GREASE
GREASE
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 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.
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.
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.
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).
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.
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.
