a cable tie; then install the handlebar pad.

„ NOTE: At this point, spray the binding screw
drum (located on the carburetor throttle arm) with
WD-40 or an equivalent lubricant.

ADJUSTING

1. The correct throttle cable adjustment is when

(with the engine OFF) the carburetor throttle is

completely open (against its limit) while the

throttle control lever lightly contacts the hand

grip. The throttle arm on the carburetor should

also contact the throttle stop screw when the

throttle control is released. Adjust by using the

following procedure.

2. Loosen the throttle cable wire binding screw.
