General Competition Maintenance
Servicing Your Honda 29
Brake Fluid Replacement
Refer to Brake Pad Wear on page 101.
Brake Caliper Inspection: Be sure both the front and rear
calipers are able to move freely on the caliper pin and caliper
bracket pins. Check pad thickness periodically and replace the
pads when minimum thickness is reached. If the brakes fade
when they are hot, inspect the pads for glazing or damage, and
replace if necessary.
Brake Fluid Replacement: Refer to an official Honda Service
Manual (page 172) for brake fluid replacement instructions.
Replace the brake fluid in the brake system every 2 years.
Replace the fluid more frequently if you subject your brakes to
severe use. Heavy braking heats the brake fluid and it may
deteriorate sooner than expected. Any type of riding, that
requires frequent use of the brakes, such as in tight woods, can
shorten the service life of brake fluid.
Bleed Hole
After every race, check the bleed hole below the water pump
cover for leakage. Clean away any clogged dirt or sand, if
necessary. Check the bleed hole of the water pump for signs
of seal leakage. If water leaks through the bleed hole, replace
the mechanical seal. If oil leaks through the bleed hole, replace
the oil seal. Make sure that there is no continuous coolant
leakage from the bleed hole while operating the engine. A
small amount of coolant weeping from the bleed hole is
normal. See an official Honda Service Manual or consult your
dealer for replacing the mechanical seal or oil seal. Both seals
should be replaced at the same time.
Suspension Linkage Lubrication
Disassemble, clean, inspect and lubricate all suspension linkage
pivot bearings with molybdenum disulfide grease (containing
more than 3% molybdenum disulfide additive) after each 7.5
hours of running time in order to maintain proper suspension
performance and minimize component wear.
Footpegs
Worn footpeg teeth can be repaired by filing the grooves
between the teeth with a triangular shaped file.
Be aware that filing them too sharp will reduce boot sole
lifespan. Sharpen only the points of the teeth. Filing the
grooves deeper will weaken the footpegs. Be sure the pegs
are free to pivot freely and that the pivot pin retaining cotter
pins are in good condition.
Swingarm
Do not attempt to weld or otherwise repair a damaged
swingarm. Welding will weaken the swingarm.
Swingarm Pivot Lubrication
Clean, inspect and lubricate the swingarm and suspension
linkage pivots with molybdenum disulfide grease (containing
more than 3% molybdenum disulfide additive) after each 7.5
hours of running time in order to maintain proper suspension
performance and minimize component wear. Be sure all of the
dust seals are in good condition.
Handgrips
Always use Pro Honda Handgrip Cement or an equivalent
when replacing handgrips.
Refer to an official Honda Service Manual (page 172) for
installation instructions.
Throttle Grip
Right throttle grip: Align the index mark on the throttle grip
with the index mark of the throttle pipe.
Left handlebar grip: Align the index mark on the left
handlebar grip with the paint mark on the handlebar.
For added security, you may choose to bind the handgrips to
the handlebar and throttle pipe with safety wires to prevent the
possibility of them loosening. Position the twisted wire ends
away from your palms and be sure to bend the wire ends well
into the handgrip rubber so they will not snag your glove.
Throttle Control
Remove the throttle control every few rides, clean the inside
of the throttle pipe and handlebar thoroughly. Inspect the cable
carefully for kinks or other damage that may restrict throttle
control in anyway. Move the handlebar from lock to lock to be
sure there is no cable interference. Make certain the throttle
operation is perfect after servicing and inspecting.
