Additional Maintenance Procedures

Refer to Safety Precautions on page 27.

Steering Head Bearing Inspection

1. With your CRF on a box or optional workstand
(front wheel elevated), turn the handlebar to
the right and left to check for roughness in the
steering head bearings.
2. Stand in front of your CRF, grab the fork (at
the axle), look at the steering head, and push
the fork in and out (toward the engine) to check
for play in the steering head bearings.
If any roughness or play is felt, but you do not
see any movement in the steering head, the
fork bushings may be worn. Refer to an official
Honda Shop Manual for replacement or
adjustment procedures, or see your Honda
dealer.

Handlebar Inspection

1. Check the handlebar (1) for bends or cracks.
2. Check that the handlebar has not moved from
its proper position (the end of the right
handlebar holders (2) is aligned with the paint
mark (3)).
3. Check the torque of the handlebar upper holder
bolts (4):
22 N·m (2.2 kgf·m, 16 lbf·ft)
Tighten the front bolts first.

Control Cables

Periodically, disconnect the throttle and clutch
cables at their upper ends. Thoroughly lubricate
the cable pivot points with a commercially
available cable lubricant. If the clutch lever and
throttle operation is not smooth, replace the cable.
Be sure the throttle returns freely from fully open
to fully closed automatically, in all steering
positions.
