Throttle Cable Inspection
Verify the throttle trigger operates smoothly and the throttle cable is undamaged. If there is visible 
damage, or if the throttle trigger does not operate smoothly, have your authorized Honda servicing 
dealer replace the throttle cable.

Check the free play at the end of the throttle cable.

Free play (all models):  1/16 ~ 1/8 in (1.0 ~ 3.0 mm)

If adjustment is needed, use the following cable adjustment procedure.

Throttle Cable Adjustment
1. Loosen the lock nut with a 10 mm wrench, and turn the adjusting nut in or out as required.
2. Tighten the lock nut and recheck cable free play.
