Speed limiter 

Your ATV was delivered with an adjustable speed

limiter. The speed limiter keeps the throttle from

fully opening, even when the throttle lever is

pushed to the maximum.

1. Loosen the locknut.

2. To increase the maximum engine power avail-

able and the maximum speed of the ATV, turn

the adjusting screw in direction (a). To de-

crease the maximum engine power available

and the maximum speed of the ATV, turn the

adjusting screw in direction (b).

3. Tighten the locknut.
