THE ADJUSTMENT OF THROTTLE LEVER

To adjust the throttle lever free distance:
1.  Loosen the throttle lever adjustment nut
2.  Turn the large adjustment nut  in or out to obtain the correct play.
3.  Tighten the throttle lever adjustment nut.
4.  Recheck the throttle lever free distance.

Readjust it if it is not within the correct limits.

WARNING

Operating the vehicle with an inadequate throttle lever free distance could

be hazardous.

Inadequate throttle lever free distance could cause engine speed to rise

suddenly when you turn the handlebars. This can lead the rider to lose

control.

Adjust the throttle lever free distance so that engine idle speed does not

rise due to handlebar movement.

3.0~5.0mm

(0.12~0.20 inches)

Measure the throttle lever play.
