Swingarm Pivot Lubrication
Clean, inspect and lubricate the 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.
Fuse
Check the fuse before looking elsewhere for the cause of an
electrical problem.
Brake Fluid Replacement
Refer to Brake Pad Wear in your Owner’s Manual, page 89.
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 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.
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 designed for high
temperature, high pressure performance (example:
EXCELITE EP2 manufactured by KYODO YUSHI, Japan
or Shell Stamina EP2 or equivalent).
Bleed Hole
After every race, check the bleed hole, located just below the
water pump cover on the right crankcase cover. Clean away
any clogged dirt or sand, if necessary. Check for signs of
seal leakage. A small amount of “weeping” from the bleed
hole is normal.
Fork Oil/Performance
Disassemble, clean and inspect the fork and replace the 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 Service Manual (page
168). Use only Pro Honda HP Fork Oil 5W (U.S.A. only) 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 90).
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 Pro Honda
Hondalock or an equivalent and tighten to the specified torque.
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.
