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.
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.
w
Malfunction of the throttle could make it diffi-
cult to speed up or slow down when you
need to. This could cause an accident.
Check the operation of the throttle lever
before you start the engine. If the throttle
does not work smoothly, check for the
cause. Correct the problem before riding the
ATV or consult a Yamaha dealer.

Throttle OverRide System
If during operation, the carburetor or the throttle
cable should malfunction and will not close fully,
take your thumb off the throttle lever.
The throttle override system immediately cuts off
the ignition.
w
Riding with a malfunction increases the
chance for an accident and injury. Make sure
that the cause of the malfunction is correct-
ed before restarting the engine or have the
ATV inspected by a Yamaha dealer.

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.
w
Improper adjustment of the speed limiter and
throttle could cause throttle cable damage or
improper throttle operation. You could lose
control, have an accident or be injured. Do
not turn the speed adjuster out more than 12
mm or the throttle cable could be damaged.
Always make sure the throttle lever free play
is adjusted to 4 ~ 6 mm. See page 8-47.

8Always set the parking brake before start-
ing the engine. The ATV could start mov-
ing unexpectedly if the parking brake is
not applied. This could cause loss of con-
trol or a collision.
8Always be sure you have released the
parking brake before you begin to ride.
The brake could overheat if you ride the
ATV without releasing the parking brake.
You could lose braking performance
which could cause an accident. You could
also wear out the brakes prematurely.
