ADJUSTING THE SPEED LIMITER
The speed limiter keeps the throttle from becom-
ing fully-opened even when the throttle lever is
applied to the maximum position. Screwing in
the adjusting screw stops the engine speed from
increasing.
1. Measure:
• Speed limiter length "a"
Out of specification → Adjust.
Speed limiter length
Less than 12 mm (0.47 in)
2. Adjust:
• Speed limiter length "a"

WARNING
• Particularly for a beginner rider, the speed
limiter should be screwed in completely.
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 the speci-
fied length. Also, always adjust the throttle
cable free play to within specification.
