Throttle lever
Once the engine is running, movement of
the throttle lever will increase the engine
speed.
Regulate the speed of the machine by
varying the throttle position. Because the
throttle is spring-loaded, the machine will
decelerate, and the engine will return to an
idle any time the hand is removed from the
throttle lever.
1. Throttle lever
Before starting the engine, check the throt-
tle to be sure it is operating smoothly.
Make sure it returns to the idle position as
soon as the lever is released.
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
before 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.
