AN ATV IS NOT A TOY AND CAN BE HAZARDOUS TO OPERATE.
An ATV handles differently from other vehicles, including motorcycles and cars. A collision or rollover can occur quickly, even during routine
maneuvers such as turning and riding on hills or
over obstacles, if you fail to take proper precautions.
SEVERE INJURY OR DEATH can result if you do
not follow these instructions:

courses nearest you.
Always follow the age recommendation:
●
Take a Training Course.
Beginners
– A child under 16 years old should never operate an ATV with engine size greater than 90 cc.
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.
Never carry a passenger on an ATV.
●
Always avoid operating an ATV on any paved
●
surfaces, including sidewalks, driveways, parking lots and streets.
Never operate an ATV on any public street, road
●
or highway, even a dirt or gravel one.
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.
Never consume alcohol or drugs before or while
●
operating this ATV.
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.
1
●
Never attempt wheelies, jumps, or other stunts.
●
Always inspect your ATV each time you use it to
2
make sure it is in safe operating condition. Always follow the inspection and maintenance
3
procedures and schedules described in this
manual.
4
●
Always keep both hands on the handlebars and
both feet on the footboards of the ATV during
5
operation.
●
Always go slowly and be extra careful when op-
6
erating on unfamiliar terrain. Always be alert to
changing terrain conditions when operating the
7
ATV.
●
Never operate on excessively rough, slippery or
8
loose terrain until you have learned and prac-
9
ticed the skills necessary to control the ATV on
such terrain. Always be especially cautious on
these kinds of terrain.
●
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.
●
Never operate the ATV on hills too steep for the
ATV or for your abilities. Practice on smaller hills
before attempting larger hills.
●
Always follow proper procedures for climbing
hills as described in this manual. Check the terrain 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.
●
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 vehicle to lean sharply to one side. Go straight
down the hill where possible.
●
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 technique described in this manual on level ground.
Avoid crossing the side of a steep hill if possible.
●
Always use proper procedures if you stall or roll
backwards when climbing a hill. To avoid stall-
1-2
Page 11
ing, use the proper gear and 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 uphill. Turn the ATV around and remount, following
the procedure described in this manual.
●
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 follow
proper procedures when operating over obstacles as described in this manual.
●
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 reduce the chance of skidding or sliding out of control.
●
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.
●
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.
●
Always use the size and type of tires specified in
this manual.
●
Always maintain proper tire pressure as described in this manual.
●
Never modify an ATV through improper installation or use of accessories.
●
Never exceed the stated load capacity for an
ATV. Cargo should be properly distributed and
securely attached. Reduce speed and follow instructions in this manual for carrying cargo or
pulling a trailer. Allow greater distance for braking.

Throttle lever
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 springloaded, the ATV will decelerate, and the engine will
return to an idle any time the hand is removed from
the 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 lever is released.

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

rings, as well as to the exhaust system.
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.

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

EBU20920
Accessories
Accessories can affect the handling and control of
your ATV. Keep the following in mind when consid-
6-7
Page 57
ering 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
limits your ability to move around on the seat, or
one that limits your view.
●
Use extra caution when riding an ATV with accessories. The ATV may handle differently than
it does without accessories.
EBU20930
Loading
As originally equipped, this ATV is not designed 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 as the stability and handling of an ATV
can be changed. When adding accessories, keep
the following points in mind:
●
Never exceed the weight limits shown. An overloaded ATV can be unstable.
MAXIMUM LOADING LIMIT
ATV loading limit (total weight of rider, cargo,
accessories, and tongue):
100.0 kg (220 lb)
●
If you are carrying cargo and towing a trailer, include the tongue weight in the maximum ATV
load limit.
●
Load cargo on the carriers as close to the center
of the ATV as possible. Put cargo at the rear of
the front carrier, at the front of the rear carrier,
and center it.
●
Tie down cargo securely to the carriers. Make
sure cargo in the trailer cannot move around. A
shifting load can cause an accident.

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
the shift pedal. Remember that the engine and exhaust pipe will be hot when riding and afterwards;

With the engine idling, pull the clutch lever to disengage the clutch and shift into 1st gear, and then
2
release the parking brake. Open the throttle gradually, and at the same time, release the clutch le-
3
ver 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
5
release the clutch. Use this same procedure as
you move into the higher gears. Be sure to coordi-
6
nate the use of the throttle and shift pedal properly.
If the throttle is applied too abruptly or if the throttle
7
is not released during shifting, or if the shift pedal
is not released before applying the throttle, the
8
front wheels may lift off the ground, resulting in a
9
loss of directional control. Avoid higher speeds until you are thoroughly familiar with the operation of
10
your ATV.
EWB01240

WARNING
POTENTIAL HAZARD
Opening the throttle abruptly or releasing the
clutch lever too quickly.
WHAT CAN HAPPEN
The ATV could wheelie. This would increase
the chance of an accident, including overturn.
HOW TO AVOID THE HAZARD
Open the throttle gradually. Release the
clutch lever gradually.
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.
7-16
Page 75
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 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 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.

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 outside of the turn to avoid tipping over.
Remember: Avoid higher speeds until you are
thoroughly familiar with the operation of your ATV.

cles. If an incorrect technique is used, your ATV
may continue to go straight. If the ATV doesn’t
11
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.
Once you have learned this technique, you should
CLIMBING UPHILL
Use proper riding techniques to avoid ATV overturns on hills. Be sure that you can maneuver your
ATV well on flat ground before attempting 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 surfaces, or obstacles that might
cause you to lose control.
EWB01090
WARNING
POTENTIAL HAZARD
Operating on excessively steep hills.
7-18
Page 77
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
to overturn.
HOW TO AVOID THE HAZARD
Always follow proper procedures for climbing hills as described in this Owner’s Manual.
Always check the terrain 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. 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 your ATV has stalled or stopped and you believe
you can continue up the hill, restart carefully to
make sure you do not lift the front wheels which
could cause you to lose control. If you are unable
to continue up the hill, dismount the ATV on the uphill side. Physically turn the ATV around and then
descend the hill.
If you start to roll backwards, DO NOT apply the
rear brake to stop or try to put the ATV in gear. The
ATV could easily tip over backwards. Instead, apply the front brake gradually, or dismount the ATV
immediately on the uphill side.
EWB01251
WARNING
POTENTIAL HAZARD
Stalling, rolling backwards or improperly dismounting while climbing a hill.
WHAT CAN HAPPEN
Could result in the ATV overturning.
HOW TO AVOID THE HAZARD
Use the proper gear and maintain a steady
speed when climbing a hill.
If you lose all forward speed:
●
Keep weight uphill.
●
Apply the brakes.
●
Lock the parking brake after you are
stopped.
If you begin rolling backwards:
●
Keep weight uphill.
●
Never apply the rear brake while rolling

RIDING DOWNHILL
When riding your ATV downhill, shift your weight
9
as far to the rear and uphill side of the ATV as possible. Move back on the seat and sit with your arms
10
straight. Choose a low gear which will allow the engine compression to do most of the braking for
11
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
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.

SLIDING AND SKIDDING
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, 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.

WARNING
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.
WHAT TO DO IF...
This section is designed to be a reference guide
only. Be sure to read each section on riding techniques completely.
WHAT TO DO...
●
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
weight on the footboard to the outside of the
turn. Position your weight over the front wheels
for better control. (See page 7-17.)
●
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 page 7-17.)
●
If your ATV starts to slide sideways:
7-28
Page 87
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 7-27.)
●
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 – the ATV may tip over on
top of you. Dismount the ATV on the uphill side.
(See page 7-18.)
●
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 7-18.)
●
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.)

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
8-7
Page 95
plug should be removed and checked in accordance with the periodic maintenance and lubrication chart. In addition, the condition of the spark
plug can reveal the condition of the engine.
To remove the spark plug
1. Remove the spark plug cap.

2. Remove the spark plug as shown, with the
spark plug wrench included in the owner’s tool
kit.
1. Spark plug wrench
To check the spark plug
1. Check that the porcelain insulator around the
center electrode of the spark plug is a medium-to-light tan (the ideal color when the ATV
is ridden normally).
NOTE:
If the spark plug shows a distinctly different color,
the engine could be operating improperly. Do not
attempt to diagnose such problems yourself. Instead, have a Yamaha dealer check the ATV.
2. Check the spark plug for electrode erosion
and excessive carbon or other deposits, and

ness gauge and, if necessary, adjust the gap
to specification.
Spark plug gap:
0.7–0.8 mm (0.028–0.031 in)
1. Spark plug gap
and its mating surface, and then wipe off any
grime from the spark plug threads.
3. Install the spark plug with the spark plug
wrench, and then tighten it to the specified
torque.
Tightening torque:
Spark plug:
12.5 Nm (1.25 m·kgf, 9.1 ft·lbf)
NOTE:
If a torque wrench is not available when installing
a spark plug, a good estimate of the correct torque
is 1/4–1/2 turn past finger tight. However, the spark
plug should be tightened to the specified torque as
soon as possible.
4. Install the spark plug cap.

Engine oil and oil filter element
The engine oil level should be checked before
each ride. In addition, the oil must be changed and
the oil filter element replaced at the intervals specified in the periodic maintenance and lubrication
chart.
2. Clean the surface of the spark plug gasket
8-9
Page 97
To check the engine oil level
1. Place the ATV on a level surface.
2. Start the engine, warm it up until the engine oil
has reached a normal temperature of 60 °C
(141 °F), let it continue to idle for ten seconds
or more, and then turn the engine off.
NOTE:
To achieve the proper engine oil temperature for
an accurate oil level reading, the engine must have
first completely cooled down, and then warmed up
again for several minutes to normal operating temperature.
3. Remove the engine oil tank filler cap, wipe the
dipstick off with a clean rag.
4. Insert the dipstick in the filler hole (without
screwing it in), and then remove it again to
check the oil level.
