Speed Limiter - Yamaha RAPTOR YFM80WS Owner's Manual

EBU01032

Speed limiter

The speed limiter keeps the throttle from fully
opening, even when the throttle lever is pushed
to the maximum. Screwing in the adjuster limits
the maximum engine power available and
decreases the maximum speed of the ATV.
Your ATV was delivered with an adjustable
speed limiter and also with an air intake restric-
tor plate. Yamaha recommends that all begin-
ners start off with the speed limiter screw turned
in and the air intake restrictor plate installed to
limit the amount of speed available while they
learn. The limiter screw may be gradually turned
out 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.
For air intake restrictor plate removal instruc-
tions, see page 8-13.
