Throttle lever
Once the engine is running, movement of the throt-
tle lever will increase the engine speed.
Regulate the speed of the ATV by varying the
throttle position. Because the throttle is spring-
loaded, the ATV will decelerate, and the engine will
return to an idle any time the hand is removed from
the throttle lever.
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.
Speed limiters
Your ATV was delivered with two speed limiter
devices. A vehicle speed limiter adjusting screw
and a removable engine speed limiter plate.
Yamaha recommends that all beginning riders start
off with the vehicle speed limiter adjusting screw fully
turned in and the engine speed limiter plate installed
to limit the amount of speed available while they learn.

WARNING
POTENTIAL HAZARD
Malfunction of throttle.
WHAT CAN HAPPEN
The throttle could be hard to operate, making
it difficult to speed up or slow down when
you need to. This could cause an accident.
HOW TO AVOID THE HAZARD
Check the operation of the throttle lever be-
fore you start the engine. If it does not work
smoothly, check for the cause. Correct the
problem before riding the ATV. Consult a
Yamaha dealer if you can’t find or solve the
problem yourself.
