SAFETY INFORMATION
1
G Never allow a child under age 16 to operate an
ATV without adult supervision, and never allow
continued use of an ATV by a child if he or she
does not have the abilities to operate it safely.
G Never carry a passenger on an ATV.
G Always avoid operating an ATV on any paved
surfaces, including sidewalks, driveways, park-
ing lots and streets.
AN ATV IS NOT A TOY AND CAN BE HAZARD-
OUS TO OPERATE.
An ATV handles differently from other vehicles, in-
cluding motorcycles and cars. A collision or roll-
over can occur quickly, even during routine
maneuvers such as turning and riding on hills or
over obstacles, if you fail to take proper precau-
tions.
G Never operate an ATV on any public street, road
or highway, even a dirt or gravel one.
SEVERE INJURY OR DEATH can result if you do
not follow these instructions:
G Never operate an ATV without wearing an ap-
proved motorcycle helmet that fits properly. You
should also wear eye protection (goggles or face
shield), gloves, boots, a long-sleeved shirt or a
jacket, and long pants.
G Never consume alcohol or drugs before or while
operating this ATV.
G Never operate at speeds too fast for your skills
or the riding conditions. Always go at a speed
that is proper for the terrain, visibility, operating
conditions, and your experience.
G Read this manual and all labels carefully and fol-
low the operating procedures described.
G Never operate an ATV without proper training or
instruction. Take a Training Course. Beginners
should receive training from a certified instruc-
tor. Contact an authorized ATV dealer or call 1-
800-887-2887 to find out about the training
courses nearest you.
G Always follow the age recommendation:
– A child under 16 years old should never oper-
ate an ATV with engine size greater than 90 cc.
G Never attempt wheelies, jumps, or other stunts.
1-1

G Always inspect your ATV each time you use it to
make sure it is in safe operating condition. Al-
ways follow the inspection and maintenance
procedures and schedules described in this
manual.
G Always keep both hands on the handlebars and
both feet on the footboards of the ATV during
operation.
G Always go slowly and be extra careful when op-
erating on unfamiliar terrain. Always be alert to
changing terrain conditions when operating the
ATV.
G Never operate on excessively rough, slippery or
loose terrain until you have learned and prac-
ticed the skills necessary to control the ATV on
such terrain. Always be especially cautious on
these kinds of terrain.
G Always follow proper procedures for turning as
described in this manual. Practice turning at low
speeds before attempting to turn at faster
speeds and never turn at excessive speeds.
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 sur-
faces. Shift your weight forward. Never open the
throttle suddenly. 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 backward.
Never go down a hill at high speed. Avoid going
down a hill at an angle that would cause the ve-
hicle 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 sur-
faces. 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 tech-
nique described in this manual on level ground.
Avoid crossing the side of a steep hill if possible.
G Always use proper procedures if you stall or roll
backwards when climbing a hill. Maintain a
steady speed when climbing a hill. If you stall or

roll backwards, follow the special procedure for
braking described in this manual. Dismount on
the uphill side or to a side if pointed straight up-
hill. Turn the ATV around and remount, following
the procedure described in this manual.
G Always check for obstacles before operating in a
new area.
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.
G Always use the size and type of tires specified in
this manual.
1
G Always maintain proper tire pressure as de-
scribed in this manual.
G Never attempt to operate over large obstacles,
such as large rocks or fallen trees. Always follow
proper procedures when operating over obsta-
cles as described in this manual.
G Always be careful when skidding or sliding.
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 re-
duce 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 Never modify an ATV through improper installa-
tion or use of accessories.
G Never exceed the stated load capacity for an
ATV. Cargo should be properly distributed and
securely attached. Reduce speed and follow in-
structions in this manual for carrying cargo or
pulling a trailer. Allow greater distance for brak-
ing.

WHAT CAN HAPPEN
The ATV handles differently in two-wheel
drive than in four-wheel drive in some cir-
cumstances. Changing from two-wheel drive
to four-wheel drive or from four-wheel drive
to two-wheel drive while moving may cause
the ATV to unexpectedly handle differently.
This could distract the operator and in-
crease the risk of losing control and of caus-
ing an accident.

WARNING
ETBhU1r82o70ttle lever
POTENTIAL HAZARD
Changing from two-wheel drive to four-
wheel drive or from four-wheel drive to two-
wheel drive while the ATV is moving.
Once the engine is running, movement of the throt-
tle lever will increase the engine speed.
Regulate the speed of the ATV by varying the
throttle position. Because the throttle is spring-
loaded, the ATV will decelerate, and the engine will
return to an idle any time the hand is removed from
the throttle lever.

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.

WHAT CAN HAPPEN
Fuel can spill, which can cause a fire and se-
vere injury.
CAUTION:
Use only unleaded gasoline. The use of leaded
gasoline will cause severe damage to internal
engine parts, such as the valves and piston
rings, as well as to the exhaust system.
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 ex-
haust pipe. Wipe up any spilled fuel immedi-
ately. Be sure the fuel tank cap is closed
securely.
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 oc-
tane number of 91 or higher. If knocking or pinging
occurs, use a different brand of gasoline or premi-
um unleaded fuel. Unleaded fuel will give you long-
er spark plug life and reduced maintenance cost.

throttle lever housing is equipped with a speed lim-
iter. 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 de-
creases the maximum speed of the ATV. Turning
in the adjusting screw decreases top speed, and
turning it out increases top speed. (See page 4-7.)
Use extra caution when riding the ATV with addi-

TURNING YOUR ATV
To achieve maximum traction while riding off-road,
the two rear wheels turn together at the same
speed. Therefore, unless the wheel on the inside
of the turn is allowed to slip or lose some traction,
the ATV will resist turning. A special turning tech-
nique 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.

WARNING
POTENTIAL HAZARD
Turning improperly.
WHAT CAN HAPPEN
ATV could go out of control, causing a colli-
sion or overturn.
HOW TO AVOID THE HAZARD
Always follow proper procedures for turning
as described in this Owner’s Manual. Prac-
tice turning at low speeds before attempting
to turn at faster speeds. Do not turn at
speeds too fast for your skills or the condi-
tions.
1. Lean towards inside of turn.
2. Support your weight on the outer footboard.
7
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 out-
side 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.
This procedure should be practiced at slow speed
many times in a large off-road area with no obsta-
cles. 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 proce-
dure 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.
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 move-
ments, 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 inside. It may also be necessary to
gradually let off on the throttle and steer to the out-
side of the turn to avoid tipping over.
WHAT CAN HAPPEN
The ATV can overturn more easily on ex-
tremely 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.
Remember: Avoid higher speeds until you are
thoroughly familiar with the operation of your ATV.
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
CLIMBING UPHILL
Use proper riding techniques to avoid ATV over-
turns on hills. Be sure that you can maneuver your
ATV well on flat ground before attempting any in-
cline and then practice riding first on gentle slopes.

oped your skill. In all cases avoid inclines with slip-
pery or loose surfaces, or obstacles that might

CROSSING A SLOPE
HOW TO AVOID THE HAZARD
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 slip-
pery 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
the front wheels slightly uphill. When riding on
slopes, be sure not to make sharp turns either up
or down hill.
Never attempt to turn the ATV around on any

Riding over rough terrain should be done with cau-
tion. Look out for obstacles which could cause
damage to the ATV or could lead to an upset or ac-
cident. 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 re-
sult.

SLIDING AND SKIDDING
Care should be used when riding on loose or slip-
pery surfaces since the ATV may slide. If unex-
pected and uncorrected, sliding could lead to an
accident.
To reduce the tendency for the front wheels to slide
in loose or slippery conditions, positioning your
weight over the front wheels will sometimes help.
With practice, over a period of time, skill at con-
trolled sliding can be developed. The terrain
should be chosen carefully before attempting such
maneuvers, since both stability and control are re-
duced. Bear in mind that sliding maneuvers should
always be avoided on extremely slippery surfaces
7
such as ice, since all control may be lost.
If the rear wheels of your ATV start to slide side-
ways, 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.

WHAT CAN HAPPEN
G If your ATV begins to tip while turning:
Lean more into the turn to regain balance. If nec-
to the outside of the turn. (See page 7-17.)
G If your ATV starts to slide sideways:
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.
Steer in the direction of the slide if you have the
room. Applying the brakes or accelerating is not
recommended until you have corrected the
slide. (See page 7-31.)
G If your ATV can’t make it up a hill you are trying
to climb:
Turn the ATV around if you still have forward
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 IF THE ATV IS IN 2WD –
the ATV may tip over on top of you. Dismount
the ATV on the uphill side. (See page 7-19.)
G If your ATV is traversing a sloping surface:
Be sure to ride with your weight positioned to-
wards 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.)

WHAT TO DO...
G If your ATV doesn’t turn when you want it to:
Bring the ATV to a stop and practice the turning
maneuvers again. Be sure you are putting your

turn. Position your weight over the front wheels
for better control. (See page 7-17.)

The spark plug is an important engine component,
which is easy to check. Since heat and deposits
will cause any spark plug to slowly erode, the spark
plug should be removed and checked in accor-
dance with the periodic maintenance and lubrica-
tion chart. In addition, the condition of the spark
plug can reveal the condition of the engine.

ETBrUo257u30bleshooting
Although Yamaha ATVs receive a thorough in-
spection before shipment from the factory, trouble
may occur during operation. Any problem in the fu-
el, compression, or ignition systems, for example,
can cause poor starting and loss of power.
HOW TO AVOID THE HAZARD
Do not smoke when checking the fuel sys-
tem. Make sure there are no open flames or
sparks in the area, including pilot lights from
water heaters or furnaces.
The following troubleshooting charts represent
quick and easy procedures for checking these vital
systems yourself. However, should your ATV re-
quire any repair, take it to a Yamaha dealer, whose
skilled technicians have the necessary tools, expe-
rience, and know-how to service the ATV properly.
Use only genuine Yamaha replacement parts. Im-
itation parts may look like Yamaha parts, but they
are often inferior, have a shorter service life and
8
can lead to expensive repair bills.

ed from improper high-pressure detergent
applications such as those available in coin-
operated car washers.
Cleaning
Frequent, thorough cleaning of your ATV will not
only enhance its appearance but will improve its
general performance and extend the useful life of
many components.
4. Once most of the dirt has been hosed off,
wash all surfaces with warm water and mild,
detergent-type soap. An old toothbrush or bot-
tle brush is handy for hard-to-reach places.
5. Rinse the ATV off immediately with clean wa-
ter and dry all surfaces with a chamois, clean
towel or soft absorbing cloth.
1. Before cleaning the ATV:
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.
6. Clean the seat with a vinyl upholstery cleaner
to keep the cover pliable and glossy.
2. If the engine case is excessively greasy, apply
degreaser with a paint brush. Do not apply de-
greaser to the wheel axles.
7. 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 protec-
tive finish. When finished cleaning, start the
engine and let it idle for several minutes.

3. Rinse the dirt and degreaser off with a garden
hose. Use only enough pressure to do the job.

stored.
WARNING
POTENTIAL HAZARD
Operation with wet brakes after washing.
WHAT CAN HAPPEN
Wet brakes may have reduced stopping abil-
ity, increasing the chance of an accident.
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.
Long-term
Before storing your ATV for several months:
1. Follow all the instructions in the “Cleaning”
section of this chapter.
2. Turn the fuel cock lever to “OFF”.
3. Drain the carburetor float chamber by loosen-
ing the drain bolt; this will prevent fuel deposits
from building up. Pour the drained fuel into the
fuel tank.
ESBUto259r3a2 ge
4. Fill up the fuel tank and add fuel stabilizer (if
available) to prevent the fuel from deteriorat-
ing.
Short-term
Always store your ATV in a cool, dry place and, if
necessary, protect it against dust with a porous
9
cover.
Specified amount:
ECB00720
7.5 ml of stabilizer to each liter of fuel (or 1 oz
of stabilizer to each gallon of fuel)
CAUTION:
G Storing the ATV in a poorly ventilated room
or covering it with a tarp while it is still wet,
will allow water and humidity to seep in and
cause rust.
5. Perform the following steps to protect the cyl-
inder, piston rings, etc. from corrosion.

°F) or more than 30 °C (90 °F)]. For more in-
formation on storing the battery, see page
8-47.
c. Install the spark plug cap onto the spark
plug, and then place the spark plug on the
cylinder head so that the electrodes are
grounded. (This will limit sparking during
the next step.)
d. Turn the engine over several times with the
starter. (This will coat the cylinder wall with
oil.)
NOTE:
Make any necessary repairs before storing the
ATV.
e. Remove the spark plug cap from the spark
plug, and then install the spark plug and
the spark plug cap.
6. Lubricate all control cables and the pivoting
points of all levers and pedals.
7. Check and, if necessary, correct the tire air
pressure, and then block up the ATV so that
all of its wheels are off the ground. Alternative-
ly, turn the wheels a little every month in order
to prevent the tires from becoming degraded
in one spot.

WARRANTY QUESTIONS AND ANSWERS
CUSTOMER SERVICE
Q. What costs are my responsibility during the warranty period?
A. The customer’s responsibility includes all costs of normal maintenance services,
non-warranty repairs, accident and collision damages, and oil, oil filters, air filters,
spark plugs, and brake shoes.
If your machine requires warranty service, you must take it to any authorized
Yamaha ATV dealer within the continental United States. Be sure to bring
your warranty registration card or other valid proof of the original date of
purchase. If a question or problem arises regarding warranty, first contact
the owner of the dealership. Since all warranty matters are handled at the
dealer level, this person is in the best position to help you. If you are still
not satisfied and require additional assistance, please write:
Q. What are some examples of “abnormal” strain, neglect, or abuse?
A. These terms are general and overlap each other in areas. Specific examples include:
Running the machine out of oil, sustained high rpm, full-throttle, operating the
machine with a broken or damaged part which causes another part to fail, damage
or failure due to improper or careless transportation and or tie-down. If you have
any specific questions on operation or maintenance, please contact your dealer
for advice.

Q. Does the warranty cover incidental costs such as towing or transportation due to
a failure?
A. No. The warranty is limited to repair of the machine itself.
When contacting Yamaha Motor Corporation, U.S.A. don’t forget to include
any important information such as names, addresses, model, V.I.N. (frame
number), dates, and receipts.
Q. May I perform any or all of the recommended maintenance shown in the Owner’s
Manual instead of having the dealer do them?
A. Yes, if you are a qualified mechanic and follow the procedures specified in the Owner’s
and Service Manual. We do recommend, however, that items requiring
special tools or equipment be done by a Yamaha ATV dealer.
CHANGE OF ADDRESS
The federal government requires each manufacturer of a motor vehicle to
maintain
a
complete, up-to-date list of all first purchasers against the
possibility of a safety-related defect and recall. This list is compiled from
the purchase registrations sent to Yamaha Motor Corporation, U.S.A. by the
selling dealer at the time of your purchase.
Q. Will the warranty be void or cancelled if I do not operate or maintain my new ATV
exactly as specified in the Owner’s Manual?
A. No. The warranty on a new ATV cannot be “voided” or “cancelled.” However,
if a particular failure is caused by operation or maintenance other than as described
in the Owner’s Manual, that failure may not be covered under warranty.
If you should move after you have purchased your new ATV, please advise
us of your new address by sending
a
postcard listing your ATV model
name, V.I.N. (frame number), dealer number (or dealer’s name) as it is
shown on your warranty card, your name and new mailing address. Mail to:
Q. What responsibility does my dealer have under this warranty?
A. Each Yamaha ATV dealer is expected to:
YAMAHA MOTOR CORPORATION, U.S.A.
P.O. Box 6555
1. Completely set up every new machine before sale.
2. Explain the operation, maintenance, and warranty requirements to your satis-
faction at the time of sale, and upon your request at any later date.
3. Each Yamaha ATV dealer is held responsible for his setup, service and war-
ranty repair work.

Attention: Warranty Department

This will ensure that Yamaha Motor Corporation, U.S.A. has an up-to-date
registration record in accordance with federal law.
Q. Is the warranty transferable to second owners?
A. Yes. The remainder of the existing warranty can be transferred upon request. The
unit has to be inspected and re-registered by an authorized Yamaha ATV dealer
for the policy to remain effective.
