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.

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.)

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.

ECB00070
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.

EBU20670
Engine break-in
There is never a more important period in the life of
your engine than the first 20 hours of riding. For
this reason, you should read the following material
carefully.
Since the engine is brand new, do not put an excessive load on it for the first 20 hours. The various
parts in the engine wear and polish themselves to
the correct operating clearances. During this period, prolonged full-throttle operation or any condition that might result in engine overheating must
be avoided.
0–10 hours
Avoid prolonged operation above 1/2 throttle. Vary
the speed of the ATV regularly. Do not operate it at
one set throttle position.
10–20 hours
Avoid prolonged operation above 3/4 throttle. Rev
the engine through the gears freely, but do not use
full throttle at any time.

Accessories and loading
EBU20920
Accessories
Accessories can affect the handling and control of
your ATV. Keep the following in mind when considering an accessory or operating an ATV which has
accessories.
●
Choose only accessories designed for your
ATV. Your Yamaha dealer has a variety of genuine Yamaha accessories. Other accessories
may also be available on the market. However,
it is not possible for Yamaha to test all nonYamaha accessories, nor control over their quality or suitability. Choose a genuine Yamaha accessory, or one that is equivalent in design and
quality.
●
Accessories should be rigidly and securely
mounted. An accessory which can shift position
or come off while you are riding could affect your
ability to control the ATV.
●
Do not mount an accessory where it could interfere with your ability to control the ATV. Examples include (but are not limited to) a heavy or
bulky object attached to the handlebars which
could make steering difficult, an accessory that

EBU21110
Loading
As originally equipped, this ATV is not designed to
4
tow a trailer. If you choose to add accessories so
5
that you can tow a trailer, you must use common
sense and good judgment as the stability and han-
6
dling of an ATV can be changed. When adding accessories, keep the following points in mind:
7
●
Never exceed the weight limits shown. An overloaded ATV can be unstable.

11
ATV loading limit (total weight of rider, cargo,
accessories, and tongue):
95.0 kg (209 lb)
Carrier:
5.0 kg (11 lb)
●
If you are carrying cargo and towing a trailer, include the tongue weight in the maximum ATV
load limit.
●
Load cargo on the carrier as close to the center
of the ATV as possible. Put cargo at the front of
the carrier and center it.
●
Tie down cargo securely to the carrier. Make
sure cargo in the trailer cannot move around. A
shifting load can cause an accident.
●
Make sure the load does not interfere with controls or your ability to see where you are going.
●
Ride more slowly than you would without a load.
The more weight you carry, the slower you
should go. Although conditions vary, it is good
practice not to exceed 2nd gear whenever you
are carrying heavier loads or when towing a trailer.
●
Allow more braking distance. A heavier ATV
takes longer to stop.
●
Avoid making sharp turns unless at very slow
speeds.
●
Avoid hills and rough terrain. Choose terrain
carefully. Added weight affects the stability and
6-8
handling of the ATV.

WARNING
POTENTIAL HAZARD
Operating this ATV at speeds too fast for
your skills or the conditions.
WHAT CAN HAPPEN
Increases your chances of losing control of
the ATV, which can result in an accident.
HOW TO AVOID THE HAZARD
Always go at a speed that is proper for the
terrain, visibility and operating conditions,
and your experience.
Speed limiter
For riders less experienced with this model, the
throttle lever housing is equipped with a speed limiter. The speed limiter keeps the throttle from fully
opening, even when the throttle lever is pushed to
the maximum. Turning in the adjusting screw limits
the maximum engine power available and decreases the maximum speed of the ATV. Turning
in the adjusting screw decreases top speed, and
turning it out increases top speed. (See page 4-4.)
This model also has an air intake restrictor plate to
limit the amount of engine power available.
Yamaha recommends that all beginning riders
start off with the speed limiter turned in and the air
intake restrictor plate installed to limit the amount
of speed available while they learn. The limiter may
be gradually adjusted 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.
Adjusting for maximum throttle lever movement
without removing the air intake restrictor plate will
cause the engine to run roughly at higher speeds.

WARNING
POTENTIAL HAZARD
Operating in areas where you might not be
seen by other off-road vehicles.
WHAT CAN HAPPEN
You could be in a collision. You could be injured.
HOW TO AVOID THE HAZARD
Always mount a caution flag on the ATV to
make you more visible. Watch carefully for
other vehicles.
Select a large, flat area off-road to become familiar
with your ATV. Make sure that this area is free of
obstacles and other riders. You should practice
control of the throttle, brakes, shifting procedures,
and turning techniques in this area before trying
more difficult terrain. Always avoid riding on paved
surfaces: the ATV is designed for off-road use
only, and handling maneuvers are more difficult to
perform on pavement.
Set the parking brake and follow the instruction on
page 6-1 to start the engine. Once it has warmed
up you are ready to begin riding your ATV. As you
get on the ATV, be sure not to accidentally move
7-16

the shift pedal. Remember that the engine and exhaust pipe will be hot when riding and afterwards;
1
do not allow skin or clothing to come in contact with
these components.
2
With the engine idling, lift the shift pedal to the 1st
gear position and then release the parking brake.
3
Apply the throttle slowly and smoothly. The centrifugal clutch will engage and you will start to accel-
4
erate. Once the ATV has attained adequate
speed, release the throttle and lift the shift pedal to
5
the 2nd gear position. Release the shift pedal and
apply the throttle smoothly. Use this same proce-
6
dure as you move into the higher gears. Be sure to
coordinate the use of the throttle and shift pedal
7
properly. If the throttle is applied too abruptly or if
the throttle is not released during shifting, or if the
8
shift pedal is not released before applying the
9
throttle, the front wheels may lift off the ground, resulting in a loss of directional control. Avoid higher
10
speeds until you are thoroughly familiar with the
operation of your ATV.
11
ECB00230
CAUTION:
Do not shift gears without releasing the throttle. Damage to the engine or drive train may occur.
When slowing down or stopping, release the throttle and apply the brakes smoothly and evenly. As
you slow down, shift to a lower gear. Be sure that
the engine has sufficiently slowed before engaging
a lower gear. Improper use of the brakes or shifting
can cause the tires to lose traction, reducing control and increasing the possibility of an accident.
EWB01070
WARNING
POTENTIAL HAZARD
Engaging a lower gear when the engine
speed is too high.
WHAT CAN HAPPEN
The wheels could stop rotating. This could
cause loss of control, an accident and injury.
It could also cause engine or drive train damage.
HOW TO AVOID THE HAZARD
Make sure the engine has sufficiently slowed
before shifting to a lower gear.
TURNING YOUR ATV
To achieve maximum traction while riding off-road,
the two rear wheels are mounted solidly on one
axle and turn together at the same speed. Therefore, unless the wheel on the inside of the turn is al-
7-17
lowed to slip or lose some traction, the ATV will
resist turning. A special turning technique must be
used to allow the ATV to make turns quickly and
easily. It is essential that this skill be learned first at
low speed.
EWB01220
WARNING
POTENTIAL HAZARD
Turning improperly.
WHAT CAN HAPPEN
The ATV could go out of control, causing a
collision or overturn.
HOW TO AVOID THE HAZARD
Always follow proper procedures for turning
as described in this Owner’s Manual. Practice turning at low speeds before attempting
to turn at faster speeds. Do not turn at
speeds too fast for your skills or the conditions.
As you approach a curve, slow down and begin to
turn the handlebars in the desired direction. As you
do so, put your weight on the footboard to the outside of the turn (opposite your desired direction)
and lean your upper body into the turn. Use the
throttle to maintain an even speed through the
turn. This maneuver will let the wheel on the inside
of the turn slip slightly, allowing the ATV to make
the turn properly.
1
2
1. Lean towards inside of turn.
2. Support your weight on the outer footboard.
This procedure should be practiced at slow speed
many times in a large off-road area with no obstacles. If an incorrect technique is used, your ATV
may continue to go straight. If the ATV doesn’t
turn, come to a stop and then practice the procedure again. If the riding surface is slippery or loose,
it may help to position more of your weight over the
front wheels by moving forward on the seat.

changes, excessive braking, incorrect body movements, or too much speed for the sharpness of the
3
turn may cause the ATV to tip. If the ATV begins to
tip over to the outside while negotiating a turn, lean
4
more to the inside. It may also be necessary to
gradually let off on the throttle and steer to the out-
5
side of the turn to avoid tipping over.
Remember: Avoid higher speeds until you are
6
thoroughly familiar with the operation of your ATV.

CLIMBING UPHILL
Use proper riding techniques to avoid ATV over-
8
turns on hills. Be sure that you can maneuver your
ATV well on flat ground before attempting any in-
9
cline and then practice riding first on gentle slopes.
10
Try more difficult climbs only after you have developed your skill. In all cases avoid inclines with slip-
11
pery or loose surfaces, or obstacles that might
cause you to lose control.
EWB01090
WARNING
POTENTIAL HAZARD
Operating on excessively steep hills.
WHAT CAN HAPPEN
The ATV can overturn more easily on extremely steep hills than on level surfaces or
small hills.
HOW TO AVOID THE HAZARD
Never operate the ATV on hills too steep for
the ATV or for your abilities. Practice on
smaller hills before attempting large hills.
It is important when climbing a hill to make sure
that your weight is transferred forward on the ATV.
This can be accomplished by leaning forward and,
on steeper inclines, standing on the footboards
and leaning forward over the handlebars.
EWB01100
WARNING
POTENTIAL HAZARD
Climbing hills improperly.
WHAT CAN HAPPEN
Could cause loss of control or cause the ATV

Shift your weight forward.
Never open the throttle suddenly or make
sudden gear changes. The ATV could flip
over backwards.
Never go over the top of any hill at high
speed. An obstacle, a sharp drop, or another
vehicle or person could be on the other side
of the hill.
If you are climbing a hill and you find that you have
not properly judged your ability to make it to the
top, you should turn the ATV around while you still
have forward motion (provided you have the room
to do so) and go down the hill.

●
as well, and then lock the parking brake.
Dismount on uphill side or to a side if pointed
straight uphill. Turn the ATV around and remount, following the procedure described in
the Owner’s Manual.
RIDING DOWNHILL
When riding your ATV downhill, shift your weight
as far to the rear and uphill side of the ATV as possible. Move back on the seat and sit with your arms
straight. Choose a low gear which will allow the engine compression to do most of the braking for
you. Improper braking may cause a loss of traction.
Use caution while descending a hill with loose or
slippery surfaces. Braking ability and traction may
be adversely affected by these surfaces. Improper
braking may also cause a loss of traction.
Whenever possible, ride your ATV straight downhill. Avoid sharp angles which could allow the ATV

CROSSING A SLOPE
Traversing a sloping surface on your ATV requires
you to properly position your weight to maintain
proper balance. Be sure that you have learned the
basic riding skills on flat ground before attempting
to cross a sloping surface. Avoid slopes with slippery surfaces or rough terrain that may upset your
balance.
As you travel across a slope, lean your body in the
uphill direction. It may be necessary to correct the
steering when riding on loose surfaces by pointing
7-23
the front wheels slightly uphill. When riding on
slopes, be sure not to make sharp turns either up
or down hill.
If your ATV does begin to tip over, gradually steer
in the downhill direction if there are no obstacles in
your path. As you regain proper balance, gradually
steer again in the direction you wish to travel.

pery surfaces since the ATV may slide. If unexpected and uncorrected, sliding could lead to an
10
accident.
To reduce the tendency for the front wheels to slide
11
in loose or slippery conditions, positioning your
weight over the front wheels will sometimes help.
If the rear wheels of your ATV start to slide sideways, control can usually be regained (if there is
room to do so) by steering in the direction of the
slide. Applying the brakes or accelerating is not
recommended until you have corrected the slide.
7-27
WHAT CAN HAPPEN
You may lose control of this ATV. You may
also regain traction unexpectedly, which
may cause the ATV to overturn.
HOW TO AVOID THE HAZARD
Learn to safely control skidding or sliding by
practicing at low speeds and on level,
smooth terrain.
On extremely slippery surfaces, such as ice,
go slowly and be very cautious in order to reduce the chance of skidding or sliding out of
control.

to the outside of the turn. (See page 7-17.)
●
If your ATV starts to slide sideways:
2
Steer in the direction of the slide if you have the
room. Applying the brakes or accelerating is not
3
recommended until you have corrected the
slide. (See page 7-27.)
4
●
If your ATV can’t make it up a hill you are trying
to climb:
5
Turn the ATV around if you still have forward
speed. If not, stop, dismount on the uphill side of
6
the ATV and physically turn the ATV around. If
the ATV starts to slip backwards, DO NOT USE
7
THE REAR BRAKE – the ATV may tip over on
top of you. Instead, apply the front brake or dis-
8
mount the ATV on the uphill side. (See
9
page 7-19.)
●
If your ATV is traversing a sloping surface:
Be sure to ride with your weight positioned towards the uphill side of the ATV to maintain
proper balance. If the ATV starts to tip, steer
down the hill (if there are no obstacles in your
way) to regain balance. If you discover that the
ATV is going to tip over, dismount on the uphill
side. (See page 7-19.)
●
If your ATV encounters shallow water:
Ride slowly and carefully through slow moving
water, watching for obstacles. Be sure to let water drain from the ATV and CHECK YOUR
BRAKES FOR PROPER OPERATION when
you come out of the water. Do not continue to
ride your ATV until you have regained adequate
braking ability. (See page 7-24.)
