General Competition Maintenance

Servicing Your Honda
Gaskets
Always use new gaskets when reassembling components.
Cylinder head/Cylinder
Put a little grease on the dowel pins of the cylinder head and
cylinder to prevent corrosion from dissimilar metals. The
tolerances are quite tight, so it’s important to keep these
dowels absolutely clean (pages 77, 79).
Fuel Line
Refer to
Fuel Line Inspection
Check the fuel line for deterioration, damage, or leakage.
Replace the fuel line every year.
Engine Mounting Bolts and Nuts
Make sure the engine mounting bolts and nuts are tightened
to the proper torque specification. For added peace of mind,
remove the nuts, clean the threads, and apply Pro Honda
Hondalock or an equivalent prior to torquing the nuts.
Electrical Connectors
Clean electrical connectors and wrap them with electrical tape
to reduce the possibility of unwanted disconnections, water
shorts or corrosion. Additional corrosion protection is offered
by using Pro Honda Dielectric Grease on all electrical
connections.
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 115).
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 an official Honda Service Manual
(page 174). Use only HP Fork Oil, SS-19 or an 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).
