Servicing Your Honda 67
Clutch System
Cable End Adjustment
Minor adjustments are generally made with the
clutch cable end adjuster.
Turning the cable end adjuster (1) in direction (+)
will increase freeplay and turning it in direction (–)
will decrease freeplay.
If the adjuster is threaded out near its limit or the
correct freeplay cannot be reached, turn the
adjuster all the way in and back out one turn and
make the adjustment with the integral cable
adjuster.
Integral Cable Adjustment
The integral cable adjuster is used if the cable end
adjuster is threaded out near its limit — or the
correct freeplay cannot be obtained.
1. Turn the cable end adjuster in direction (+)
until it seats lightly and then turn it out five
turns.
2. Loosen the lock nut (1).
3. Turn the integral cable adjuster (2) to obtain
the specified freeplay.
4. Tighten the lock nut. Check the freeplay.
5. Start the engine, pull the clutch lever in, and
shift into gear. Make sure the engine does not
stall and the motorcycle does not creep.
Gradually release the clutch lever and open the
throttle. Your CRF should move smoothly and
accelerate gradually.
If you can’t get proper adjustment, or the clutch
does not work properly, the cable may be kinked or
worn, or the clutch discs may be worn.
Inspect the clutch discs and plates (page 69).
• Check that the clutch lever assembly is
positioned properly (the end of the holder (1) is
aligned with the paint mark (2) on the
handlebar) and the securing bolts are tight.
• Check the clutch cable for kinks or signs of
wear. If necessary, have it replaced.
• Lubricate the clutch cable with a commercially
available cable lubricant to prevent premature
wear and corrosion.
1. Check for smooth clutch lever operation. If
necessary, lubricate the clutch lever pivot bolt
sliding surface with grease and/or clutch cable
with commercially available cable lubricant.
2. Check the clutch cable for deterioration, kinks,
or damage.
