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 grad-
ually adjusted to increase maximum speed 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
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.
