1. Pull the rubber dust cover (2) back.
2. Loosen the upper lock nut (3) on the throttle
cable mechanism.
3. Turn the upper adjuster (4).
Turning the adjuster in direction (–) will
decrease freeplay and turning it in direction
(+) will increase freeplay.
4. Tighten the lock nut. Return the dust cover to
its normal position.
5. After adjustment, check for smooth rotation of
the throttle grip from fully closed to fully
open in all steering positions.
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. Tighten the lock nut, install the dust
cover and make the adjustment with the lower
adjuster.
Lower Adjustment
The lower adjuster is used for major freeplay
adjustment, such as after replacing the throttle
cables or removing the carburetor. It is also used
if you cannot get the proper adjustment with the
upper adjuster.
