3. Inspect both ends of cable and replace if frayed, kinked
or damaged.
Throttle Cable Adjustment

lock nut.
2. T urn the adjuster in (clockwise) to increase the amount
of throttle lever freeplay. T urn the adjuster out
(counterclockwise) to decrease the amount of freeplay.

4. Start engine and turn handlebars to left and right
through entire turning range. If engine RPM increases
re-check cable condition, routing, and lever free play,
and correct or adjust as necessary.

overheating.
