AN IMPORTANT NOTE TO PARENTS: This ATV is not a toy... Before you let your child ride this ATV, you should understand the instructions and warnings in this Owners Manual... Then be sure your child understands and will follow them... Children differ in skills, physical abilities and judgment... Some children may not be able to operate an ATV safely... Parents should supervise their childs use of the ATV at all times... Parents should permit continued use only if they determine that the child has the ability to operate the ATV safely... Your ATV was delivered with an adjustable speed limiter... Yamaha recommends that all beginners start off to limit the amount of speed available while they learn... The adjusting screw may be gradually turned out as the beginner becomes more familiar with operating the ATV... Parents should decide when to adjust the ATV for more power as their youngsters riding skills improve... Once the ATV rider can operate with skill at the top speed permitted by adjusting the vehicle speed limiter alone, the engine speed limiter plate can be removed... Since removal of this limiter will result in a significant increase in power, turn the vehicle speed limiter adjusting screw completely back in again; adjust it out in stages as done previously... If your child is a beginner or is inexperienced, he or she should take a training course... See the previous page for information about the free training available to purchasers of new ATVs...

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... SEVERE INJURY OR DEATH can result if you do not follow these instructions: Read this manual and all labels carefully and fol-

Page 14

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...

Page 15

Always use proper procedures if you stall or roll backwards when climbing a hill... To avoid stall- 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 up- hill... Turn the ATV around and remount, following the procedure described in this manual...

Page 16

3... If your injuries are light, when safe to do so, move your vehicle off the trail to avoid colli- sions with oncoming riders... Check for injuries and apply first aid as necessary... If you can physically operate your vehicle, inspect your vehicle... If the vehicle is in safe operating con- dition and you can safely operate it, restart it and ride gently back to camp or other known location where you can receive medical at-

Page 17

Aftermarket Parts, Accessories, and Modifica- tions While you may find aftermarket products similar in design and quality to genuine Yamaha accesso- ries, recognize that some aftermarket accessories or modifications are not suitable because of po- tential safety hazards to you or others... Installing aftermarket products or having other modifica- tions performed to your vehicle that change any of the vehicles design or operation characteristics can put you and others at greater risk of serious injury or death... You are responsible for injuries re-

Avoid Carbon Monoxide Poisoning All engine exhaust contains carbon monoxide, a deadly gas... Breathing carbon monoxide can cause headaches, dizziness, drowsiness, nau- sea, 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 en- closed or poorly ventilated areas... If you experi- ence 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

Speed limiter Your ATV was delivered with two speed limiter de- vices... A vehicle speed limiter adjusting screw and a removable engine speed limiter plate... Yamaha recommends that all beginning riders start off with the vehicle speed limiter adjusting screw fully turned in and the engine speed limiter plate in- stalled to limit the amount of speed available while they learn... The vehicle speed limiter keeps the throttle from fully opening, even when the throttle lever is pushed to the maximum... The adjusting screw may be gradually turned out as the beginner becomes more familiar with operating the ATV... Parents should decide when to adjust the ATV for more power as their youngsters riding skills improve... Once the ATV rider can operate with skill at the top speed permitted by adjusting the vehicle speed limiter alone, the engine speed limiter plate can be removed... Since removal of this plate will result in a significant increase in power, turn the vehicle

Front brake lever The front brake lever is located on the right han- dlebar... To apply the front brake, pull the brake le- ver toward the handlebar grip...

Page 27

Parking brake Use the parking brake before starting the engine or after parking the ATV, especially on a slope... Ap- ply the rear brake lever and push down the lock plate to apply the parking brake... Squeeze the rear brake lever to release the parking brake...

Page 28

Always be sure you have released the park- ing brake before you begin to ride... The brake could overheat if you ride the ATV without re- leasing the parking brake... You could lose braking performance which could cause an accident... You could also wear out the brakes prematurely...

Page 29

3... Move the kickstarter lever down lightly with your foot until the gears engage, and then push it down smoothly but forcefully...

Page 30

2... Do not overfill the fuel tank... When refueling, be sure to insert the pump nozzle into the fuel tank filler hole... Stop filling when the fuel reaches the bottom of the filler tube... Because fuel expands when it heats up, heat from the engine or the sun can cause fuel to spill out of the fuel tank...

Page 31

Gasoline is poisonous and can cause injury or death... Handle gasoline with care... Never siphon gasoline by mouth... If you should swallow some gasoline or inhale a lot of gasoline vapor, or get some gasoline in your eyes, see your doctor immediately... If gasoline spills on your skin, wash with soap and water... If gasoline spills on your clothing, change your clothes...

Page 32

Fuel cock The fuel cock supplies fuel from the tank to the carburetor while also filtering it... The fuel cock lever positions are explained as fol- lows and shown in the illustrations...

Page 33

This indicates reserve... With the fuel cock lever in this position, the fuel reserve is made available... Turn the fuel cock lever to this position if you run out of fuel while riding... When this occurs, refuel as soon as possible and be sure to turn the fuel cock lever back to ON!

Page 34

Always adjust the shock absorber assemblies on the left and right side to the same setting... Uneven adjustment can cause poor handling and loss of stability, which could lead to an ac- cident...

Page 35

Adjust the spring preload as follows... Turn the spring preload adjusting ring in direction (a) to increase the spring preload and thereby harden the suspension, and in direction (b) to de- crease the spring preload and thereby soften the suspension... Align the appropriate notch in the adjusting ring with the position indicator on the shock absorber...

Indicates a hazardous situation which, if not avoided, could result in death or serious injury...

Page 38

Failure to inspect or maintain the vehicle properly increases the possibility of an accident or equip- ment damage... Do not operate the vehicle if you find any problem... If a problem cannot be corrected by the procedures provided in this manual, have the vehicle inspected by a Yamaha dealer...

Page 39

Wheels and tires Check wheel condition, and replace if damaged... Check tire condition and tread depth... Replace if necessary... Check air pressure... Correct if necessary...

Page 40

Brake operation Test the brakes at slow speed after starting out to make sure they are working properly... If the brakes do not provide proper braking performance, check the brake shoes for wear... (See page 8-21... )

Page 41

Tire pressure Use the low-pressure tire gauge to check and ad- just tire pressures when the tires are cold... Tire pressures must be equal on both sides... WARNING! Operation of this vehicle with im- proper tire pressure may cause severe injury or death from loss of control or rollover... Tire pressure below the minimum specified could also cause the tire to dislodge from the rim un- der severe riding conditions... [EWB02542] Set tire pressures to the following specifications:

Page 42

After extensive tests, only the tires listed below have been approved for this model by Yamaha Motor Co... , Ltd...

Page 43

Aftermarket tires and rims The tires and rims that came with your ATV were designed to match the performance capabilities and to provide the best combination of handling, braking, and comfort... Other tires, rims, sizes, and combinations may not be appropriate...

Page 44

5... Use the starter (choke) in reference to the fig- ure: Position (1): Cold engine start with ambient temperature below 5 C (40 F)... Position (2): Cold engine start with ambient temperature between 0 C (30 F) and 30 C (90 F)... Position (3): Cold engine start with ambient temperature above 25 C (80 F)...

Page 45

7... If the engine is started with the starter (choke) in position (1), the starter (choke) should be returned to position (2) to warm up the en- gine... If the engine is started with the starter (choke) in position (2), keep the starter (choke) in this position to warm up the engine...

Page 46

Improper operation in reverse could make you hit an obstacle or even a person behind you, resulting in serious injury... When you shift into reverse, make sure there are no people or ob- stacles behind you... When it is safe to proceed, go slowly...

Page 47

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... Since the engine is brand new, do not put an ex- cessive 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 clear- ances... During this period, prolonged full-throttle operation or any condition that might result in en- gine overheating must be avoided...

Page 48

Avoid parking on hills or other inclines... Parking on a hill or other incline could cause the ATV to roll out of control, increasing the chance of an accident... If you must park on an incline, place the ATV transversely across the incline, shift the drive select lever to the forward position, stop the engine, apply the parking brake, and then block the front and rear wheels with rocks or other objects...

Page 49

Genuine Yamaha Accessories Choosing accessories for your ATV is an impor- tant 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 compa- nies produce... Therefore, Yamaha can neither en- dorse nor recommend the use of accessories not sold by Yamaha or modifications not specifically recommended by Yamaha, even if sold and in- stalled by a Yamaha dealer...

Page 50

aftermarket products or having other modifica- tions performed to your ATV that change any of the vehicles design or operation characteristics can put you and others at greater risk of serious injury or death... You are responsible for injuries re- lated to changes in the vehicle... Keep the following in mind when considering an accessory or operating an ATV which has acces- sories... Accessories should be rigidly and securely

GETTING TO KNOW YOUR ATV This ATV is intended for recreational use by young operators under adult supervision... This section, Riding your ATV, provides general riding instruc- tions which 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 at- tempting more difficult maneuvers... Riding your new ATV can be a very enjoyable ac- tivity, providing you with hours of pleasure... But it is essential to familiarize yourself with the opera- tion of the ATV to achieve the skill necessary to enjoy riding safely... Before you begin to ride, be sure you have read this manual completely and understand how to operate all of the ATVs con- trols... Pay particular attention to the safety infor- mation on pages 2-1 to 2-7 and all notice and warning labels on the vehicle...

Page 54

Riding your ATV requires skills acquired through practice over a period of time... Become familiar with riding this ATV by riding at slow speeds first, even if you have experience rid- ing other ATVs... Do not attempt to operate it at higher performance levels until you are familiar with this ATVs handling and performance charac- teristics... Take the time to learn the basic tech- niques well before attempting more difficult maneuvers...

Page 55

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... [EWB02612]

Page 56

Pre-operation checks Always inspect your ATV before use to make sure that it is safe operating condition... Perform the pre- operation checks listed on page 5-1... Follow the maintenance schedules and procedures as de- scribed in the Periodic Maintenance and Adjust- ment section of this manual... WARNING! Failure to inspect the ATV before riding it or failure to maintain it properly increases the possibility of an accident and equipment damage... [EWB01433]

Page 57

vehicle speed limiter... 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 decreases the maximum speed of the ATV... Turning in the adjusting screw decreases top speed, and turning it out increases top speed... (See page 4-3... ) This model also has an engine speed limiter plate to limit the amount of engine power available... Yamaha recommends that all beginning riders start off with the engine speed limiter plate in- stalled and the vehicle speed limiter adjusting screw turned in to limit the amount of speed avail- able while they learn... The vehicle speed limiter may be gradually adjusted to increase maximum speed as the beginner becomes more familiar with operating the ATV... Parents should decide when to adjust the ATV for more power as their young- sters riding skills improve... Once the ATV rider can operate with skill at the top speed permitted by adjusting the vehicle speed limiter alone, the en- gine speed limiter plate can be removed... Since re- moval of this plate will result in a significant increase in power, turn the vehicle speed limiter adjusting screw back in again and adjust it out in

Page 58

During operation Always keep your feet on the footboards during operation; otherwise, they may contact the rear wheels... WARNING! Removing even one hand or foot can reduce your ability to control the ATV or could cause you to lose your balance and fall off of the ATV... If you remove a foot from a footboard, your foot or leg may come into con- tact with the rear wheels, which could injure you or cause an accident... [EWB01472]

Page 59

Modifications and accessories Never modify this ATV through improper installa- tion or use of accessories or other modification... All parts and accessories added to this ATV should be genuine Yamaha or equivalent components designed for use on this ATV and should be in- stalled and used according to instructions... If you have questions, consult an authorized ATV dealer... WARNING! Operating this ATV with improper modifications may cause changes in handling which in some situations could lead to an acci- dent... [EWB01492]

Page 60

The muffler and other engine parts become ex- tremely 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 mate- rials may have collected... Do not idle or park the vehicle in long dry grass or other dry ground cov- er...

Page 61

BE CAREFUL WHERE YOU RIDE This ATV is designed for off-road use only... WARNING! Paved surfaces may seriously af- fect 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... [EWB01512]

Page 62

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 care- ful when operating on unfamiliar terrain... Al- ways be alert to changing terrain conditions when operating the ATV... [EWB01532]

Page 63

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, and turning tech- niques in this area before trying more difficult ter- rain... 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... Re- member that the engine and exhaust pipe will be hot when riding and afterwards; do not allow skin or clothing to come in contact with these compo- nents... With the engine idling, release the parking brake... Apply the throttle slowly and smoothly... You will start to accelerate... If the throttle is applied too

Page 64

ing 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 direc- tion) 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...

Page 65

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 throt- tle 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 be- gins to tip over to the outside while negotiating a turn, lean more to the inside... It may also be nec- essary 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...

Page 66

Never attempt to turn the ATV around on any hill until you have mastered the turning tech- nique as described in the Owners Manual on level ground... Be very careful when turning on any hill...

Page 67

on steeper inclines, standing on the footboards and leaning forward over the handlebars... When- ever 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 remem- ber that some hills are too steep for you to climb or descend... 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 the brakes abruptly... Apply only the front brake... When fully stopped, apply the rear brake as well, and then lock the parking brake... The ATV could easily tip over backwards so immediately dismount the

Page 68

ATV on the uphill side or to the left-hand side when the ATV is pointed straight uphill... If possible, get help to turn the ATV around and then remount it when safe and ride downhill carefully as ex- plained in the following section... WARNING! Stall- ing, 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... [EWB01803]

Page 69

When riding your ATV downhill, shift your weight as far to the rear and uphill side of the ATV as pos- sible... Move back on the seat and sit with your arms straight... Engine compression will do most of the braking for you... 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... Gradu- ally apply only the rear brake... Whenever possible, ride your ATV straight down- hill... 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 ob- stacles which may appear...

Page 70

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, grad- ually steer again in the direction you wish to travel...

Page 71

Operating this vehicle through deep or fast- flowing 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 Owners Man- ual, as tires may float, increasing the risk of an overturn...

Page 72

Test your brakes after leaving the water... If neces- sary, 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 ability... WARNING! Wet brakes may have reduced stopping ability, which could cause loss of control... [EWB02622]

Page 73

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...

Page 74

If your ATV cant 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 7-15... )

Page 75

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... )

Page 76

Periodic inspection, adjustment, and lubrication will keep your vehicle in the safest and most effi- cient condition possible... Safety is an obligation of the vehicle owner/operator... The most important points of vehicle inspection, adjustment, and lu- brication are explained on the following pages...

Page 83

TIP Some maintenance items need more frequent service if you are riding in unusually wet, dusty, sandy or muddy areas, or at full-throttle...

Page 84

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 ac- cordance with the periodic maintenance and lubri- cation chart... In addition, the condition of the spark plug can reveal the condition of the engine...

Page 85

TIP If the spark plug shows a distinctly different color, the engine could be operating improperly... Do not attempt to diagnose such problems yourself... In- stead, have a Yamaha dealer check the ATV...

Page 86

TIP If a torque wrench is not available when installing the spark plug, a good estimate of the correct torque is 1/41/2 turn past finger tight... However, the spark plug should be tightened to the speci- fied torque as soon as possible...

Transmission oil The transmission case must be checked for oil leakage before each ride... If any leakage is found, have a Yamaha dealer check and repair the ATV... In addition, the transmission oil must be changed at the intervals specified in the periodic mainte- nance and lubrication chart...

Page 90

Cleaning the air filter element The air filter element should be serviced at the in- tervals specified in the periodic maintenance and lubrication chart... Clean or, if necessary, replace the air filter element more frequently if you are rid- ing in unusually wet or dusty areas...

Page 91

4... Remove the air filter element, and clean it with solvent... WARNING! Always use parts cleaning solvent to clean the air filter ele- ment... Never use low-flash-point solvents or gasoline to clean the air filter element because the engine could catch fire or ex- plode... [EWB03540]
