4. SERVICE AND MAINTENANCE
•
Suspension Linkage Lubrication: Disassemble,
clean, inspect and lubricate all pivot bearings after
each 7.5 hours of running time in order to maintain
proper suspension performance and minimize
component wear. Use Honda Moly 60 Paste (U.S.A.
only) or molybdenum disulfide paste (containing
more than 40% molybdenum disulfide additive).
•
Swingarm Pivot Lubrication: Clean, inspect and
lubricate when servicing suspension linkage piv-
ots. Be sure all of the suspension pivot seals are in
good condition. Use Honda Moly 60 Paste (U.S.A.
only) or molybdenum disulfide paste (containing
more than 40% molybdenum disulfide additive).
•
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 triangu-
lar-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: Replace the hydraulic
fluid in the brake system every two years.
•
Water Pump Inspection Hole: After every race, check
the inspection 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 water seal. Leaking oil indicates
a bad transmission oil seal. If replacement is neces-
sary, both seals should be replaced.
•
Brake Caliper Inspection: Be sure both front and
rear calipers are able to move freely on the caliper
bracket pins. Check pad thickness periodically and
replace when minimum thickness is reached.
•
Steering Head Bearings: Periodically clean, inspect
and regrease the steering head bearings—espe-
cially if wet, muddy or extremely dusty courses are
encountered often.
•
Fork Oil/Performance: Disassemble, clean and in-
spect the fork and replace the oil regularly. Con-
tamination 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.
Use only Pro Honda HP Fork Oil 5W or equivalent
which contains special additives to assure maxi-
mum performance of your CR's front suspension.
•
Frame: Because your CR is a high-performance
machine, the frame should not be overlooked as
part of your overall competition maintenance pro-
gram. 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, nipples 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 36)
•
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.
