SAFETY INFORMATION

EBU17446

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:

● Read this manual and all labels carefully and fol-

low the operating procedures described.

● Never operate an ATV without proper training or

instruction. Take a Training Course.

Beginners
should receive training from a certified instruc­tor. Contact an authorized ATV dealer or call 1­800-887-2887 to find out about the training
courses nearest you.

● Always follow the age recommendation:

– 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.

● Never attempt wheelies, jumps, or other stunts.

2-1

2

● Always inspect your ATV each time you use it to

make sure it is in safe operating condition. Al­ways follow the inspection and maintenance
procedures and schedules described in this

2

manual.

● Always keep both hands on the handlebars and

both feet on the footboards of the ATV during
operation.

● Always go slowly and be extra careful when op-

erating on unfamiliar terrain. Always be alert to
changing terrain conditions when operating the
ATV.

● Never operate on excessively rough, slippery or

loose terrain until you have learned and prac­ticed 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 stall­ing, use the proper gear and maintain a steady

2-2

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 de-

scribed in this manual.

● Never modify an ATV through improper installa-

tion 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.

WARNING

Avoid Carbon Monoxide Poisoning
All engine exhaust contains carbon monoxide,

2

a deadly gas. Breathing carbon monoxide can
cause headaches, dizziness, drowsiness, nau­sea, confusion, and eventually death.
Carbon Monoxide is a colorless, odorless,
tasteless gas which may be present even if you
do not see or smell any engine exhaust. Deadly
levels of carbon monoxide can collect rapidly
and you can quickly be overcome and unable
to save yourself. Also, deadly levels of carbon
monoxide can linger for hours or days in en­closed or poorly ventilated areas. If you experi­ence any symptoms of carbon monoxide
poisoning, leave the area immediately, get
fresh air, and SEEK MEDICAL TREATMENT.

● Do not run engine indoors. Even if you try to

ventilate engine exhaust with fans or open
windows and doors, carbon monoxide can
rapidly reach dangerous levels.

● Do not run engine in poorly ventilated or par-

tially enclosed areas such as barns, garages,
or carports.

● Do not run engine outdoors where engine

exhaust can be drawn into a building
through openings such as windows and
doors.

EWB02591

WARNING

When transporting the ATV in another vehicle,
be sure it is kept upright and that the fuel cock
is in the “OFF” position. Otherwise, fuel may
leak out of the carburetor or fuel tank.

EWB00150

WARNING

Always ride at a slow speed when the ATV is in
four-wheel-drive differential gear lock, and al­low extra time and distance for maneuvers.
All wheels turn at the same speed when the dif­ferential is locked, so it takes more effort to
turn the ATV. The effort needed to turn increas­es with the riding speed. You may lose control
and have an accident if you cannot make a
sharp enough turn for the speed you are trav­eling.

On-Command four-wheel-drive switch
“2WD”/“4WD”

EWB00163

WARNING

Always stop the ATV before changing from
two-wheel drive to four-wheel drive and vice
versa. The ATV handles differently in two­wheel drive than in four-wheel drive in some

4

circumstances. Changing from two-wheel
drive to four-wheel drive or vice versa while
moving may cause the ATV to unexpectedly
handle differently. This could distract the oper­ator and increase the risk of losing control and
of causing an accident.

This ATV is equipped with a switch to change from
two-wheel drive to four-wheel drive and vice versa.
Select the appropriate drive according to the ter­rain and the conditions.

● “2WD” (two-wheel drive): Power is supplied to

the rear wheels.

● “4WD” (four-wheel drive): Power is supplied to

the rear and front wheels.

To change from two-wheel drive to four-wheel
drive, stop the ATV and push the switch in to the
“4WD” position. The four-wheel-drive indicator
light “” comes on.
To change from four-wheel drive to two-wheel
drive, stop the ATV and push the switch in to the
“2WD” position.

EWB00131

WARNING

Always stop the ATV before changing from
four-wheel drive to four-wheel-drive differen­tial gear lock or vice versa.
The ATV handles differently in four-wheel drive
than in differential gear lock in some circum­stances. Changing from four-wheel drive to dif­ferential gear lock or vice versa while moving
may cause the ATV to handle differently unex­pectedly. This could distract the operator and
increase the risk of losing control and causing
an accident.

EWB00140

WARNING

Always ride at a slow speed when the ATV is in
differential gear lock, and allow extra time and
distance for maneuvers.
All wheels turn at the same speed when the dif­ferential gear is locked, so it takes more effort
to turn the ATV. The effort needed to turn in­creases with the riding speed. You may lose

control and have an accident if you cannot
make a sharp enough turn for the speed you
are traveling.

This ATV is equipped with a switch allowing you to
lock the differential gear when in four-wheel drive.
Select the appropriate switch position according to
the terrain and the conditions.

● “4WD” (four-wheel drive): Power is supplied to

the rear and front wheels.

● “LOCK” (four-wheel drive with the differential

gear locked): Power is supplied to the rear and
front wheels and the differential gear is locked.
Unlike in four-wheel drive, all wheels turn at the
same speed.

To release the differential gear lock, stop the ATV
and push the switch to the “4WD” position.

TIP

● If the differential gear lock is not engaging prop-

erly, turn the handlebar back and forth to help it
engage.

● Riding before the differential gear lock is proper-

ly engaged will cause the vehicle speed to be
limited until engagement is complete.

● When the ATV is in four-wheel-drive differential

gear lock, the maximum traveling speed is limit­ed to 31 km/h (19 mi/h). However, if conditions
require full engine power to be available, push

and hold the override switch to disable the differ­ential gear lock speed limiter. (See page 4-6 for
a detailed explanation of this switch.)

EBU18282

Throttle lever

Once the engine is running, pushing the throttle 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 throttle lever is re­leased.

Engine break-in

TIP

● For ATVs equipped with an odometer or an hour

meter, follow the figures given in km (mi) or the
figures given in hours.

● For ATVs not equipped with an odometer or

hour meter, follow the figures given in hours.

There is never a more important period in the life of
your engine than the first 320 km (200 mi) or 20
hours of riding. For this reason, you should read
the following material carefully.

6-5

Since the engine is brand new, do not put an ex­cessive load on it for the first 320 km (200 mi) or 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.

0–160 km (0–100 mi) or 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.

160–320 km (100–200 mi) or 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.

320 km (200 mi) or 20 hours and beyond

The ATV can now be operated normally.

Accessories and loading

EBU20921

Genuine Yamaha Accessories

Choosing accessories for your ATV is an important
decision. Genuine Yamaha Accessories, which
are available only from a Yamaha dealer, have
been designed, tested, and approved by Yamaha
for use on your ATV. Many companies with no con­nection to Yamaha manufacture parts and acces­sories or offer other modifications for Yamaha
vehicles. Yamaha is not in a position to test the
products that these aftermarket companies pro­duce. Therefore, Yamaha can neither endorse nor
recommend the use of accessories not sold by

6-7

Yamaha or modifications not specifically recom­mended by Yamaha, even if sold and installed by
a Yamaha dealer.

Aftermarket parts, accessories, and modifica­tions

While you may find aftermarket products similar in
design and quality to genuine Yamaha Accesso­ries, recognize that some aftermarket accessories
or modifications are not suitable because of poten­tial safety hazards to you or others. Installing after­market products or having other modifications
performed to your ATV that change any of the ve­hicle’s design or operation characteristics can put
you and others at greater risk of serious injury or
death. You are responsible for injuries related to
changes in the vehicle.
Keep the following in mind when considering an
accessory or operating an ATV which has acces­sories.

● 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 inter-

fere 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 ac-

cessories. The ATV may handle differently than
it does without accessories.

EBU21001

Loading

EWB00820

WARNING

Never exceed the stated load capacity for this

● Do not exceed the maximum tongue weight.

You can measure tongue weight with a bath­room scale. Put the tongue of the loaded trailer
on the scale with the tongue at hitch height. Ad­just the load in the trailer, if necessary, to reduce

the weight on the hitch. 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.

● Make sure the load does not interfere with con-

trols 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
handling of the ATV.

This ATV is mainly for utility use, but may also be
used for recreation. This section, Riding your ATV,
provides general ATV riding instructions for recre­ational riding. The skills and techniques described
in this section, however, are appropriate for all
types of riding. Riding your ATV requires special
skills acquired through practice over a period of
time. Take the time to learn the basic techniques
well before attempting more difficult maneuvers.
Riding your new ATV can be a very enjoyable ac­tivity, providing you with hours of pleasure. But it is
essential to familiarize yourself with the operation
of the ATV to achieve the skill necessary to enjoy
riding safely. Before you begin to ride, be sure you
have read this Owner’s Manual completely and un­derstand the operation of the controls. Pay partic-

ular attention to the safety information on pages
2-1–2-5. Also read all warning and notice labels on
your ATV.

RIDE WITH CARE AND GOOD JUDGMENT

Get training if you are inexperienced.

EWB01381

WARNING

● Do not operate this ATV or allow anyone else

to operate it without proper instruction. The
risk of an accident is greatly increased if the
operator does not know how to operate the
ATV properly in different situations and on
different types of terrain.

● Do not operate this ATV at speeds too fast

for your skills or the conditions, as this in­creases your chances of losing control of
the ATV and an accident. Always go at a
speed that is proper for the terrain, visibility
and operating conditions, and your experi­ence.

Beginning and inexperienced operators should
complete the certified training course offered by
Yamaha. They should then regularly practice the
skills learned in the course and the operating tech-

7

of age.

EWB01390

WARNING

A child under 16 should never operate an ATV
with engine size greater than 90 cc. Use by chil­dren of ATVs that are not recommended for
their age can lead to severe injury or death of
the child.

This ATV is designed to carry the operator and
cargo only – passengers prohibited.

The long seat is to allow the operator to shift posi­tion as needed during operation. It is not for carry­ing passengers. WARNING! Never carry a

passenger. Carrying a passenger on this ATV
greatly reduces your ability to balance and
control this ATV. You could have an accident,
resulting in severe injury or death to you
and/or your passenger.

an accident:

● Approved motorcycle helmet that fits properly

● Eye protection (goggles, helmet face shield, or

protective eyewear)

● Over-the-ankle boots, gloves, long-sleeved shirt

or jacket, and long pants
An approved helmet and other personal protective
equipment can reduce the severity of injuries in an
accident. WARNING! Operating without an ap-

proved motorcycle helmet increases your
chances of a severe head injury or death in the
event of an accident.

[EWB01411]

Wear eye protection when operating your ATV to
reduce the risk of a serious accident or injury. Eye
protection, such as a face shield or goggles, may
reduce the risk of foreign material getting in your
eyes and help prevent loss of vision. WARNING!

Operating without eye protection can result in
an accident and increases your chances of a
severe injury in the event of an accident.

The operator’s performance capability is reduced
by the influence of alcohol or drugs. Consuming al­cohol or drugs could seriously affect your judg­ment, cause you to react more slowly, and affect
your balance and perception. WARNING! Never

consume alcohol or drugs before or while driv­ing this ATV. You increase your chance of an
accident.

[EWB01421]

Pre-operation checks

Always inspect your ATV each time you use it to
make sure the ATV is in safe operating condition.
Perform the pre-operation checks listed on page
5-1. Always follow the inspection and maintenance
procedures and schedules described in the Own­er’s Manual. WARNING! Failure to inspect the

ATV before operating it and to maintain it prop­erly increases the possibility of an accident or
equipment damage.

[EWB01431]

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

7-5

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
4-11.)

Loading and accessories

EWB01462

WARNING

Improper loading or towing can increase the
risk of loss of control, an overturn, or other ac­cident. To reduce the risk of an accident:

● Do not exceed the maximum loading limits

for the vehicle (see “MAXIMUM LOADING

LIMIT” in this section or vehicle labeling).

● Keep weight on racks centered side to side,

and as low as possible. Be sure cargo is se-

cured – a loose load could change handling

unexpectedly.

● Make sure the load does not interfere with

your control or ability to see where you are

going.

● Tie down cargo in the trailer securely. Make

sure cargo in the trailer cannot move around.

A shifting load can cause an accident.

● Reduce speed and allow more room to stop.

A heavier vehicle takes longer to stop.

● Avoid hills and rough terrain. Choose terrain

carefully. Use extreme caution when towing

or carrying a load on inclines.

● Turn gradually and go slowly.

Take extra precautions when driving with a load or
trailer. Follow these instructions and always use

EWB01501

WARNING

● Dry grass or brush or other combustible ma-

terial accumulated around the engine area
could catch fire. Do not operate, idle, or park
the ATV in dry grass or other dry ground cov­er. Keep the engine area free of dry grass,
brush, or other combustible material.

● Someone touching the exhaust system dur-

ing or after operation could be burned. Do
not touch the hot exhaust system. Do not
park the ATV in a place where others might
be likely to touch it.

The muffler and other engine parts become ex­tremely hot during operation and remain hot after
the engine has stopped. To reduce the risk of fire
during operation or after leaving the ATV, do not let
brush, grass and other materials collect under the
vehicle, near the muffler or exhaust pipe, or next to
other hot parts. Check under the vehicle after op­erating in areas where combustible materials may
have collected. Do not idle or park the vehicle in
long dry grass or other dry ground cover.

BE CAREFUL WHERE YOU RIDE

This ATV is designed for off-road use only.

WARNING! Paved surfaces may seriously af­fect handling and control of the ATV, and may
cause the ATV to go out of control. Always
avoid paved surfaces, including sidewalks,
driveways, parking lots and streets.

[EWB01511]

Do not ride on any public road, street, or highway.
Riding on public roads can result in collisions with
other vehicles. In many states it is illegal to operate
ATVs on public streets, roads and highways.

7-9

WARNING! Never operate this ATV on any pub­lic street, road or highway, even a dirt or gravel
one. You could collide with another vehicle.

[EWB01031]

Know the terrain where you ride. Ride cautiously in
unfamiliar areas. Stay alert for holes, rocks, or
roots in the terrain, and other hidden hazards
which may cause the ATV to upset. WARNING!

The ATV could go out of control if you do not
have enough time to react to hidden rocks,
bumps, or holes. Go slowly and be extra care­ful when operating on unfamiliar terrain. Al­ways be alert to changing terrain conditions
when operating the ATV.

[EWB01531]

Do not operate on rough, slippery, or loose terrain
until you have learned and practiced the skills nec­essary to control the ATV on such terrain. Always
be especially cautious on these kinds of terrain.

WARNING! Failure to use extra care when op­erating on excessively rough, slippery, or
loose terrain could cause loss of traction or
ATV control, which could result in an accident,
including an overturn.

When riding in an area where you might not easily
be seen, such as desert terrain, mount a caution
flag on the ATV. DO NOT use the flag pole bracket
as a trailer hitch. WARNING! You could collide

with another vehicle if operating in off-road ar­eas where you cannot easily be seen. Mount a
caution flag on the ATV to make you more vis­ible. Watch carefully for other vehicles.

Do not ride in areas posted “no trespassing”.
Do not ride on private property without getting per­mission.

[EWB01061]

7-11

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.
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. With the engine idling, lift the shift
pedal to the 1st gear position and then release the
parking brake. Apply the throttle slowly and
smoothly. The centrifugal clutch will engage and
you will start to accelerate. Once the ATV has at­tained adequate speed, release the throttle and lift
the shift pedal to the 2nd gear position. Release
the shift pedal and apply the throttle smoothly.

WARNING! 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 ap­plying the throttle, the front wheels may lift off
the ground, resulting in a loss of directional
control.

[EWB02631] NOTICE: Do not shift gears

without releasing the throttle. Damage to the
engine or drive train may occur.

[ECB01071]

Use this same procedure as you move into the
higher gears. Be sure to coordinate the use of the
throttle and shift pedal properly.
Avoid higher speeds until you are thoroughly famil­iar with the operation of your ATV.
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.

TURNING YOUR ATV

EWB01771

WARNING

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. ATV could go
out of control, causing a collision or overturn.

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,

7-12

7

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.
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.

7

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.
Once you have learned this technique, you should
be able to perform it at higher speeds or in tighter
curves.

7-13

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 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.

CLIMBING UPHILL

EWB01591

WARNING

Climbing hills improperly can cause overturns
or loss of control. Use proper riding tech­niques described in this Owner’s Manual.

● Never operate the ATV on hills too steep for

the ATV or for your abilities. The ATV can
overturn more easily on extremely steep hills
than on level surfaces or small hills.

● 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.

● Never attempt to turn the ATV around on any

hill until you have mastered the turning tech­nique 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 pos-

sible. When crossing the side of a hill, shift
your weight to the uphill side of the ATV.

7

7-14

Do not attempt to climb hills until you have mas­tered basic maneuvers on flat ground. Always
check the terrain carefully before attempting any
hill. In all cases avoid inclines with slippery or loose
surfaces, or obstacles that might cause you to lose
control.
To climb a hill, you need traction, momentum, and
steady throttle. For more traction and control for
climbing steeper and/or rougher slopes, select
“4WD” or 4WD-LOCK (“DIFF. LOCK”). Travel fast
enough to maintain momentum, but not so fast that
you cannot react to changes in the terrain as you
climb.

7

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. Whenev­er possible, ride straight up hills.
Slow down when you reach the crest of the hill if
you cannot see clearly what is on the other side –
there could be another person, an obstacle, or a
sharp drop-off. Use common sense and remember
that some hills are too steep for you to climb or de­scend.

7-15

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.
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 either
brake abruptly. If you are in “2WD”, apply only the
front brake. When fully stopped, apply the rear
brake as well, and then lock the parking brake. If
you are in “4WD” or 4WD-LOCK, because all
wheels are interconnected by the drive train, ap­plying either brake will brake all wheels, therefore,
avoid sudden application of either the front or rear
brake as the wheels on the uphill side could come
off the ground. The ATV could easily tip over back­wards. Apply both the front and rear brakes gradu­ally. When fully stopped, lock the parking brake
and dismount the ATV immediately on the 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. WARNING!

Stalling, rolling backwards or improperly dis­mounting while climbing a hill could result in
ATV overturning. If you cannot control the
ATV, dismount immediately on the uphill side.

[EWB01802]

7-16

RIDING DOWNHILL

EWB01621

WARNING

Going down a hill improperly could cause
overturns or loss of control. Always follow
proper procedures for going down hills as de­scribed in this Owner’s Manual.

● Always check the terrain carefully before

you start down any hill.

● Never operate the ATV on hills too steep for

the ATV or for your abilities. The ATV can
overturn more easily on extremely steep hills
than on level surfaces or small hills.

● Shift your weight backward and to the up

7

side of the hill.

● Never go down a hill at high speed.

● Avoid going down a hill at an angle that

would cause the ATV to lean sharply to one
side. Go straight down the hill where possi­ble.

● Improper braking can cause the wheels on

the uphill side to come off the ground or
cause loss of traction. Apply brakes gradual­ly. If in “2WD”, apply only the rear brake.

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. Engine compression will do most of the
braking for you. For maximum engine compres­sion braking effect, change to “4WD” before begin-
ning to descend the hill.
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.
When this ATV is in “4WD”, all wheels (front and
rear) are interconnected by the drive train. This
means that applying either the front brake or the
rear brake will brake all wheels. When descending
hills, using either brake lever or the brake pedal will
brake the wheels on the downhill side. Avoid sud­den application of either the front or rear brake be­cause the wheels on the uphill side could come off
the ground. Apply both the front and rear brakes
gradually.
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.

7-17

CROSSING A SLOPE

EWB01632

WARNING

Improperly crossing hills or turning on hills
could cause loss of control or cause the ATV to
overturn.

● Always follow proper procedures as de-

scribed in the Owner’s Manual.

● Avoid hills with excessively slippery or loose

surfaces.

● Avoid crossing the side of a steep hill.

● 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 as described in the Owner’s Manual on
level ground. Be very careful when turning
on any hill.

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
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.

CROSSING THROUGH SHALLOW WATER

EWB01641

WARNING

Operating this vehicle through deep or fast­flowing water can lead to loss of control or an
overturn. To reduce your risk of drowning or
other injuries, use care when crossing through
water. Never operate this ATV water deeper
than the depth specified in your Owner’s Man­ual, as tires may float, increasing the risk of an
overturn.

The ATV can be used to cross slow moving, shal­low water of up to a maximum of 35 cm (14 in) in
depth. Before entering the water, choose your path
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 care­fully.

Test your brakes after leaving the water. If neces­sary, apply them several times to let friction dry out
the linings. Do not continue to ride your ATV with­out verifying that you have regained proper braking

7-19

ability. WARNING! Wet brakes may have re-

duced stopping ability, which could cause loss
of control.

[EWB02621]

1. Air filter case check hose

After riding your ATV in water, be sure to drain the
trapped water by removing the check hose at the
bottom of the air filter case. NOTICE: Undrained

water can cause damage or improper opera­tion.

[ECB00841]

Wash the ATV in fresh water if it has been operat­ed in salt water or muddy conditions.

RIDING OVER ROUGH TERRAIN

EWB01651

WARNING

Riding improperly over obstacles could cause
loss of control or a collision. Before operating
in a new area, check for obstacles. Never at­tempt to ride over large obstacles, such as
large rocks or fallen trees. When you go over
obstacles, always follow proper procedures as
described in the Owner’s Manual.

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 ac-

7-20

7

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 re­sult.

SLIDING AND SKIDDING

EWB01662

WARNING

Skidding or sliding improperly may cause you
to lose control of this ATV. You may also re­gain traction unexpectedly, which may cause
the ATV to overturn.

● Learn to safely control skidding or sliding by

practicing at low speeds and on level,

7

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.

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.

7-21

With practice, over a period of time, skill at con­trolled sliding can be developed. The terrain
should be chosen carefully before attempting 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.

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 7-12.)

● 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 7-12.)

● 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 7-21.)

● 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 7-14.)

7

7-22

● 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

7

ride your ATV until you have regained adequate
braking ability. (See page 7-19.)

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 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.

1. Spark plug cap

2. Remove the spark plug as shown, with the
spark plug wrench included in the owner’s tool
kit.

8-9

1. Spark plug wrench

To check the spark plug

1. Check that the porcelain insulator around the

8

center electrode of the spark plug is a medi­um-to-light tan (the ideal color when the ATV
is ridden normally).

TIP

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
replace it if necessary.

Specified spark plug:

NGK/DR8EA

3. Measure the spark plug gap with a wire thick­ness gauge and, if necessary, adjust the gap
to specification.

1. Spark plug gap

Spark plug gap:

0.6–0.7 mm (0.024–0.028 in)

8-10

To install the spark plug

1. Clean the surface of the spark plug gasket
and its mating surface, and then wipe off any
grime from the spark plug threads.

2. Install the spark plug with the spark plug
wrench, and then tighten it to the specified
torque.

EBU2327E

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 cleaned at the intervals speci­fied in the periodic maintenance and lubrication
chart.

Tightening torque:

Spark plug:

18 Nm (1.8 m·kgf, 13 ft·lbf)

TIP

If a torque wrench is not available when installing
the 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.

3. Install the spark plug cap.

To check the engine oil level

1. Place the ATV on a level surface.

2. Check the engine oil level on a cold engine.

TIP

If the engine was started before checking the oil
level, be sure to warm up the engine sufficiently,
and then wait at least ten minutes until the oil set­tles for an accurate reading.

3. Remove the engine oil filler cap, and then
wipe the engine oil dipstick off with a clean
rag.
