The vehicle speed limiter keeps the throttle from fully
opening, even when the throttle lever is pushed to the
maximum. The adjusting screw may be gradually
turned out as the beginner becomes more familiar with
operating the ATV. Parents should decide when to
adjust the ATV for more power as their youngster’s
riding skills improve. Once the ATV rider can operate
with skill at the top speed permitted by adjusting the
vehicle speed limiter alone, the engine speed limiter
plate can be removed. Since removal of this limiter
will result in a significant increase in power, turn the
vehicle speed limiter adjusting screw completely back
in again; adjust it out in stages as done previously.
