Refer to
Important Safety Precautions
Inspection
Check freeplay (1).
Freeplay:
1/16 – 1/4 in (2 – 6 mm)
If necessary, adjust to the specified range.
Upper Adjustment
Minor adjustments are generally made with the
upper adjuster.
1. Loosen the lock nut (1).
2. Turn the adjuster (2).
Turning the adjuster in direction (–) will
decrease freeplay and turning it in direction (+)
will increase freeplay.
3. Tighten the lock nut securely.
4. 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 securely.
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 throttle body. It is also used
if you cannot get the proper adjustment with the
upper adjuster.
1. Loosen the lock nut (1).
2. Turn the adjuster (2) in direction (–) to
decrease freeplay, and in direction (+) to
increase freeplay.
3. Tighten the lock nut to the specified torque:
3.0 lbf·ft (4.0 N·m, 0.4 kgf·m)
4. Operate the throttle grip to ensure that it
functions smoothly and returns completely.
If you can’t get the freeplay within the specified
range, contact your dealer.
