General Competition Maintenance
Handgrips
Always use Hand Grip Cement when replacing handgrips.
Throttle grip
Align the index mark on the throttle grip with the edge of the
throttle cable guide. Left handlebar grip: Align the " " mark
on the left handlebar grip with the paint mark on the
handlebar.
Refer to the Honda Shop Manual for installation instructions.
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.
Throttle Control
Remove the throttle control every few rides, clean the inside
of the throttle pipe and handlebar thoroughly. Inspect the
cable carefully for kinks or other damage that may restrict
throttle control in any way. Move the handlebar from lock to
lock to be sure there is no cable interference. Make certain
the throttle operation is perfect after servicing and
inspecting.

Servicing Your Honda
Fuel Filter
Periodically drain the fuel from the fuel tank, remove and clean
the fuel valve and fuel filter. Replace the fuel valve O-ring if
there are any signs of damage or deterioration (page 41).
Cylinder Removal
Put a little grease on the cylinder mounting dowels to
prevent corrosion from dissimilar metals. The tolerances are
extremely tight, so it's important to keep these dowels
absolutely clean (page 76).
Engine Mounting Bolts and Nuts
Make sure the engine mounting bolts and nuts are tightened
to the proper torque specification (page 155). For added
peace of mind, remove the nuts, clean the threads, and apply
Honda Thread Lock or an equivalent before torquing the
nuts.
Fuel Contamination
Refer to Fuel System, in your Owner's Manual (page 41).
Check the fuel lines for deterioration, damage, or leakage.
Replace the fuel lines, if necessary.
Periodically drain the fuel from the fuel tank, remove and
clean the fuel valve and fuel filter. Replace the fuel valve
O-ring if there are any signs of damage or deterioration
(page 41).
Loosen the carburetor drain screw and examine the fuel that
flows out of the float bowl. If you notice anything in the
fuel, such as water or dirt, remove the float bowl and inspect
its contents (page 131).
For maximum efficiency, drain and replace fuel that has
been in the fuel tank for more than a month.
Gaskets
Always use new gaskets when reassembling components.
Battery
Electrical accessories use current from the battery – even
when the engine is off.
Limited operation also allows the battery to discharge. If you
have electrical accessories on your CRF – or do not ride
frequently, we recommend that you charge the battery
frequently (see Battery Charging, page 100).
If you do not expect to ride your CRF for at least two weeks,
we recommend you remove the battery – or at least
disconnect the battery cables (negative cable first).
Electrical Connectors
Clean electrical connectors and wrap them with electrical
tape to reduce the possibility of unwanted disconnections,
water shorts or corrosion. For additional corrosion
protection, apply Honda Dielectric Grease to electrical
connections.
