Speed limiter
For riders inexperienced with this model, this
model is equipped with a speed limiter in the
throttle lever housing. The speed limiter limits
the power and top speed of the ATV. Turning
the screw in decreases top speed, and turning it
out increases top speed. This model also has an
air intake restrictor plate to limit the amount of
engine power available.
Yamaha recommends that all beginners start off
with the speed limiter turned in and the air intake
restrictor plate installed to limit the amount of
speed available while they learn. The limiter may
be gradually adjusted to increase maximum speed
as the beginner becomes more familiar with oper-
ating the ATV. Parents should decide when to
adjust the ATV for more power as their young-
ster'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 removal of
this plate will result in a significant increase in
power, turn the speed limiter completely back in
again; adjust it out in stages as you did before.
Adjusting for maximum throttle lever movement
without removing the air intake restrictor plate will
cause the engine to run roughly at higher speeds.
