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 for signs of seal leakage. A small amount
of “coolant weeping” from the bleed hole is normal. If water
leaks through the bleed hole, the mechanical seal is
damaged. If oil leaks through the bleed hole, the oil seal is
damaged. 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 grease after each 7.5 hours of
running time in order to maintain proper suspension
performance and minimize component wear.
Swingarm Pivot Lubrication
Clean, inspect and lubricate swingarm and suspension
linkage pivots with grease. Be sure all of the dust seals are
in good condition.
Swingarm
Do not attempt to weld or otherwise repair a damaged
swingarm. Welding will weaken the swingarm.
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.
Brake Fluid Replacement
Refer to Brake Pad Wear in your Owner’s Manual, page 93.
Brake Caliper Inspection: Be sure both the front and rear
calipers are able to move freely on the 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 the Honda Service
Manual (page 160) for brake fluid replacement instructions.
Replace the hydraulic 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.
Handgrips
Always use Pro Honda Handgrip Cement when replacing
handgrips.
Throttle Grip
Align the index mark on the throttle grip with the edge of the
throttle cable guide. Left handlebar grip: Align the “∆” mark
on the left handlebar grip with the paint mark on the
handlebar.
Refer to the Service Manual for installation
instructions.
For added security, you may choose to bind the hand grips 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 the handlebar thoroughly. Inspect the
cable carefully for kinks or other damage that may restrict
throttle control in any way. 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.
