G Always follow proper procedures for turning as described in this manual. Practice turning at low
speeds before attempting to turn at faster speeds. Do not turn at excessive speed.
G Never operate the ATV on hills too steep for the ATV or for your abilities. Practice on smaller
hills before attempting larger hills.
G Always follow proper procedures for climbing hills as described in this manual. Check the ter-
rain carefully before you start up any hill. Never climb hills with excessively slippery or loose
surfaces. Shift your weight forward. Never open the throttle suddenly or make sudden gear
changes. Never go over the top of a hill at high speed.
G Always follow proper procedures for going down hills and for braking on hills as described in
this manual. Check the terrain carefully before you start down any hill. Shift your weight back-
ward. Never go down a hill at high speed. Avoid going down a hill at an angle that would cause
the vehicle to lean sharply to one side. Go straight down the hill where possible.
G Always follow proper procedures for crossing the side of a hill as described in this manual.
Avoid hills with excessively slippery or loose surfaces. Shift your weight to the uphill side of the
ATV. Never attempt to turn the ATV around on any hill until you have mastered the turning

G Always use proper procedures if you stall or roll backwards when climbing a hill. To avoid stall-
ing, use proper gear and maintain a steady speed when climbing a hill. If you stall or roll back-
wards, follow the special procedure for braking described in this manual. Dismount on the
uphill side or to a side if pointed straight uphill. Turn the ATV around and remount, following the
procedure described in this manual.
G Always check for obstacles before operating in a new area.
Never attempt to operate over large obstacles, such as large rocks or fallen trees. Always fol-
low proper procedures when operating over obstacles as described in this manual.
G Always be careful when skidding or sliding. Learn to safely control skidding or sliding by prac-
ticing 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 con-
trol.
G Never operate an ATV in fast flowing water or in water deeper than that recommended in this
manual. Remember that wet brakes may have reduced stopping ability. Test your brakes after
leaving water. If necessary, apply them several times to let friction dry out the linings.
G Always be sure there are no obstacles or people behind you when you operate in reverse.
When it is safe to proceed in reverse, go slowly.

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 le-
ver is released.
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.
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.

Speed limiter
WARNING
The speed limiter keeps the throttle from fully
opening, even when the throttle lever is
pushed to the maximum. Turning in the ad-
justing screw limits the maximum engine pow-
er available and decreases the maximum
speed of the ATV.
POTENTIAL HAZARD
Improper adjustment of the speed limit-
er and throttle.
WHAT CAN HAPPEN
The throttle cable could be damaged.
Improper throttle operation could result.
You could lose control, have an acci-
dent or be injured.
HOW TO AVOID THE HAZARD
Do not turn the adjusting screw out
more than 12 mm (0.47 in). Always make
sure the throttle lever free play is adjust-
ed to 3–5 mm (0.12–0.20 in). See page

Gasohol
WARNING
There are two types of gasohol; gasohol con-
taining ethanol and that containing methanol.
Gasohol containing ethanol can be used if
ethanol content does not exceed 10%. Gaso-
hol containing methanol is not recommended
by Yamaha because it may cause fuel system
damage or vehicle performance problems.
POTENTIAL HAZARD
Improper care when refueling.
WHAT CAN HAPPEN
Fuel can spill, which can cause a fire
and severe injury.
Fuel expands when it heats up. If the
fuel tank is overfilled, fuel could spill out
due to heat from the engine or the sun.
HOW TO AVOID THE HAZARD
Do not overfill the fuel tank. Be careful
not to spill fuel, especially on the engine
or exhaust pipe. Wipe up any spilled fuel
immediately. Be sure the fuel tank cap is
closed securely.

Engine break-in
Each full throttle acceleration sequence
should be followed with a substantial rest pe-
riod for the engine by cruising at lower r/min
so the engine can rid itself of the temporary
build up of heat.
If any abnormality is noticed during this peri-
od, consult a Yamaha dealer.
1. 0–10 hours:
There is never a more important period in the
life of your machine than the period between
zero and 20 hours.
For this reason, we ask that you carefully read
the following material. Because the engine is
brand new, you must not put an excessive
load on it for the first several hours of running.
During 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 oper-
ation or any condition which might result in ex-
cessive engine heating must be avoided.
However, momentary (2–3 seconds maxi-
mum) full throttle operation under load does
not harm the engine.
Avoid continuous operation above half
throttle. Allow a cooling off period of five
to ten minutes after every hour of opera-
tion. Vary the speed of the machine from
time to time. Do not operate it at one set
throttle position.
2. 10–20 hours:
Avoid prolonged operation above 3/4
throttle. Rev the machine freely through
the gears but do not use full throttle at
any time.
3. After break-in:
Avoid prolonged full throttle operation.
Vary speeds occasionally.

trol of your ATV. Keep the following in mind
when considering an accessory or operating
an ATV which has accessories.
G Choose only accessories designed for your
ATV. Your Yamaha dealer has a variety of
genuine Yamaha accessories. Other ac-
cessories may also be available on the
market. However, it is not possible for
Yamaha to test all non-Yamaha accesso-
ries, nor have any control over the quality or
suitability of them. Choose a genuine
Yamaha accessory, or one that is equiva-
lent in design and quality.
G Use extra caution when riding an ATV with
accessories. The ATV may handle differ-
ently than it does without accessories.
G Accessories should be rigidly and securely
mounted. An accessory which can shift po-
sition or come off while you are riding could
affect your ability to control the ATV.

Loading
G Tie down cargo securely to the carriers.
Make sure cargo in the trailer cannot move
around. A shifting load can cause an acci-
dent.
G Make sure the load does not interfere with
controls or your ability to see where you are
going.
As originally equipped, this ATV is not de-
signed to carry cargo or tow a trailer. If you
choose to add accessories so that you can
carry cargo or tow a trailer, you must use
common sense and good judgment. Keep the
following points in mind:
G Never exceed the weight limits shown. An
overloaded ATV can be unstable.
G Ride more slowly than you would without a
load. The more weight you carry, the slow-
er 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.
G Allow more braking distance. A heavier ve-
hicle takes longer to stop.
G Avoid making sharp turns unless at very
slow speeds.
MAXIMUM LOADING LIMIT
Vehicle loading limit (total weight of
cargo, rider and accessories):
100 kg (220 lb)
G Load cargo on the carriers as close to the
center of the vehicle as possible. Put cargo
at the rear of the front carrier and at the
front of the rear carrier. Center the load
from side to side.
G Avoid hills and rough terrain. Choose ter-
rain carefully. Added weight affects the sta-
bility and handling of the ATV.

Select a large, flat area off-road to become fa-
miliar 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. Al-
ways avoid riding on paved surfaces: the ATV
is designed for off-road use only, and han-
dling maneuvers are more difficult to perform
on pavement.
With the engine idling, pull the clutch lever to
disengage the clutch and shift into 1st gear,
and then release the parking brake. Open the
throttle gradually, and at the same time, re-
lease the clutch lever slowly. Once the ATV
has attained adequate speed, release the
throttle lever and at the same time, quickly pull
in the clutch lever and shift into 2nd gear.
Open the throttle part way and gradually re-
lease the clutch. Use this same procedure as
you move into the higher gears. Be sure to co-
ordinate the use of the throttle and shift pedal
properly. If the throttle is applied too abruptly
or if the throttle is not released during shifting,
or if the shift pedal is not released before ap-
plying the throttle, the front wheels may lift off
the ground resulting in a loss of directional
control. Avoid higher speeds until you are
thoroughly familiar with the operation of your
ATV.
Set the parking brake and follow the instruc-
tions 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 the shift pedal. Remem-
ber that the engine and exhaust pipe will be
hot when riding and afterwards; do not allow
skin or clothing to come in contact with these
components.

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. Improp-
er use of the brakes or shifting can cause the
tires to lose traction, reducing control and in-
creasing the possibility of an accident.
WARNING
POTENTIAL HAZARD
Opening the throttle abruptly or releas-
ing the clutch lever to quickly.
WHAT CAN HAPPEN
The ATV could wheelie. This would in-
crease the chance of an accident, in-
cluding overturn.
HOW TO AVOID THE HAZARD
Open the throttle gradually. Release the
clutch lever gradually.
WARNING
POTENTIAL HAZARD
Engaging a lower gear when the engine
speed is too high.
CAUTION:
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.
Do not shift gears without releasing the
throttle. Damage to the engine or drive
train may occur.

HOW TO AVOID THE HAZARD
Make sure the engine has sufficiently
slowed before shifting to a lower gear.

TURNING YOUR ATV
HOW TO AVOID THE HAZARD
Always follow proper procedures for
turning as described in this Owner’s
Manual.
Practice turning at low speeds before at-
tempting to turn at faster speeds. Do not
turn at speeds too fast for your skills or
the conditions.
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 in-
side of the turn is allowed 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 es-
sential that this skill be learned first at low
speed.
As you approach a curve, slow down and be-
gin to turn the handlebars in the desired direc-
tion. 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 maneu-
ver will let the wheel on the inside of the turn
slip slightly, allowing the ATV to make the turn
properly.
WARNING
POTENTIAL HAZARD
Turning improperly.
WHAT CAN HAPPEN
The ATV could go out of control, caus-
ing a collision or overturn.
7-23
Download from Www.Somanuals.com. All Manuals Search And Download.
Once you have learned this technique you
should be able to perform it at higher speeds
or in tighter curves.
Improper riding procedures such as abrupt
throttle changes, excessive braking, incorrect
body movements, or too much speed for the
sharpness of the turn may cause the ATV to
tip. If the ATV begins to tip over to the outside
while negotiating a turn, lean more to the in-
side. It may also be necessary to gradually let
off on the throttle and steer to the outside of
the turn to avoid tipping over.
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 sur-
face is slippery or loose, it may help to posi-
tion more of your weight over the front wheels
by moving forward on the seat.
Remember: Avoid higher speeds until you are
thoroughly familiar with the operation of your
ATV.

CLIMBING UPHILL
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 attempt-
ing large hills.
Use proper riding techniques to avoid vehicle
overturns on hills. Be sure that you can ma-
neuver your ATV well on flat ground before at-
tempting any incline and then practice riding
first on gentle slopes. Try more difficult climbs
only after you have developed your skill. In all
cases avoid inclines with slippery or loose sur-
faces, or obstacles that might cause you to
lose control.
It is important when climbing a hill to make
sure that your weight is transferred forward on
the ATV. This can be accomplished by lean-
ing forward and, on steeper inclines, standing
on the footboards and leaning forward over
the handlebars.

RIDING DOWNHILL
WARNING
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 trac-
tion may be adversely affected by these sur-
faces. Improper braking may also cause a
loss of traction.
POTENTIAL HAZARD
Going down a hill improperly.
WHAT CAN HAPPEN
Could cause loss of control or cause the
ATV to overturn.
HOW TO AVOID THE HAZARD
Always follow proper procedures for go-
ing down hills as described in this Own-
er’s Manual. Note: a special technique is
required when braking as you go down
a hill.
Always check the terrain carefully be-
fore you start down any hill.
Shift your weight backward. Never go
down a hill at high speed.
Whenever possible, ride your ATV straight
downhill. Avoid sharp angles which could al-
low the ATV to tip or roll over. Carefully
choose your path and ride no faster than you
will be able to react to obstacles which may
appear.
Avoid going down a hill at an angle that
would cause the vehicle to lean sharply
to one side. Go straight down the hill
where possible.

RIDING OVER ROUGH TERRAIN
WARNING
Riding over rough terrain should be done with
caution. Look out for obstacles which could
cause damage to the ATV or could lead to an
upset or accident. Be sure to keep your feet
firmly mounted on the footboards at all times.
Avoid jumping the ATV as loss of control and
damage to the ATV may result.
POTENTIAL HAZARD
Improperly operating over obstacles.
WHAT CAN HAPPEN
Could cause loss of control or a colli-
sion. Could cause the ATV to overturn.
HOW TO AVOID THE HAZARD
Before operating in a new area, check
for obstacles.

SLIDING AND SKIDDING
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 direc-
tion of the slide. Applying the brakes or accel-
erating is not recommended until you have
corrected the slide.
Care should be used when riding on loose or
slippery surfaces since the ATV may slide. If
unexpected and uncorrected, sliding could
lead to an accident.
To reduce the tendency for the front wheels to
slide in loose or slippery conditions, position-
ing your weight over the front wheels will
sometimes help.
7-38
Download from Www.Somanuals.com. All Manuals Search And Download.
With practice, over a period of time, skill at
controlled sliding can be developed. The ter-
rain should be chosen carefully before at-
tempting such maneuvers, since both stability
and control are reduced. Bear in mind that
sliding maneuvers should always be avoided
on extremely slippery surfaces such as ice,
since all control may be lost.
WARNING
POTENTIAL HAZARD
Skidding or sliding improperly.
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 slid-
ing 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.

WHAT TO DO IF ...
G If your ATV starts to slide sideways:
Steer in the direction of the slide if you have
the room.
This section is designed to be a reference
guide only. Be sure to read each section on
riding techniques completely.
Applying the brakes or accelerating is not
recommended until you have corrected the
slide. (See pages 7-38–7-39.)
WHAT TO DO ...
G If your ATV doesn’t turn when you want it
to:
G If your ATV can’t make it up a hill you are
trying to climb:
Bring the ATV to a stop and practice the
turning maneuvers again. Be sure you are
putting your weight on the footboard to the
outside of the turn. Position your weight
over the front wheels for better control.
(See pages 7-23–7-24.)
Turn the ATV around if you still have for-
ward speed. If not, stop, dismount on the
uphill side of the ATV and physically turn
the ATV around. If the ATV starts to slip
backwards DO NOT USE THE REAR
BRAKE - the ATV may tip over on top of
you. Dismount the ATV on the uphill side.
(See pages 7-25–7-29.)
G If your ATV begins to tip while turning:
Lean more into the turn to regain balance. If
necessary, gradually let off the throttle and/
or steer to the outside of the turn. (See pag-
es 7-23–7-24.)
7-40
Download from Www.Somanuals.com. All Manuals Search And Download.
G If your ATV is traversing a sloping surface:
Be sure to ride with your weight positioned
towards the uphill side of the ATV to main-
tain 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 dis-
cover that the ATV is going to tip over, dis-
mount on the uphill side. (See pages 7-32–
7-33.)
G 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 un-
til you have regained adequate braking
ability. (See pages 7-34–7-35.)

Inspection
The spark plug is an important engine compo-
nent and is easy to inspect. The condition of
the spark plug can indicate the condition of
the engine.
The ideal color on the white insulator around
the center electrode is a medium-to-light tan
color for a ATV that is being ridden normally.
Do not attempt to diagnose such problems
yourself.
Instead, take the ATV to a Yamaha dealer.
You should periodically remove and inspect
the spark plug because heat and deposits will
cause the spark plug to slowly break down
and erode. If electrode erosion becomes ex-
cessive, or if carbon and other deposits are
excessive, you should replace the spark plug
with the specified plug.

Insufficient brake fluid may let air enter the
brake system, possibly causing the brakes to
become ineffective.
Before riding, check that the brake fluid is
above the minimum level mark and replenish
if necessary. A low brake fluid level may indi-
cate worn brake pads and/or brake system
leakage. If the brake fluid level is low, be sure
to check the brake pads for wear and the
brake system for leakage.

Troubleshooting
WARNING
Although Yamaha machines receive a rigid in-
spection before shipment from the factory,
trouble may occur during operation. Any prob-
lem in the fuel, compression, or ignition sys-
tems can cause poor starting and loss of
power. The troubleshooting chart describes a
quick, easy procedure for making checks. If
your machine requires any repair, take it to a
Yamaha dealer.
The skilled technicians at a Yamaha dealer-
ship have the tools, experience, and know-
how to properly service your machine. Use
only genuine Yamaha parts on your machine.
Imitation parts may look like Yamaha parts,
but they are often inferior. Consequently, they
have a shorter service life and can lead to ex-
pensive repair bills.
POTENTIAL HAZARD
Checking the fuel system while smok-
ing or near an open flame.
WHAT CAN HAPPEN
Fuel can ignite or explode, causing se-
vere injury or property damage.
HOW TO AVOID THE HAZARD
Do not smoke when checking the fuel
system. Make sure there are no open
flames or sparks in the area, including
pilot lights from water heaters or furnac-
es.

CLEANING AND STORAGE
CAUTION:
1
Excessive water pressure may cause wa-
ter seepage and deterioration of wheel
bearings, brakes, transmission seals and
electrical devices. Many expensive repair
bills have resulted from improper high
pressure detergent applications such as
those available in coin-operated car wash-
ers.
A. CLEANING
2
Frequent, thorough cleaning of your machine
will not only enhance its appearance but will
improve its general performance and extend
the useful life of many components.
1. Before cleaning the machine:
a. Block off the end of the exhaust pipe to
prevent water entry. A plastic bag and
strong rubber band may be used.
b. Make sure the spark plug and all filler
caps are properly installed.
2. If the engine case is excessively greasy,
apply degreaser with a paint brush. Do
not apply degreaser to the chain, sprock-
ets or wheel axles.
3. Rinse the dirt and degreaser off with a
garden hose. Use only enough pressure
to do the job.

4. Once the majority of the dirt has been
hosed off, wash all surfaces with warm
water and mild, detergent-type soap. An
old toothbrush or bottle brush is handy for
hard-to-get-at places.
5. Rinse the machine off immediately with
clean water and dry all surfaces with a
chamois, clean towel or soft absorbent
cloth.

7. Clean the seat with a vinyl upholstery
cleaner to keep the cover pliable and
glossy.
8. Automotive type wax may be applied to
all painted and chrome plated surfaces.
Avoid combination cleaner-waxes. Many
contain abrasives which may mar the
paint or protective finish. When finished,
start the engine and let it idle for several
minutes.
WARNING
POTENTIAL HAZARD
Operation with wet brakes after wash-
ing.
WHAT CAN HAPPEN
Wet brakes may have reduced stopping
ability, increasing the chance of an acci-
dent.
HOW TO AVOID THE HAZARD
Test the brakes after washing. Apply the
brakes several times at slow speeds to
let friction dry out the linings.

B. STORAGE
2. Remove the spark plug, pour about one
tablespoon of SAE 10W30 or 20W40
motor oil in the spark plug hole and rein-
stall the spark plug. Ground the spark
plug wire and turn the engine over seve-
ral times to coat the cylinder wall with oil.
3. Clean the drive chain thoroughly and lu-
bricate it. (See page 8-36.)
4. Lubricate all control cables.
5. Block up the frame to raise all wheels off
the ground.
6. Tie a plastic bag over the exhaust pipe
outlet to prevent moisture from entering.
7. If storing in a humid or salt-air atmo-
sphere, coat all exposed metal surfaces
with a light film of oil. Do not apply oil to
any rubber parts or the seat cover.
Long term storage (60 days or more) of your
machine will require some preventive proce-
dures to guard against deterioration. After
thoroughly cleaning the machine, prepare for
storage as follows:
1. Fill the fuel tank with fresh fuel and add
the specified amount of Yamaha Fuel
Stabilizer and Conditioner or an equiva-
lent product.
Specified amount:
1 oz of stabilizer to each gallon of fuel
(or 7.5 cc of stabilizer to each liter of
fuel)
NOTE:
Use of fuel stabilizer and conditioner elimi-
nates the need to drain the fuel system. Con-
sult a Yamaha dealer if the fuel system needs
to be drained instead.

8. Remove the battery and charge it. Store
it in a dry place and recharge it once a
month. Do not store the battery in an ex-
cessively warm or cold place (less than
0 °C (30 °F) or more than 30 °C (90 °F)).
NOTE:
