dures. If you have any questions regarding the operation or maintenance of your ATV, please consult a
Yamaha dealer.
AN IMPORTANT SAFETY MESSAGE:
●
READ THIS MANUAL TOGETHER WITH TIPS FOR THE ATV RIDER CAREFULLY AND COMPLETELY BEFORE OPERATING YOUR ATV. MAKE SURE YOU UNDERSTAND ALL INSTRUCTIONS.
●
PAY CLOSE ATTENTION TO THE WARNING AND CAUTION LABELS ON THE ATV.
●
NEVER OPERATE AN ATV WITHOUT PROPER TRAINING OR INSTRUCTION. FREE TRAINING IS
AVAILABLE TO ANYONE WHO BUYS A NEW ATV. CALL 1-800-887-2887 FOR MORE INFORMATION.

THIS ATV, AND ANY OTHER ATV OVER 70 cc, SHOULD NOT BE OPERATED BY A CHILD UNDER
12 YEARS OF AGE.
It also includes basic maintenance and inspection proce-
AN IMPORTANT NOTE TO PARENTS:
This ATV is not a toy. Before you let your child ride this ATV, you should understand the instructions and
warnings in this Owner’s Manual. Then be sure your child understands and will follow them. Children differ
in skills, physical abilities and judgment. Some children may not be able to operate an ATV safely. Parents
should supervise their child’s use of the ATV at all times. Parents should permit continued use only if they
determine that the child has the ability to operate the ATV safely.
Your ATV was delivered with an adjustable speed limiter and also with an air intake restrictor plate. Yamaha
recommends that all beginners 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 back in again; adjust it out in stages as you did before.
If your child is a beginner or is inexperienced, he or she should take a training course. See the previous
page for information about the free training available to purchasers of new ATVs.

Once the engine is running, movement of the throttle lever will increase the engine speed.
Regulate the speed of the ATV by varying the
throttle position. Because the throttle is springloaded, the ATV will decelerate, and the engine will
return to an idle any time the hand is removed from
the throttle lever.

HOW TO AVOID THE HAZARD
Check the operation of the throttle lever be-

Speed limiter and air intake restrictor

plate
10
Your ATV was delivered with an adjustable speed
limiter and an air intake restrictor plate. Yamaha
11
recommends that all beginning riders start off with
the speed limiter adjusting screw fully turned in and
the air intake restrictor plate installed to limit the
amount of speed available while they learn.
The speed limiter keeps the throttle from fully
opening, even when the throttle lever is pushed to
the maximum. The adjusting screw may be gradually turned out 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 adjusting screw
completely back in again; adjust it out in stages as
done previously.
1. Loosen the locknut.
2. To increase the maximum engine power available and the maximum speed of the ATV, turn
the adjusting screw in direction (a). To decrease the maximum engine power available
and the maximum speed of the ATV, turn the
adjusting screw in direction (b).
NOTE:
Adjusting for maximum throttle lever movement
without removing the air intake restrictor plate will
cause the engine to run roughly at higher speeds.
(See page 8-18.)

HOW TO AVOID THE HAZARD
Do not turn the adjusting screw out more
than 20 mm (0.8 in).

WARNING
POTENTIAL HAZARD
Improper use of the parking brake.
WHAT CAN HAPPEN
The ATV could start moving unexpectedly if
the parking brake is not applied before starting the engine. This could cause loss of control or a collision.
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.
HOW TO AVOID THE HAZARD
Always set the parking brake before starting
the engine.
Always be sure you have released the parking brake before you begin to ride.

CAUTION:
Use only unleaded gasoline. The use of leaded
gasoline will cause severe damage to internal
engine parts, such as the valves and piston
Your Yamaha engine has been designed to use
regular unleaded gasoline with a pump octane
number [(R+M)/2] of 86 or higher, or a research octane number of 91 or higher. If knocking or pinging
occurs, use a different brand of gasoline or premium unleaded fuel. Unleaded fuel will give you longer spark plug life and reduced maintenance cost.
Gasohol
There are two types of gasohol: gasohol containing ethanol and that containing methanol. Gasohol
containing ethanol can be used if the ethanol content does not exceed 10%. Gasohol containing
methanol is not recommended by Yamaha because it can cause damage to the fuel system or
ATV performance problems.
