CAUTION:  
Use only unleaded gasoline. The use of leaded  
gasoline will cause severe damage to internal  
engine parts, such as the valves and piston  
4-8  
rings, as well as to the exhaust system.  
WHAT CAN HAPPEN  
Fuel can spill, which can cause a fire and se-  
vere 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.  
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.

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.  
Do not refuel right after the engine has been  
running and is still very hot.

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.  
With the engine idling, return the starter knob to the  
closed position and shift the drive select lever into  
the forward position. Then release the parking  
brake. Apply the throttle slowly and smoothly. The  
centrifugal clutch will engage and you will start to  
accelerate. If the throttle is applied too abruptly, the  
front wheels may lift off the ground, resulting in a  
loss of directional control. Avoid higher speeds un-  
til you are thoroughly familiar with the operation of  
your ATV.  
When slowing down or stopping, release the throt-  
tle and apply the brakes smoothly and evenly. Im-  
proper use of the brakes can cause the tires to lose  
traction, reducing control and increasing the possi-  
bility of an accident.

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.  
9
10  
11  
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. There-  
fore, unless the wheel on the inside of the turn is al-  
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  
7-16  
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.

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.  
Try more difficult climbs only after you have devel-  
oped your skill. In all cases avoid inclines with slip-  
pery or loose surfaces, or obstacles that might  
cause you to lose control.  
1. Lean towards inside of turn.  
2. Support your weight on the outer footboard.  
7
8
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.

Never attempt to turn the ATV around on any  
hill until you have mastered the turning tech-  
nique as described in the Owner’s Manual on  
level ground. Be very careful when turning  
on any hill. Avoid crossing the side of a steep  
hill if possible.  
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 slip-  
pery surfaces or rough terrain that may upset your  
balance.

carefully. Enter where there is no sharp drop off,  
and avoid rocks or other obstacles which may be  
slippery or upset the ATV. Drive slowly and care-

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.

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

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.

WARNING  
POTENTIAL HAZARD  
Skidding or sliding improperly.  
7-26  
Lean more into the turn to regain balance. If nec-  
essary, gradually let off the throttle and/or steer  
to the outside of the turn. (See page 7-16.)  
G If your ATV starts to slide sideways:  
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 7-25.)  
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 re-  
duce the chance of skidding or sliding out of  
control.

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 – the ATV may tip over on  
top of you. Dismount the ATV on the uphill side.  
(See page 7-17.)  
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 7-17.)

Checking the spark plug  
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.

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.  
6. Dry the chain and lubricate it to prevent it from  
rusting.  
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 protec-  
tive finish. When finished cleaning, start the  
engine and let it idle for several minutes.

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

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:  
1
2
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.

6
Q. May I perform any or all of the recommended maintenance shown in the Owner’s  
Manual instead of having the dealer do them?  
CHANGE OF ADDRESS  
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.  
The federal government requires each manufacturer of a motor vehicle to  
maintain  
a
complete, up-to-date list of all first purchasers against the  
7
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.  
8
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  
9
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:  
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.

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.

YAMAHA EXTENDED SERVICE (Y.E.S.)

Keep your Yamaha protected even after your warranty  
expires with genuine Yamaha Extended Service (Y.E.S.).  
In addition, Travel and Recreation Interruption Protection  
(TRIP) is included at no extra cost. TRIP gives you up to  
$150 reimbursement per occurrence for any reasonable  
expenses you incur because your Yamaha needs  
covered service: replacement vehicle rental, emergency  
towing, phone calls, even food and lodging when you are  
away from home. This superb coverage goes into effect  
when you purchase Y.E.S., so it applies to any warranty  
repairs as well as covered repairs during your entire  
Y.E.S. plan period.  
Y.E.S. is designed and administered by Yamaha Motor  
Corporation to provide maximum owner satisfaction. You  
get uninterrupted factory-backed coverage for extra  
peace of mind.

Y. E. S. is flexible. You choose the plan that’s right for  
you: 12 months, 24 months, or 36 months beyond your  
warranty period.

Y.E.S. coverage is honored at any authorized Yamaha  
dealer nationwide.  
Y.E.S. is designed and administered by the same

Yamaha people who handle your warranty  
–
and it  
Y.E.S. coverage is transferable to a new owner if you  
sell or trade in your ATV. That can make your Yamaha  
much more valuable!  
shows in the comprehensive coverage benefits. There  
are no mileage limitations. Coverage isn’t limited to  
“moving parts” or the “drive train” like many other plans.  
And Y.E.S. covers manufacturing defects just like the  
warranty. See the sample contract at your Yamaha  
dealer to see how comforting uninterrupted factory-  
backed protection can be.

8
This excellent Y.E.S. plan coverage is only available to  
Yamaha owners like you, and only while your Yamaha is still  
within the Yamaha Limited Warranty period. So visit your  
authorized Yamaha dealer to get all the facts. He can show  
you how easy it is to protect your investment with Yamaha  
Extended Service.  
9
You don’t have to pay anything for covered repairs.  
There’s no deductible to pay, and repairs aren’t  
“pro-rated.” You don’t have any “out-of-pocket” expenses  
for covered repairs.  
10  
11  
11-7  
We urge you to act now. You’ll get the excellent benefits of  
TRIP coverage right away, and you’ll rest easy knowing  
you’ll have strong factory-backed protection even after your  
Yamaha Limited Warranty expires. You can also save  
money: Y.E.S. costs less within the first 90 days after you  
buy your Yamaha. See your dealer today!

A special note:  
If visiting your dealer isn’t convenient, contact Yamaha with  
your Primary ID number (your frame number). We’ll be  
happy to help you get the Y.E.S. coverage you need.
