Before starting the engine, check the throttle to be
sure it is operating smoothly. Make sure it returns
to the idle position as soon as the lever is released.
WARNING
EWB00250
Malfunction of the throttle could make it diffi-
cult to speed up or slow down when you need
to. This could cause an accident. Check the op-
eration of the throttle lever before you start the
engine. If the throttle does not work smoothly,
check for the cause. Correct the problem be-
fore riding the ATV or consult a Yamaha dealer.

Speed limiter and air intake restrictor
plate
Your ATV was delivered with an adjustable speed
limiter and an air intake restrictor plate. Yamaha
recommends that all beginning riders start off with
the speed limiter adjusting screw fully turned in and
the air intake restrictor plate installed to limit the
amount of speed available while they learn.
The speed limiter keeps the throttle from fully
opening, even when the throttle lever is pushed to
the maximum. The adjusting screw may be gradu-
ally turned out as the beginner becomes more fa-
miliar 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 speed limiter alone, the
air intake restrictor plate can be removed. Since re-
moval of this plate will result in a significant in-
crease in power, turn the adjusting screw
completely back in again; adjust it out in stages as
done previously.
1. Loosen the locknut.
2. To increase the maximum engine power avail-
able and the maximum speed of the ATV, turn
1. Throttle lever
