General Competition Maintenance
Servicing Your Honda 29
Handgrips
Always use Honda Bond A, Pro Honda Handgrip Cement
(U.S.A. only) when replacing handgrips.
Refer to an official Honda Service Manual (page 186) for
installation instructions.
Throttle Grip/Handlebar Grip
Right throttle grip: Align the index mark on the throttle grip
with the index mark of the throttle pipe.
Left handlebar grip: Align the index mark on the left
handlebar grip with the paint mark on the handlebar.
Gaskets
Always use new gaskets when reassembling components.
Fuel Line
Refer to Fuel Line Inspection on pages 42 and 52.
Check the fuel line for deterioration, damage, or leakage.
Replace the fuel line every year.
For added security, you may choose to bind the handgrips to
the handlebar and throttle pipe with safety wires to prevent the
possibility of them loosening. Position the twisted wire ends
away from your palms and be sure to bend the wire ends well
into the handgrip rubber so they will not snag your glove.
Engine Mounting Bolts and Nuts
Make sure the engine mounting bolts and nuts are tightened
to the proper torque specification.
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.
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 93, 94).
Electrical Connectors
Clean electrical connectors and wrap them with electrical
tape to reduce the possibility of unwanted disconnections,
water shorts or corrosion.
Fuse
Check the fuse before looking elsewhere for the cause of an
electrical problem.
Battery
The start button uses current from the battery.
Limited operation also allows the battery to discharge. If
you do not ride frequently, we recommend that you charge
the battery frequently (see Battery Charging on page 135).
If you do not expect to ride your CRF for at least 2 weeks,
we recommend you remove the battery – or at least
disconnect the battery cables (negative cable first).
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 186). Use only Pro Honda HP Fork Oil, A15-00 or an
equivalent which contains special additives to assure
maximum performance of your CRF’s front suspension.
