Throttle Lever; Speed Limiter - Yamaha Grizzly 300 Owner's Manual

Throttle lever

Once the engine is running, pushing the throttle
lever will increase the engine speed.
Regulate the speed of the ATV by varying the throttle
position. Because the throttle is spring-loaded, the
ATV will decelerate, and the engine will return to an
idle any time the throttle lever is released.
