What to do when the engine is
“flooded”
In the event of a fall, more fuel than
necessary may get into the engine. In
order to “pump the engine free”, fully
rev up the engine, actuate the kick-
starter 5 to 10 times or actuate the
electric starter twice for 5 seconds
each. Then, start the engine as
described above.
If the engine fails to start, unscrew the
spark plug and dry it.
NOTE: PR3 carburettor is equipped
with an acceleration pump (Power Jet).
Each time you open the throttle, extra
fuel is pumped to engine inlet.
Therefore, when starting, you should
take care to open the throttle
progressively (or full) in one time.
! WARNING !
- If you want to start the engine with
kick start pedal, make sure you
always put on rigid motorcycle boots
in order to avoid injuries. You might
slip off the kick-starter or the engine
may kick back and hit your foot
upward very strongly.
- Always kick kick-starter briskly all
the way without opening the throttle;
if you don’t do it with enough
momentum and with the throttle
open, kick back hazard will increase.
- Do not start the engine or allow it
to idle in a closed area. Exhaust
gases are poisonous and can cause
loss of consciousness and even
death. Always provide adequate
ventilation while the engine is
running.
- Never leave engine running for a
more than 5 minutes while the
motorcycle is parked: engine will
overheat and severe damage may
occur.
STARTING OFF
Pull the clutch lever and put the engine
into first gear. Slowly release the clutch
lever and open the throttle at the same
time.
USING THE GEARBOX
The first gear is referred as the drive or
uphill gear. Depending on the
conditions (traffic, hill size, etc.), you
can shift to a higher gear. Close
throttle, at the same time you pull clutch
lever and shift to the next higher gear.
Let clutch go again and give gas. If you
turned on the choke lever, make sure
you turn it off again as soon as engine
is warm.
When you reach full speed by opening
the throttle all the way, turn throttle
back to ¾; the speed hardly decreases
and the engine will use less fuel.
Only give as much gas as the engine
can handle. Through quick and high
revving of throttle, the fuel consumption
increases.
By shifting down, use the brakes if
necessary and close throttle at the
same time. Pull clutch lever and shift
down to the next gear. Let clutch lever
go slowly and open throttle or shift
down again.
! CAUTION !
- High RPM speed when engine is
cold have an adverse effect on the
life of your engine. We recommend
you to run the engine in a
moderate RPM range for 5/10
Kilometers/miles giving it the
chance to warm up.
- Never have the throttle wide open
when shifting down a gear. The
engine will over-rev, damaging the
valves.
- If any abnormal vibrations occur
while driving, check that the engine
fastening bolts are tight. If it
remains contact an authorized AJP
dealer.
- If you notice any unusual
operation-related noise while riding,
stop immediately, shut the engine
off and contact an authorized AJP
dealer.
