WARNING
EWB00010
Indicates a potential hazard that could result in
serious injury or death.
Do not operate at speeds too fast for your
skills or the conditions.
EWB00960
Speed limiter
For riders less experienced with this model, the
throttle lever housing is equipped with a speed lim-
iter. The speed limiter keeps the throttle from fully
opening, even when the throttle lever is pushed to
the maximum. Turning in the adjusting screw limits
the maximum engine power available and de-
creases the maximum speed of the ATV. Turning
in the adjusting screw decreases top speed, and
turning it out increases top speed. (See page 4-4.)
This model also has an air intake restrictor plate to
limit the amount of engine power available.
Yamaha recommends that all beginning riders
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 ad-
just the ATV for more power as their youngster’s
riding skills improve. Once the ATV rider can oper-
ate with skill at the top speed permitted by adjust-
ing 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 back in again; adjust it out in stag-
es 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.
