measurement is out of the specified range, replace
the thermostat with a new one.

Seat Cutter Operation Care
1. This valve seat cutter is developed to grind the valve for
repair. Therefore the cutter must not be used for other
purposes than seat repair.
2. Do not drop or shock the valve seat cutter, or the dia-
mond particles may fall off.
3. Do not fail to apply engine oil to the valve seat cutter
before grinding the seat surface. Also wash off ground
particles sticking to the cutter with washing oil.
NOTE
○
Do not use a wire brush to remove the metal particles
from the cutter. It will take off the diamond particles.
4. Setting the valve seat cutter holder in position, operate
the cutter in one hand. Do not apply too much force to
the diamond portion.
NOTE
○
Prior to grinding, apply engine oil to the cutter and dur-
ing the operation, wash off any ground particles sticking
to the cutter with washing oil.
5. After use, wash it with washing oil and apply thin layer
of engine oil before storing.
Marks Stamped on the Cutter
The marks stamped on the back of the cutter [A] represent
the following.
60° ........................... Cutter angle [B]
37.5
....................... Outer diameter of cutter [C]
Operating Procedures
•
Clean the seat area carefully.
•
Coat the seat with machinist’s dye.
•
Fit a 45° cutter into the holder and slide it into the valve
guide.
•
Press down lightly on the handle and turn it right or left.
Grind the seating surface only until it is smooth.
NOTICE
Do not grind the seat too much. Overgrinding will
reduce valve clearance by sinking the valve into the
head. If the valve sinks too far into the head, it will
be impossible to adjust the clearance, and the cylin-
der head must be replaced.

5-34 ENGINE TOP END
Valves
•
Measure the outside diameter of the seating surface with
a vernier caliper.
If the outside diameter of the seating surface is too small,
repeat the 45° grind until the diameter is within the spec-
ified range.

repeat the 45° grind [A] until the diameter is within the
specified range.
Original Seating Surface [B]
NOTE
○
Remove all pittings of flaws from 45° ground surface.
○
After grinding with 45° cutter, apply thin coat of machin-
ist’s dye to seating surface. This makes seating surface
distinct and 32° and 60° grinding operation easier.
○
When the valve guide is replaced, be sure to grind with
45° cutter for centering and good contact.
If the outside diameter [A] of the seating surface is too
large, make the 32° grind described below.
If the outside diameter of the seating surface is within the
specified range, measure the seat width as described be-
low.
•
Grind the seat at a 32° angle [B] until the seat outside
diameter is within the specified range.
○
To make the 32° grind, fit a 32° cutter into the holder, and
slide it into the valve guide.
○
Turn the holder one turn at a time while pressing down
very lightly. Check the seat after each turn.
NOTICE
The 32° cutter removes material very quickly.
Check the seat outside diameter frequently to pre-
vent overgrinding.
○
After making the 32° grind, return to the seat outside di-
ameter measurement step above.
•
To measure the seat width, use a vernier caliper to mea-
sure the width of the 45° angle portion of the seat at sev-
eral places around the seat.
If the seat width is too narrow, repeat the 45° grind until
the seat is slightly too wide, and then return to the seat
outside diameter measurement step above.

ENGINE TOP END 5-35
Valves
If the seat width is too wide, make the 60° [A] grind de-
scribed below.
If the seat width is within the specified range, lap the valve
to the seat as described below.
•
Grind the seat at a 60° angle until the seat width is within
the specified range.
○
To make the 60° grind, fit 60° cutter into the holder, and
slide it into the valve guide.
○
Turn the holder, while pressing down lightly.
○
After making the 60° grind, return to the seat width mea-
surement step above.
Correct Width [B]
•
Lap the valve to the seat, once the seat width and outside
diameter are within the ranges specified above.
○
Put a little coarse grinding compound on the face of the
valve in a number of places around the valve head.
○
Spin the valve against the seat until the grinding com-
pound produces a smooth, matched surface on both the
seat and the valve.
○
Repeat the process with a fine grinding compound.
Lapper [A]
Valve Seat [B]
Valve [C]
•
The seating area should be marked about in the middle
of the valve face.
If the seat area is not in the right place on the valve, check
to be sure the valve is the correct part. If it is, it may have
been refaced too much; replace it.
•
Be sure to remove all grinding compound before assem-
bly.
•
When the engine is assembled, be sure to adjust the valve
clearance (see Valve Clearance Inspection in the Periodic

Engine Oil and Oil Filter
WARNING
Vehicle operation with insufficient, deteriorated,
or contaminated engine oil will cause accelerated
wear and may result in engine seizure, accident,
and injury. Check the oil level before each use and
change the oil and filter according to the periodic
maintenance chart.
Oil Level Inspection
•
Check that the engine oil level is between the upper [A]
and lower [B] levels in the oil level inspection window.
NOTE
○
Situate the motorcycle so that it is perpendicular to the
ground.
○
If the motorcycle has just been used, wait several min-
utes for all the oil to drain down.
○
If the oil has just been changed, start the engine and
run it for several minutes at idle speed. This fills the oil
filter with oil. Stop the engine, then wait several minutes
until the oil settles.
NOTICE
Racing the engine before the oil reaches every part
can cause engine seizure.
If the engine oil gets extremely low or if the oil
pump or oil passages clog up or otherwise do not
function properly, the warning indicator light (LED)
and oil pressure warning symbol will blink. If this
blink stays on when the engine is running above
idle speed, stop the engine immediately and find
the cause.
If the oil level is too high, remove the excess oil, using a
syringe or some other suitable device.
If the oil level is too low, add the correct amount of oil
through the oil filler opening. Use the same type and
make of oil that is already in the engine.
NOTE
○
If the engine oil type and make are unknown, use any
brand of the specified oil to top off the level in preference
to running the engine with the oil level low. Then at your
earliest convenience, change the oil completely.
Engine Oil Change
•
Refer to the Engine Oil Change in the Periodic Mainte-
nance chapter.

Oil Pressure Relief Valve Inspection
•
Check to see if the valve [A] slides smoothly when push-
ing it in with a wooden or other soft rod, and see if it comes
back to its seat by spring [B] pressure.
NOTE
○
Inspect the valve in its assembled state. Disassembly
and assembly may change the valve performance.
If any rough spots are found during above inspection,
wash the valve clean with a high flash-point solvent and
blow out any foreign particles that may be in the valve with
compressed air.
WARNING
Gasoline and low flash-point solvents can be
flammable and/or explosive and cause severe
burns. Clean the oil pressure relief valve in a
well-ventilated area, and take care that there are no
sparks or flame anywhere near the working area;
this includes any appliance with a pilot light. Do
not use gasoline or a low flash-point solvent to
clean the oil pressure relief valve.
If cleaning does not solve the problem, replace the oil
pressure relief valve as an assembly. The oil pressure
relief valve is precision made with no allowance for re-
placement of individual parts.

○
The connecting rod big end is bolted using the “plastic
region fastening method”.
○
This method precisely achieves the needed clamping
force without exceeding it unnecessarily, allowing the
use of thinner, lighter bolts further decreasing connecting
rod weight.
○
There are two types of the plastic region fastening. One is
a bolt length measurement method and other is a rotation
angle method. Observe one of the following two, but the
bolt length measurement method is preferable because
this is a more reliable way to tighten the big end nuts.
NOTICE
The connecting rod bolts are designed to stretch
when tightened. Never reuse the connecting rod
bolts. See the table below for correct bolt and nut
usage.
NOTICE
Be careful not to overtighten the nuts.
The bolts must be positioned on the seating surface
correctly to prevent the bolt heads from hitting the
crankcase.
(1) Bolt Length Measurement Method
•
Be sure to clean the bolts, nuts, and connecting rods
thoroughly with a high flash-point solvent, because the
new connecting rods, bolts, and nuts are treated with an
anti-rust solution.
WARNING
Gasoline and low flash-point solvents can be
flammable and/or explosive and cause severe
burns. Clean the bolts, nuts, and connecting rods
in a well-ventilated area, and take care that there
are no sparks or flame anywhere near the working
area; this includes any appliance with a pilot light.
Do not use gasoline or a low flash-point solvent to
clean them.
NOTICE
Immediately dry the bolts and nuts with com-
pressed air after cleaning.
Clean and dry the bolts and nuts completely.

•
Check the length of the connecting rod bolts.
If the stretch is more than the usable range, the bolt has
stretched too much. An overelongated bolt may break in
use.
(2) Rotation Angle Method
If you do not have a point micrometer, you may tighten
the nuts using the “Rotation Angle Method”.
•
Be sure to clean the bolts, nuts and connecting rods thor-
oughly with a high-flash point solvent, because the new
connecting rods, bolts and nuts are treated with an anti
-rust solution.
WARNING
Gasoline and low flash-point solvents can be

If the clearance is within the standard, no bearing replace-
ment is required.
If the clearance is between 0.035 mm (0.0014 in.) and the
service limit (0.06 mm, 0.0024 in.), replace the bearing in-
serts [A] with inserts painted blue [B]. Check insert/journal
clearance with the plastigage. The clearance may exceed
the standard slightly, but it must not be less than the min-
imum in order to avoid bearing seizure.
If the clearance exceeds the service limit, measure the
diameter of the crankshaft main journal.

Ball and Needle Bearing Replacement
NOTICE
Do not remove the ball or needle bearings unless it
is necessary. Removal may damage them.
•
Using a press or puller, remove the ball bearing and/or
needle bearings.
NOTE
○
In the absence of the above mentioned tools, satisfac-
tory results may be obtained by heating the case to ap-
proximately 93°C (200°F) max., and tapping the bearing
in or out.
NOTICE
Do not heat the case with a torch. This will warp the
case. Soak the case in oil and heat the oil.
•
Using a press and the bearing driver set [A], install the
new ball bearing until it stops at the bottom of its housing.
○
The new needle bearings must be pressed into the
crankcase so that the end is flush with the end of the
hole.
Special Tool - Bearing Driver Set: 57001-1129
Ball and Needle Bearing Wear
NOTICE
Do not remove the bearings for inspection. Re-
moval may damage them.
•
Check the ball bearings.
○
Since the ball bearings are made to extremely close toler-
ances, the wear must be judged by feel rather than mea-
surement. Clean each bearing in a high flash-point sol-
vent, dry it (do not spin the bearing while it is dry), and oil
it with engine oil.
○
Spin [A] the bearing by hand to check its condition.
If the bearing is noisy, does not spin smoothly, or has any
rough spots, replace it.
•
Check the needle bearings.
○
The rollers in a needle bearing normally wear very little,
and wear is difficult to measure. Instead of measuring,
inspect the bearing for abrasion, color change, or other
damage.
If there is any doubt as to the condition of a needle bear-
ing, replace it.
Oil Seal Inspection
•
Inspect the oil seals.
Replace it if the lips are misshapen, discolored (indicating
that the rubber has deteriorated), hardened or otherwise
damaged.

Balance Inspection
•
Remove the front and rear wheels (see Front/Rear Wheel
Removal).
•
Support the wheel so that it can be spun freely.
•
Spin the wheel lightly, and mark [A] the wheel at the top
when the wheel stops.
○
Repeat this procedure several times. If the wheel stops
of its own accord in various positions, it is well balanced.
If the wheel always stops in one position, adjust the wheel
balance (see Balance Adjustment).
Balance Adjustment
•
If the wheel always stops in one position, provisionally
attach a balance weight [A] on the rim at the marking using
adhesive tape.
•
Rotate the wheel 1/4 turn [B], and see whether or not the
wheel stops in this position. If it does, the correct balance
weight is being used.
If the wheel rotates and the weight goes up, replace the
weight with the next heavier size. If the wheel rotates and
the weight goes down, replace the weight with the next
lighter size. Repeat these steps until the wheel remains
at rest after being rotated 1/4 turn.
•
Rotate the wheel another 1/4 turn and then another 1/4
turn to see if the wheel is correctly balanced.
•
Repeat the entire procedure as many times as necessary
to achieve correct wheel balance.
•
Permanently install the balance weight.
Balance Weight Removal
•
Insert standard tip screwdrivers [A] [B] between the rib [C]
and weight [D] as shown in the figure.
•
Pry the balance weight with two screwdrivers and remove
the balance weight.
•
Discard the used balance weight.
NOTICE
Do not tap the screwdrivers. The rim could be dam-
aged.
Balance Weight Installation
•
Check if the weight portion has any play on the blade [A]
and clip [B].
If it does, discard it.
WARNING
Unbalanced wheels can create an unsafe riding
condition. If the balance weight has any play on
the rib of the rim, the blade and/or clip have been
stretched. Replace the loose balance weight. Do
not reuse used balance weight.

•
Check the tire rotation mark on the front and rear tires and
install them on the rim accordingly.
Tire Rotation Mark [A]
Rotating Direction [B]
•
Position the tire on the rim so that the valve [A] align with
the tire balance mark [B] (the chalk mark made during
removal, or the yellow paint mark on a new tire).
•
Install the tire bead over the rim flange using a suitable
commercially available tire changer.
•
Lubricate the tire beads and rim flanges with a soap and
water solution or rubber lubricant to help seat the tire
beads in the sealing surfaces of the rim while inflating the
tire.
•
Center the rim in the tire beads, and inflate the tire with
compressed air until the tire beads seat in the sealing
surfaces.
WARNING
Overinflating a tire can cause it to explode, causing
serious injury or death. Be sure to install the valve
core whenever inflating the tire, and do not inflate
the tire to more than 400 kPa (4.0 kgf/cm², 57 psi).

10-16 WHEELS/TIRES
Tires
•
Check to see that the rim lines [A] on both sides of the tire
sidewalls are parallel with the rim flanges.
If the rim flanges and tire sidewall rim lines are not parallel,
remove the valve core.
•
Lubricate the rim flanges and tire beads.
•
Install the valve core and inflate the tire again.
•
After the tire beads seat in the rim flanges, check for air
leakage.
○
Inflate the tire slightly above standard inflation.
○
Use a soap and water solution or submerge the tire, and
check for bubbles that would indicate leakage.
•
Adjust the air pressure to the specified pressure (see Air
Pressure Inspection in the Periodic Maintenance chap-
ter).
•
Install the air valve cap.
•
Adjust the wheel balance (see Balance Adjustment).
Tire Repair
Currently two types of repair for tubeless tires have come
into wide use. One type is called a temporary (external) re-
pair which can be carried out without removing the tire from
the rim, and the other type is called permanent (internal)
repair which requires tire removal. It is generally under-
stood that higher running durability is obtained by perma-
nent (internal) repairs than by temporary (external) ones.
Also, permanent (internal) repairs have the advantage of
permitting a thorough examination for secondary damage
not visible from external inspection of the tire. For these
reasons, Kawasaki does not recommend temporary (exter-
nal) repair. Only appropriate permanent (internal) repairs
are recommended. Repair methods may vary slightly from
make to make. Follow the repair methods indicated by the
manufacturer of the repair tools and materials so that safe
results can be obtained.

ings are removed, they will need to be replaced with
new ones.
•
Turn each bearing in the hub back and forth [A] while
checking for plays, roughness, or binding.
If bearing play, roughness, or binding is found, replace
the bearing.
•
Examine the bearing seal [B] for tears or leakage.
If the seal is torn or is leaking, replace the bearing.

Caliper Fluid Seal Damage Inspection
The fluid seal (piston seal) [A] is placed around the pis-
ton to maintain clearance between the pad and the disc. If
the seal is in a poor condition, it could lead the pad to wear
excessively or the brake to drag, which may cause the tem-
perature of the discs or the brake fluid to increase.
•
Replace the fluid seal if it exhibits any of the conditions
listed below.
○
Brake fluid leakage around the pad.
○
Brakes overheat.
○
Considerable difference in inner and outer pad wear.
○
Seal and piston are stuck together.
If the fluid seal is replaced, replace the dust seal [B] as
well. Also, replace all seals every other time the pads are
changed.

Calipers
Rear Caliper Holder Shaft Wear Inspection
The caliper body must slide smoothly on the caliper holder
shafts [A]. If the body does not slide smoothly, one pad will
wear more than the other, pad wear will increase, and con-
stant drag on the disc will raise brake and brake fluid tem-
perature.
•
Check to see that the caliper holder shafts are not badly
worn or stepped, and that the rubber friction boots are not
damaged.
If the rubber friction boot is damaged, replace the rubber
friction boot. To replace the friction boot, remove the pads
and the caliper bracket.
If the caliper holder shaft is damage, replace the caliper
bracket.

Refer to the Brake Fluid Change in the Periodic Mainte-
nance chapter.
Brake Line Bleeding
The brake fluid has a very low compression coefficient so
that almost all the movement of the brake lever or pedal
is transmitted directly to the caliper for braking action. Air,
however, is easily compressed. When air enters the brake
lines, brake lever or pedal movement will be partially used
in compressing the air. This will make the lever or pedal feel
spongy, and there will be a loss in braking power.
WARNING
Air in the brake lines diminish braking performance
and can cause an accident resulting in injury or
death. If the brake lever or pedal has a soft or
"spongy" feeling mushy when it is applied, there
might be air in the brake lines or the brake may be
defective. Do not operate the vehicle and service
the brake system immediately.
NOTE
○
The procedure to bleed the front brake line is as follows.
Bleeding the rear brake line is the same as for the front
brake.

BRAKES 12-27
Brake Fluid
WARNING
When working with the disc brake, observe the pre-
cautions listed below.
1. Never reuse old brake fluid.
2. Do not use fluid from a container that has been
left unsealed or that has been open for a long
time.
3. Do not mix two types and brands of fluid for use
in the brake. This lowers the brake fluid boiling
point and could cause the brake to be ineffec-
tive. It may also cause the rubber brake parts to
deteriorate.
4. Don’t leave the reservoir cap off for any length
of time to avoid moisture contamination of the
fluid.
5. Don’t change the fluid in the rain or when a
strong wind is blowing.
6. Except for the disc pads and disc, use only disc
brake fluid, isopropyl alcohol, or ethyl alcohol
for cleaning of the brake parts. Do not use any
other fluid for cleaning these parts. Gasoline,
engine oil, or any other petroleum distillate will
cause deterioration of the rubber parts. Oil
spilled on any part will be difficult to wash off
completely and will eventually deteriorate the
rubber used in the disc brake.
7. When handling the disc pads or disc, be careful
that no disc brake fluid or any oil gets on them.
Clean off any fluid or oil that inadvertently gets
on the pads or disc with a high flash-point sol-
vent. Do not use one which will leave an oily
residue. Replace the pads with new ones if they
cannot be cleaned satisfactorily.
8. Brake fluid quickly ruins painted surfaces; any
spilled fluid should be completely wiped up im-
mediately.
9. If any of the brake line fittings or the bleed valve
is opened at any time, the AIR MUST BE BLED
FROM THE BRAKE LINE.

ABS Servicing Precautions
There are a number of important precautions that should
be followed servicing the ABS system.
○
This ABS system is designed to be used with a 12 V
sealed battery as its power source. Do not use any
other battery except for a 12 V sealed battery as a power
source.
○
Do not reverse the battery cable connections. This will
damage the ABS hydraulic unit.
○
To prevent damage to the ABS parts, do not disconnect
the battery cables or any other electrical connections
when the ignition switch is ON or while the engine is
running.
○
Take care not to short the leads that are directly con-
nected to the battery positive (+) terminal to the chassis
ground.
○
Do not turn the ignition switch ON while any of the ABS
electrical connectors are disconnected. The ABS hy-
draulic unit memorizes service codes.
○
Do not spray water on the electrical parts, ABS parts, con-
nectors, leads and wiring.
○
If a transceiver is installed on the motorcycle, make sure
that the operation of the ABS system is not influenced
by electric wave radiated from the antenna. Locate the
antenna as far as possible away from the ABS hydraulic
unit.
○
Whenever the ABS electrical connections are to be dis-
connected, first turn off the ignition switch.
○
The ABS parts should never be struck sharply, as with
a hammer, or allowed to fall on a hard surface. Such a
shock to the parts can damage them.
○
The ABS parts cannot be disassembled. Even if a fault is
found, do not try to disassemble and repair the ABS parts,
replace it.
○
The ABS has many brake lines, pipes, and leads. And
the ABS cannot detect problems with the conventional
braking system (brake disc wear, unevenly worn brake
pad, and other mechanical faults). To prevent trouble,
check the brake lines and pipes for correct routing and
connection, the wiring for correct routing, and the brakes
for proper braking power. Be sure to check for fluid leak-
age, and bleed the brake line thoroughly.

12-34 BRAKES
Anti-Lock Brake System (Equipped Models)
WARNING
Air in the brake lines diminish braking performance
and can cause an accident resulting in injury or
death. If any of the brake line fittings, including the
ABS hydraulic unit joint nuts, or the bleed valve is
opened at any time, the air must be bled completely
from the brake line. If the brake lever has a soft
or "spongy" feeling mushy when it is applied, there
might be air in the brake lines or the brake may be
defective. Do not operate the vehicle and service
the brake system immediately.
NOTICE
Do not ride the motorcycle with air in the brake line,
or the ABS could malfunction.
○
The ABS indicator light (LED) [A] may light if the tire pres-
sure is incorrect, a non-recommended tire is installed, or
the wheel is deformed. If the indicator light lights, remedy
the problem and clear the service code.
WARNING
Use of non-recommended tires may cause malfunc-
tioning of ABS and can lead to extended braking
distance resulting in an accident causing serious
injury or death. Always use recommended stan-
dard tires for this motorcycle.

BRAKES 12-35
Anti-Lock Brake System (Equipped Models)
○
The ABS indicator light (LED) may come on if the engine
is run with the motorcycle on its stand and the transmis-
sion in gear. If the indicator light comes on, just turn the
ignition switch OFF, then clear service code 42, which in-
dicates a “Faulty front wheel rotation sensor”.
○
When the ABS operates, the ABS makes noise and the
rider feels the reaction force on the brake lever and brake
pedal. This is a normal condition. It informs the rider that
the ABS is operating normally.
○
Service codes detected once by the ABS hydraulic unit
will be memorized in the ABS hydraulic unit. Therefore,
after maintenance work is finished, be sure to erase the
service codes. Do not erase the service codes during
troubleshooting. Wait until all the checks and repair work
are finished to prevent duplication of previous service
codes and unnecessary maintenance work.
○
Before delivering the motorcycle to the customer, be
sure to erase any service codes which might be stored in
the ABS hydraulic unit. Using the self-diagnosis feature,
make sure that the ABS indicator light (LED) lights. A
fully charged battery is a must for conducting reliable
self-diagnosis. Test run the motorcycle at a speed of
more than 20 km/h (12 mph) to see that the ABS indicator
light (LED) does not come on. Finally, test run the mo-
torcycle at a speed of more than 30 km/h (20 mph) and
brake suddenly to see that the motorcycle stops without
loss of steering control and the ABS operates normally
(The reaction force generated is felt in the brake lever
and pedal.). This completes the final inspection.
ABS Troubleshooting Outline
When an abnormality in the system occurs, the ABS in-
dicator light (LED) lights up to alert the rider. In addition,
the nature of the fault is stored in the memory of the ABS
hydraulic unit and when in the self-diagnosis mode, the ser-
vice code [A] is indicated by the number of times the ABS
indicator light (LED) blinks. The service codes stored in
memory are not erased until the mode has been changed
to the fault erase mode after the fault has been corrected.
Therefore, after correcting the problem, always erase the
service codes and then run the self-diagnosis program to
confirm normal signal output. When, due to a malfunction,
the ABS indicator light (LED) remains lit, get a thorough
understanding of the background before starting the repair
work. Ask the rider about the conditions [B] under which
the problem occurred and try to determine the cause [C].
Do not rely solely on the ABS self-diagnosis function, use
common sense; check the brakes for proper braking power,
and brake fluid level, search for leaks, etc.

12-36 BRAKES
Anti-Lock Brake System (Equipped Models)
Even when the ABS is operating normally, the ABS indi-
cator light (LED) may light up under the conditions listed be-
low. Turn the ignition switch OFF to stop the indicator light.
If the motorcycle runs without erasing the service code, the
light may light up again.
○
After continuous riding on a rough road.
○
When the engine is started with the stand raised and the
transmission engaged, and the rear wheel turns.
○
When accelerating so abruptly that the front wheel leaves
the ground.
○
When the ABS has been subjected to strong electrical
interference.
○
When tire pressure is abnormal. Adjust tire pressure.
○
When a tire different in size from the standard size is being
used. Replace with standard size.
○
When the wheel is deformed. Replace the wheel.
Much of the ABS troubleshooting work consists of con-
firming continuity of the wiring. The ABS parts are assem-
bled and adjusted by the manufacturer, so there is no need
to disassemble or repair them. Replace the ABS hydraulic
unit.
The basic troubleshooting procedures are listed below.
•
Carry out pre-diagnosis inspections as a preliminary in-
spection.
•
Determine the fault using the self-diagnosis function.
•
Check wiring and connections from the ABS hydraulic
unit connector to the suspected faulty ABS part, using the
hand tester.
Special Tool - Hand Tester: 57001-1394
•
Visually inspect the wiring for signs of burning or fraying.
If any wiring is poor, replace the damaged wiring.
•
Pull each connector [A] apart and inspect it for corrosion,
dirt and damage.
If the connector is corroded or dirty, clean it carefully. If it
is damaged, replace it.
•
Check the wiring for continuity.
○
Use the wiring diagram to find the ends of the lead which
is suspected of being a problem.
○
Connect the hand tester between the ends of the leads.
Special Tool - Hand Tester: 57001-1394
○
Set the tester to the × 1 Ω range, and read the tester.
If the tester does not read 0 Ω, the lead is defective. Re-
place the main harness [B] if necessary.
•
Narrow down suspicious parts and close in on the faulty
ABS part by repeating the continuity tests.
If no abnormality is found in the wiring or connectors, the
ABS parts are the next likely suspects. Check each part
one by one.
If an abnormality is found, replace the affected ABS part.

Self-diagnosis Outline
When the indicator light has blinked or come on, the ABS hydraulic unit memorizes and stores the
service code (17 codes including “Normal Code”) for the service person to troubleshoot easily. The
service code memory is powered directly by the battery and cannot be canceled by the ignition switch.
The ABS hydraulic unit can memorize up to all service codes (17 codes). Further service codes are
memorized after erasing the preceding all service codes (17 codes). If there is no fault, only the start
code 12 is shown, indicating that “The ABS is normal”.
Self-diagnosis Procedures
○
When a problem occurs with the ABS system, the ABS
indicator light (LED) [A] lights.
NOTE
○
Use a fully charged battery when conducting
self-diagnosis. Otherwise, the light blinks very slowly
or doesn’t blink.
○
The motorcycle is stopped.
○
Keep the self-diagnosis terminal grounded during self
-diagnosis, with an auxiliary lead.

BRAKES 12-41
Anti-Lock Brake System (Equipped Models)
•
Remove the rear seat (see Rear Seat Removal in the
Frame chapter).
•
Turn on the ignition switch.
•
Ground the self-diagnosis terminal [A] (Gray) to the bat-
tery (–) terminal, using a suitable lead.
○
Count the blinks of the light to read the service code.
Keep the auxiliary lead ground until you finish reading the
service code.
Service Code Clearing Procedures
•
Start the service code erase mode with the following pro-
cedure.
○
The erase mode starts when the ABS self-diagnosis ter-
minal is disconnected from the ground terminal after start-
ing the self-diagnosis mode.
○
The service code can be erased by grounding and un-
grounding (each time for at least one second) the ABS
self-diagnosis terminal three times within about 12.5 sec-
onds after starting the erase mode.
○
The ABS indicator light (LED) remains lit during the erase
mode.
○
After erasing, the ABS indicator light (LED) blinks and
lights.
○
Once erasing is finished, enter the self-diagnosis mode
again to confirm that the service codes have been
erased. If the ABS has been reset and all codes have
been erased, only start code 12 will be shown.

How to Read Service Codes
○
Service codes are shown by a series of long and short blinks of the ABS indicator light (LED) as
shown below.
○
Read 10th digit and unit digit as the ABS indicator light (LED) blinks.
○
When there are a number of faults, a maximum of all service codes (17 codes) can be stored and
the display will begin starting from the small number code entered.
○
For the display pattern, first the smallest number code is shown, next up to all service codes (17
codes) starting with the last one stored, then the display is repeated from the smallest number code
once again.
○
If there is no fault, the ABS indicator light (LED) lights as shown in the figure.
How to Erase Service Codes
○
Even if the ignition switch is turned OFF, the battery or the ABS hydraulic unit are disconnected, all
service codes remain in the ABS hydraulic unit.
○
Refer to the Service Code Clearing Procedure for the service code erasure.

Precautions
There are a number of important precautions that are
musts when servicing electrical systems. Learn and ob-
serve all the rules below.
○
Do not reverse the battery cable connections. This will
burn out the diodes on the electrical parts.
○
Always check battery condition before condemning other
parts of an electrical system. A fully charged battery is a
must for conducting accurate electrical system tests.
○
The electrical parts should never be struck sharply, as
with a hammer, or allowed to fall on a hard surface. Such
a shock to the parts can damage them.
○
To prevent damage to electrical parts, do not disconnect
the battery cables or any other electrical connections
when the ignition switch is ON, or while the engine is
running.
○
Because of the large amount of current, never keep the
starter button pushed when the starter motor will not turn
over, or the current may burn out the starter motor wind-
ings.
○
Take care not to short the cables that are directly con-
nected to the battery positive (+) terminal to the chassis
ground.
○
Troubles may involve one or in some cases all items.
Never replace a defective part without determining what
CAUSED the failure. If the failure was caused by some
other item or items, they must be repaired or replaced, or
the new replacement will soon fail again.
○
Make sure all connectors in the circuit are clean and tight,
and examine wires for signs of burning, fraying, etc. Poor
wires and bad connections will affect electrical system op-
eration.
○
Measure coil and winding resistance when the part is cold
(at room temperature).

ELECTRICAL SYSTEM 16-23
Electrical Wiring
Wiring Inspection
•
Visually inspect the wiring for signs of burning, fraying,
etc.
If any wiring is poor, replace the damaged wiring.
•
Pull each connector [A] apart and inspect it for corrosion,
dirt, and damage.
If the connector is corroded or dirty, clean it carefully. If it
is damaged, replace it.
•
Check the wiring for continuity.
○
Use the wiring diagram to find the ends of the lead which
is suspected of being a problem.
○
Connect the hand tester between the ends of the leads.
Special Tool - Hand Tester: 57001-1394
○
Set the tester to the × 1 Ω range, and read the tester.
If the tester does not read 0 Ω, the lead is defective. Re-
place the lead or the wiring harness [B] if necessary.

Battery Activation
Electrolyte Filling
•
Make sure that the model name [A] of the electrolyte con-
tainer matches the model name [B] of the battery. These
names must be the same.
Battery Model Name
ZR1000D/E: YTX9-BS
NOTICE
Each battery comes with its own specific elec-
trolyte container; using the wrong container may
overfill the battery with incorrect electrolyte, which
can shorten battery life and deteriorate battery per-
formance. Be sure to use the electrolyte container
with the same model name as the battery since the
electrolyte volume and specific gravity vary with
the battery type.

ELECTRICAL SYSTEM 16-25
Battery
NOTICE
Do not remove the aluminum sealing sheet [A] from
the filler ports [B] until just prior to use. Be sure to
use the dedicated electrolyte container for correct
electrolyte volume.
DANGER
Sulfuric acid in battery electrolyte can cause severe
burns. To prevent burns, wear protective clothing
and safety glasses when handling electrolyte. If
the electrolyte comes in contact with your skin or
eyes, wash the area with liberal amounts of water
and seek medical attention for more severe burns.
•
Place the battery on a level surface.
•
Check to see that the sealing sheet has no peeling, tears,
or holes in it.
•
Remove the sealing sheet.
NOTE
○
The battery is vacuum sealed. If the sealing sheet has
leaked air into the battery, it may require a longer initial
charge.
•
Remove the electrolyte container from the vinyl bag.
•
Detach the strip of caps [A] from the container and set
aside, these will be used later to seal the battery.
NOTE
○
Do not pierce or otherwise open the sealed cells [B] of
the electrolyte container. Do not attempt to separate
individual cells.
•
Place the electrolyte container upside down with the six
sealed cells into the filler ports of the battery. Hold the
container level, push down to break the seals of all six
cells. You will see air bubbles rising into each cell as the
ports fill.
NOTE
○
Do not tilt the electrolyte container.

16-26 ELECTRICAL SYSTEM
Battery
•
Check the electrolyte flow.
If no air bubbles [A] are coming up from the filler ports, or
if the container cells have not emptied completely, tap the
container [B] a few times.
NOTE
○
Be careful not to have the battery fall down.
•
Keep the container in place. Don’t remove the container
from the battery, the battery requires all the electrolyte
from the container for proper operation.
NOTICE
Removal of the container before it is completely
empty can shorten the service life of the battery.
Do not remove the container until it is completely
empty.
•
After filling, let the battery sit for 20 ∼ 60 minutes with the
electrolyte container kept in place, which is required for
the electrolyte to fully permeate into the plates.
•
Make sure that the container cells have emptied com-
pletely, and remove the container from the battery.
•
Place the strip of caps [A] loosely over the filler ports,
press down firmly with both hands to seat the strip of caps
into the battery (don’t pound or hammer). When properly
installed, the strip of caps will be level with the top of the
battery.
NOTICE
Once the strip of caps is installed onto the battery,
never remove the caps, nor add water or electrolyte
to the battery.
NOTE
○
Charging the battery immediately after filling can
shorten service life.

ELECTRICAL SYSTEM 16-27
Battery
Initial Charge
•
Newly activated sealed batteries require an initial charge.
Standard Charge:
0.9 A × 5
∼ 10 hours
If using a recommended battery charger, follow the
charger’s instructions for newly activated sealed battery.
Kawasaki-recommended chargers:
Battery Mate 150-9
OptiMate PRO 4-S/PRO S/PRO2
Yuasa MB-2040/2060
Christie C10122S
If the above chargers are not available, use equivalent
one.
•
Let battery sit 30 minutes after initial charge, then check
voltage using a voltmeter. (Voltage immediately after
charging becomes temporarily high. For accurate mea-
suring, let the battery sit for given time.)
NOTE
○
Charging rates will vary depending on how long the
battery has been stored, temperature, and the type of
charger used. If voltage is not at least 12.8 V, repeat
charging cycle.
○
To ensure maximum battery life and customer satisfac-
tion, it is recommended the battery be load tested at
three times its amp-hour rating for 15 seconds.
Re-check voltage and if less than 12.8 V repeat the
charging cycle and load test. If still below 12.8 V the
battery is defective.
Precautions
1) No need of topping-up
No topping-up is necessary in this battery until it ends its life under normal use. F
orcibly prying
off the seal cap to add water is very dangerous. Never do that.
2) Refreshing charge.
If an engine will not start, a horn sounds weak, or lamps are dim, it indicates the battery has been
discharged. Give refresh charge for 5 to 10 hours with charge current shown in the specification
(see Refreshing Charge).
When a fast charge is inevitably required, do it following precisely the maximum charge current
and time conditions indicated on the battery.
NOTICE
This battery is designed to sustain no unusual deterioration if refresh-charged according
to the method specified above. H
owever, the battery’s performance may be reduced no-
ticeably if charged under conditions other than given above. Never remove the seal cap
during refresh charge.
If by chance an excessive amount of gas is generated due to overcharging, the relief valve
releases the gas to keep the battery normal.
3) When you do not use the motorcycle for months.
Give a refresh charge before you store the motorcycle and store it with the negative cable re-
moved. Give a refresh charge once a month during storage.
4) Battery life.
If the battery will not start the engine even after several refresh charges, the battery has ex-
ceeded its useful life. Replace it (Provided, however, the vehicle’s starting system has no prob-
lem).

16-28 ELECTRICAL SYSTEM
Battery
DANGER
Batteries produce an explosive gas mixture of hydrogen and oxygen that can cause seri-
ous injury and burns if ignited. Keep the battery away from sparks and open flames during
charging. When using a battery charger, connect the battery to the charger before turning
on the charger. This procedure prevents sparks at the battery terminals which could ignite
any battery gases. The electrolyte contains sulfuric acid. Be careful not to have it touch
your skin or eyes. If touched, wash it off with liberal amount of water and seek medial at-
tention for more severe burns.
Interchange
A sealed battery can fully display its performance only when combined with a proper vehicle electric
system. Therefore, replace a sealed battery only on a motorcycle which was originally equipped with
a sealed battery.
Be careful, if a sealed battery is installed on a motorcycle which had an ordinary battery as original
equipment, the sealed battery’s life will be shortened.
Charging Condition Inspection
○
Battery charging condition can be checked by measuring
battery terminal voltage with a digital voltmeter [A].
•
Remove:
Seats (see Seats section in the Frame chapter)
•
Disconnect the battery terminals.
NOTICE
Be sure to disconnect the negative (–) cable first.
•
Measure the battery terminal voltage.
NOTE
○
Measure with a digital voltmeter which can be read one
decimal place voltage.
If the reading is 12.8 V or more, no refresh charge is re-
quired, however, if the read is below the specified, refresh
charge is required.

Alternator Inspection
There are three types of alternator failures: short, open
(wire burned out), or loss in rotor magnetism. A short or
open in one of the coil wires will result in either a low output,
or no output at all. A loss in rotor magnetism, which may be
caused by dropping or hitting the alternator, by leaving it
near an electromagnetic field, or just by aging, will result in
low output.

16-34 ELECTRICAL SYSTEM

•
To check the alternator output voltage, do the following
procedures.
○
Turn off the ignition switch.
○
Support the fuel tank with a suitable bar [A] (see Fuel Tank
Removal in the Fuel System (DFI) chapter).
○
Disconnect the alternator lead connector [B] (see alterna-
tor Cover Removal).
○
Connect the hand tester as shown in the table 1.
○
Start the engine.
○
Run it at the rpm given in the table 1.
○
Note the voltage readings (total 3 measurements).

If the output voltage shows the value in the table, the al-
ternator operates properly.
If the output voltage shows a much higher than the value
in the table, the regulator/rectifier is damaged. A much
lower reading than that given in the table indicates that
the alternator is defective.
•
Check the stator coil resistance as follows.
○
Stop the engine.
○
Connect the hand tester as shown in the table 2.
○
Note the readings (total 3 measurement).

If there is more resistance than shown in the table, or no
hand tester reading (infinity) for any two leads, the stator
has an open lead and must be replaced. Much less than
this resistance means the stator is shorted, and must be
replaced.
•
Using the highest resistance range of the hand tester,
measure the resistance between each of the black leads
and chassis ground.
Any hand tester reading less than infinity (∞) indicates a
short, necessitating stator replacement.
If the stator coils have normal resistance, but the voltage
check showed the alternator to be defective; then the rotor
magnets have probably weakened, and the rotor must be
replaced.

Rectifier Circuit Inspection
W1-BK1, W1-BK2, W1-BK3
Tester connection
BK/Y-BK1, BK/Y-BK2, BK/Y-BK3
The resistance should be low in one direction and more
than ten times as much in the other direction. If any two
terminals are low or high in both directions, the rectifier is
defective and the regulator/rectifier must be replaced.
NOTE
○
The actual meter reading varies with the meter used
and the individual rectifier, but, generally speaking the
lower reading should be from zero to one half the scale.
Regulator Circuit Check
To test the regulator out of circuit, use three 12 V batteries
and a test light (12 V 3 ∼ 6 W bulb in a socket with leads).
NOTICE
The test light works as an indicator and also a cur-
rent limiter to protect the regulator/rectifier from ex-
cessive current. Do not use an ammeter instead of
a test light.
•
Check to be sure the rectifier circuit is normal before con-
tinuing.

16-36 ELECTRICAL SYSTEM
Charging System
•
Do the 1st step regulator circuit test.
○
Connect the test light and the 12 V battery to the regula-
tor/rectifier as shown in the figure.
○
Check the BK1, BK2 and BK3 terminal respectively.
If the test light turns on, the regulator/rectifier is defective.
Replace it.
If the test light does not turn on, continue the test.
•
Do the 2nd step regulator circuit test.
○
Connect the test light and the 12 V battery in the same
manner as specified in the “Regulator Circuit Test-1st
Step”.
○
Apply 12 V to the W2 terminal.
○
Check the BK1, BK2 and BK3 terminal respectively.
If the test light turns on, the regulator/rectifier is defective.
Replace it.
If the test light does not turn on, continue the test.
•
Do the 3rd step regulator circuit test.
○
Connect the test light and the 12 V battery in the same
manner as specified in the “Regulator Circuit Test-1st
Step”.
○
Momentarily apply 24 V to the W2 terminal by adding a
12 V battery.
○
Check the BK1, BK2 and BK3 terminals respectively.
NOTICE
Do not apply more than 24 V. If more than 24 V is ap-
plied, the regulator/rectifier may be damaged. Do
not apply 24 V more than a few seconds. If 24 V
is applied for more than a few seconds, the regula-
tor/rectifier may be damaged.
If the test light did not light when the 24 V was applied
momentarily to the voltage monitoring terminal, the regu-
lator/rectifier is defective. Replace it.
If the regulator/rectifier passes all of the tests described,
it may still be defective. If the charging system still does
not work properly after checking all of the components
and the battery, test the regulator/rectifier by replacing it
with a known good unit.

•
Start the engine, and note the voltage readings at var-
ious engine speeds with the headlight turned on and
then turned off (To turn off the headlight, disconnect
the headlight connector on the headlight unit.). The
readings should show nearly battery voltage when the
engine speed is low, and, as the engine speed rises, the
readings should also rise. But they must be kept under
the specified voltage.

If the charging voltage is kept between the values given in
the table, the charging system is considered to be working
normally.
If the charging voltage is much higher than the values
specified in the table, the regulator/rectifier is defective
or the regulator/rectifier leads are loose or open.
If the charging voltage does not rise as the engine speed
increases, then the regulator/rectifier is defective or the
alternator output is insufficient for the loads. Check the

Immobilizer System (Equipped Models), ZR1000DA/EA
This motorcycle is equipped with an immobilizer system to protect the motorcycle from theft. This
system provides a theft proof device by means of matching a code between the inbuilt key transponder
and ECU (Electronic Control Unit). If the code does not match, ignition system, injectors, subthrottle
valve actuator and exhaust butterfly valve actuator will not operate and the engine will not start.
Abstract
•
Do not keep more than one immobilizer key of any system on a key ring. Jamming of the key code
signal may occur and the operation of the system may be affected.
•
The warning indicator light (LED) will flash for a period of 24 hours once the ignition switch has been
switched off and the key removed. This flashing can be set to on or off as desired by holding the
left and right buttons down for two seconds within twenty seconds of switching the ignition off.
•
If all coded keys (master key and user keys) are lost the ECU and ignition switch will have to be
replaced.
•
The immobilizer system can not function until the master key code is registered in the ECU.
•
A total of six keys can be registered in the ECU at any one time (one master key and five user keys).
•
If the master key is lost it is not possible to register new user keys.
Operational Cautions
1. Do not put two keys of any immobilizer system on the same key ring.
2. Do not submerge any key in water.
3. Do not expose any key to excessively high temperature.
4. Do not place any key close to magnet.
5. Do not place a heavy item on any key.
6. Do not grind any key or alter its shape.
7. Do not disassemble the plastic part of any key.
8. Do not drop the key and/or apply any shocks to the key.
9. When a user key is lost, the user should go to his dealer to invalidate the lost key registration in
the ECU.
10.When the master key is lost, the user should go to his dealer and have a new ECU installed and
register a new master key and user keys.
NOTE
○
No.9 and 10 are strongly recommended to the customer to ensure security of the motorcycle.

16-98 ELECTRICAL SYSTEM
Immobilizer System (Equipped Models), ZR1000DB ∼/EB ∼
This motorcycle is equipped with an immobilizer system to protect the motorcycle from theft. This
system provides a theft proof device by means of matching a code between the inbuilt key transponder
and ECU (Electronic Control Unit). If the code does not match, ignition system, injectors, subthrottle
valve actuator and exhaust butterfly valve actuator will not operate and the engine will not start.
Abstract
•
Do not keep more than one immobilizer key of any system on a key ring. Jamming of the key code
signal may occur and the operation of the system may be affected.
•
The warning indicator light (LED) will flash for a period of 24 hours once the ignition switch has been
switched off and the key removed. This flashing can be set to on or off as desired by holding the
left and right buttons down for two seconds within twenty seconds of switching the ignition off.
•
If all coded keys are lost the ECU and ignition switch will have to be replaced.
•
The immobilizer system can not function until the ignition key code is registered in the ECU.
•
A total of five keys can be registered in the ECU at any one time.
Operational Cautions
1. Do not put two keys of any immobilizer system on the same key ring.
2. Do not submerge any key in water.
3. Do not expose any key to excessively high temperature.
4. Do not place any key close to magnet.
5. Do not place a heavy item on any key.
6. Do not grind any key or alter its shape.
7. Do not disassemble the plastic part of any key.
8. Do not drop the key and/or apply any shocks to the key.
9. When a ignition key is lost, the user should go to his dealer to invalidate the lost key registration
in the ECU.
10.When the all ignition key is lost, the user should go to his dealer and have a new ECU installed
and register the ignition keys.
NOTE
○
No.9 and 10 are strongly recommended to the customer to ensure security of the motorcycle.
