32 Servicing Your Honda
General Competition Maintenance
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 ling the grooves
between the teeth with a triangular shaped le.
Be aware that ling 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 pins 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 the Honda Service
Manual (Page 174) for brake uid replacement instructions.
Replace the hydraulic uid in the brake system every 2
years. Replace the uid more frequently if you subject your
brakes to severe use. Heavy braking heats the brake uid 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 uid.
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 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 Service Manual
(page 174). Use only Pro Honda HP Fork Oil 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 rst 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 Pro Honda
Hondalock or an equivalent and tighten to the specied
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.
