Swingarm Pivot Lubrication
Clean, inspect and lubricate all 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
footpegs 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 91).
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: Replace the hydraulic fluid in the
brake system every two 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. Steering Head Bearings
Periodically clean, inspect and regrease the steering head
bearings — especially if wet, muddy or extremely dusty
courses are encountered often. Use Urea based multi-purpose
grease with extreme pressure (example: Kyodo Yushi
EXCELITE EP2, Shell stamina EP2 or equivalent).
Water Leakage Check Hole
After every race, check the leakage check hole, located just
below the water pump cover on the right crankcase cover.
Clean away any clogged dirt or sand, if necessary. Look for
coolant or oil leakage. Leaking coolant indicates a worn or
damaged mechanical seal. Leaking oil indicates a bad
transmission oil seal. If replacement is necessary, both seals
should be replaced.
Fork Oil/Performance
Disassemble, clean and inspect the front fork and replace oil
regularly. Contamination due to the tiny metal particles
produced from the normal action of the fork, as well as
normal oil breakdown, will deteriorate the performance of
the suspension. Refer to the Honda Shop Manual. Use only
Honda ULTRA CUSHION OIL SPECIAL 5W or equivalent
which contains special additives to assure maximum
performance of your CRF’s front suspension.
Frame
Because your CRF is a high-performance machine, the frame
should not be overlooked as part of your overall competition
maintenance program. Periodically inspect the frame
closely for possible cracking or other damage. It makes
good racing sense.
Spokes
Check spoke tension frequently between the first few rides.
As the spokes, spoke nuts and rim contact points seat-in, the
spokes may need to be retightened. Once past this initial
seating-in period, the spokes should hold their tension. Still,
be sure your race maintenance program includes checking
spoke tension and overall wheel condition on a regular basis
(page 92).
Nuts, Bolts, Etc.
Application of a thread locking agent to essential fasteners
offers added assurance and security. Remove the nuts, clean
the threads of both the nuts and bolts, apply Honda Thread
Lock or an equivalent and tighten to the specified torque.
Suspension Linkage Lubrication
Disassemble, clean, inspect and lubricate all pivot bearings
with grease after each 7.5 hours of running time in order to
maintain proper suspension performance and minimize
component wear.
