ADJUSTING THE SPEED LIMITER
The speed limiter keeps the carburetor throttle
from becoming fully-opened even when the
throttle lever is applied to the maximum posi-
tion. Screwing in the adjuster stops the engine
speed from increasing.

b. Turn the adjuster in or out until the speci-
fied speed limiter length is obtained.

WARNING

Particularly for a beginner rider, the
speed limiter should be screwed in com-
pletely. Screw it out little by little as their
riding technique improves. Never remove
the speed limiter for a beginning rider.
For proper throttle lever operation do not
turn out the adjuster more than 11.0 mm
(0.43 in). Also, always adjust the throttle
lever free play to 1.0 ~ 3.0 mm (0.04 ~
0.12 in).
