INTRODUCTION

EBU17260

Congratulations on your purchase of the Yamaha YFM80RX. This ATV represents the result of many yearsof Yamaha experience in the production of fine sporting, touring, and pacesetting racing machines. With thepurchase of this Yamaha, you can now appreciate the high degree of craftsmanship and reliability that havemade Yamaha a leader in these fields.This manual will provide you with a good basic understanding of the features and operation of this ATV.

This manual includes important safety information. It provides information about special tech-niques and skills necessary to ride the ATV.

It also includes basic maintenance and inspection proce-dures. If you have any questions regarding the operation or maintenance of your ATV, please consult aYamaha dealer.

AN IMPORTANT SAFETY MESSAGE:

�

READ THIS MANUAL COMPLETELY BEFORE OPERATING YOUR ATV. MAKE SURE YOU UNDER-STAND ALL INSTRUCTIONS.

�

PAY CLOSE ATTENTION TO THE WARNING AND CAUTION LABELS ON THE ATV.

�

THIS ATV, AND ANY OTHER ATV OVER 70 cc, SHOULD NOT BE OPERATED BY A CHILD UNDER12 YEARS OF AGE.

AN IMPORTANT NOTE TO PARENTS:

This ATV is not a toy. Before you let your child ride this ATV, you should understand the instructions andwarnings in this Owner’s Manual. Then be sure your child understands and will follow them. Children differin skills, physical abilities and judgment. Some children may not be able to operate an ATV safely. Parentsshould supervise their child’s use of the ATV at all times. Parents should permit continued use only if theydetermine that the child has the ability to operate the ATV safely.

Your ATV was delivered with an adjustable speed limiter and also with an air intake restrictor plate. Yamaharecommends that all beginners start off with the speed limiter screw turned in and the air intake restrictorplate installed to limit the amount of speed available while they learn. The limiter screw may be graduallyturned out to increase maximum speed as the beginner becomes more familiar with operating the ATV. Par-ents should decide when to adjust the ATV for more power as their youngster’s riding skills improve. Oncethe ATV rider can operate with skill at the top speed permitted by adjusting the speed limiter alone, the airintake restrictor plate can be removed. Since removal of this plate will result in a significant increase in pow-er, turn the speed limiter completely back in again; adjust it out in stages as you did before.If your child is a beginner or is inexperienced, he or she should take a training course.

Before starting the engine, check the throttle to besure it is operating smoothly. Make sure it returnsto the idle position as soon as the lever is released.

WARNING

EWB00250

Malfunction of the throttle could make it diffi-cult to speed up or slow down when you needto. This could cause an accident. Check the op-eration of the throttle lever before you start theengine. If the throttle does not work smoothly,check for the cause. Correct the problem be-

fore riding the ATV or consult a Yamaha dealer.

EBU18341

Speed limiter and air intake restrictor plate

Your ATV was delivered with an adjustable speedlimiter and an air intake restrictor plate. Yamaharecommends that all beginning riders start off withthe speed limiter adjusting screw fully turned in andthe air intake restrictor plate installed to limit theamount of speed available while they learn.The speed limiter keeps the throttle from fullyopening, even when the throttle lever is pushed tothe maximum. The adjusting screw may be gradu-ally turned out as the beginner becomes more fa-miliar with operating the ATV. Parents shoulddecide when to adjust the ATV for more power astheir youngster’s riding skills improve. Once theATV rider can operate with skill at the top speedpermitted by adjusting the speed limiter alone, theair intake restrictor plate can be removed. Since re-moval of this plate will result in a significant in-crease in power, turn the adjusting screwcompletely back in again; adjust it out in stages asdone previously.1. Loosen the locknut.2. To increase the maximum engine power avail-

able and the maximum speed of the ATV, turn

Accessories

Accessories can affect the handling and control ofyour ATV. Keep the following in mind when consid-ering an accessory or operating an ATV which hasaccessories.

�

Choose only accessories designed for yourATV. Your Yamaha dealer has a variety of gen-uine Yamaha accessories. Other accessoriesmay also be available on the market. However,it is not possible for Yamaha to test all non-

Yamaha accessories, nor control over their qual-ity or suitability. Choose a genuine Yamaha ac-cessory, or one that is equivalent in design andquality.

�

Accessories should be rigidly and securelymounted. An accessory which can shift positionor come off while you are riding could affect yourability to control the ATV.

�

Do not mount an accessory where it could inter-fere with your ability to control the ATV. Exam-ples include (but are not limited to) a heavy orbulky object attached to the handlebars whichcould make steering difficult, an accessory thatlimits your ability to move around on the seat, orone that limits your view.

�

Use extra caution when riding an ATV with ac-cessories. The ATV may handle differently thanit does without accessories.

EBU20940

Loading

As originally equipped, this ATV is not designed tocarry cargo or tow a trailer. If you choose to add ac-cessories so that you can carry cargo or tow a trail-er, you must use common sense and goodjudgment as the stability and handling of an ATVcan be changed. When adding accessories, keep

the following points in mind:

�

Never exceed the weight limits shown. An over-loaded ATV can be unstable.

�

If you are carrying cargo and towing a trailer, in-clude the tongue weight in the maximum ATVload limit.

�

Load cargo on the carriers as close to the centerof the ATV as possible. Put cargo at the rear ofthe front carrier, at the front of the rear carrier,and center it.

�

Tie down cargo securely to the carriers. Makesure cargo in the trailer cannot move around. Ashifting 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 youshould go. Although conditions vary, it is goodpractice not to exceed 2nd gear whenever youare carrying heavier loads or when towing a trail-er.

�

Allow more braking distance. A heavier ATVtakes longer to stop.

�

Avoid making sharp turns unless at very slowspeeds.

�

Avoid hills and rough terrain. Choose terraincarefully. Added weight affects the stability andhandling of the ATV.

WARNING

EWB00820

Never exceed the stated load capacity for thisATV. Overloading this ATV or carrying or tow-ing cargo improperly could cause changes inATV handling which could lead to an accident.Cargo should be properly distributed and se-curely attached.

ATV, which can result in an accident.

Speed limiter

For riders less experienced with this model, thethrottle lever housing is equipped with a speed lim-iter. The speed limiter keeps the throttle from fullyopening, even when the throttle lever is pushed tothe maximum. Turning in the adjusting screw limitsthe maximum engine power available and de-creases the maximum speed of the ATV. Turningin the adjusting screw decreases top speed, andturning it out increases top speed. (See page 4-3.)

This model also has an air intake restrictor plate tolimit the amount of engine power available.Yamaha recommends that all beginning ridersstart off with the speed limiter turned in and the airintake restrictor plate installed to limit the amountof speed available while they learn. The limiter maybe gradually adjusted to increase maximum speedas the beginner becomes more familiar with oper-ating the ATV. Parents should decide when to ad-just the ATV for more power as their youngster’sriding skills improve. Once the ATV rider can oper-ate with skill at the top speed permitted by adjust-ing the speed limiter alone, the air intake restrictorplate can be removed. Since removal of this platewill result in a significant increase in power, turnthe speed limiter back in again; adjust it out in stag-es as you did before.Adjusting for maximum throttle lever movementwithout removing the air intake restrictor plate willcause the engine to run roughly at higher speeds.For air intake restrictor plate removal instructions,see page 8-17.

BE CAREFUL WHERE YOU RIDE

This ATV is designed for use on unpaved surfacesonly. Riding on paved surfaces can cause loss ofcontrol.

WARNING

EWB01510

Always avoid paved surfaces, including side-walks, driveways, parking lots and streets.ATVs are designed for use on unpaved surfac-es only. Paved surfaces may seriously affecthandling and control of the ATV, and may

cause the ATV to go out of control.

While riding on unpaved public streets or roadsmay be legal in your area, such operation can in-crease the risk of collision with other vehicles.Watch carefully for other vehicles. Make sure youknow your country’s laws and regulations beforeyou ride on unpaved public streets or roads. Do notride on any paved public street, road or motorway.

Select a large, flat, unpaved area to become famil-iar with your ATV. Make sure that this area is freeof obstacles and other riders. You should practicecontrol of the throttle, brakes, shifting procedures,and turning techniques in this area before tryingmore difficult terrain. Always avoid riding on pavedsurfaces: the ATV is designed for use on unpavedsurfaces only, and handling maneuvers are moredifficult to perform on pavement.Set the parking brake and follow the instruction onpage 6-1 to start the engine. Once it has warmedup you are ready to begin riding your ATV. As youget on the ATV, be sure not to accidentally movethe shift pedal. Remember that the engine and ex-haust pipe will be hot when riding and afterwards;do not allow skin or clothing to come in contact with

these components.With the engine idling, lift the shift pedal to the 1stgear position and then release the parking brake.Apply the throttle slowly and smoothly. The centrif-ugal clutch will engage and you will start to accel-erate. Once the ATV has attained adequatespeed, release the throttle and lift the shift pedal tothe 2nd gear position. Release the shift pedal andapply the throttle smoothly. Use this same proce-dure as you move into the higher gears. Be sure tocoordinate the use of the throttle and shift pedalproperly. If the throttle is applied too abruptly or ifthe throttle is not released during shifting, or if theshift pedal is not released before applying thethrottle, the front wheels may lift off the ground, re-sulting in a loss of directional control. Avoid higherspeeds until you are thoroughly familiar with theoperation of your ATV.

CAUTION:

ECB00230

Do not shift gears without releasing the throt-tle. Damage to the engine or drive train may oc-

cur.

When slowing down or stopping, release the throt-tle and apply the brakes smoothly and evenly. Asyou slow down, shift to a lower gear. Be sure that

7-13

the engine has sufficiently slowed before engaginga lower gear. Improper use of the brakes or shiftingcan cause the tires to lose traction, reducing con-trol and increasing the possibility of an accident.

WARNING

EWB01560

Make sure the engine has sufficiently slowedbefore shifting to a lower gear. Engaging a low-er gear when the engine speed is too high

could cause the wheels to stop rotating.

TURNING YOUR ATV

To achieve maximum traction on unpaved surfac-es, the two rear wheels are mounted solidly on oneaxle and turn together at the same speed. There-fore, unless the wheel on the inside of the turn is al-lowed to slip or lose some traction, the ATV willresist turning. A special turning technique must beused to allow the ATV to make turns quickly andeasily. It is essential that this skill be learned first atlow speed.

WARNING

EWB01570

Always follow proper procedures for turningas described in this Owner’s Manual. Practiceturning 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 toturn the handlebars in the desired direction. As youdo so, put your weight on the footboard to the out-side of the turn (opposite your desired direction)and lean your upper body into the turn. Use thethrottle to maintain an even speed through theturn. This maneuver will let the wheel on the insideof the turn slip slightly, allowing the ATV to makethe turn properly.

This procedure should be practiced at slow speedmany times in a large unpaved area with no obsta-cles. If an incorrect technique is used, your ATVmay continue to go straight. If the ATV doesn’tturn, come to a stop and then practice the proce-dure again. If the riding surface is slippery or loose,it may help to position more of your weight over thefront wheels by moving forward on the seat.Once you have learned this technique, you shouldbe able to perform it at higher speeds or in tighter

curves.Improper riding procedures such as abrupt throttlechanges, excessive braking, incorrect body move-ments, or too much speed for the sharpness of theturn may cause the ATV to tip. If the ATV begins totip over to the outside while negotiating a turn, leanmore to the inside. It may also be necessary togradually let off on the throttle and steer to the out-side of the turn to avoid tipping over.Remember: Avoid higher speeds until you arethoroughly familiar with the operation of your ATV.

CLIMBING UPHILL

Use proper riding techniques to avoid ATV over-turns on hills. Be sure that you can maneuver yourATV well on flat ground before attempting any in-cline and then practice riding first on gentle slopes.Try more difficult climbs only after you have devel-oped your skill. In all cases avoid inclines with slip-pery or loose surfaces, or obstacles that mightcause you to lose control.

WARNING

EWB01580

Never operate the ATV on hills too steep for theATV or for your abilities. The ATV can overturnmore easily on extremely steep hills than onlevel surfaces or small hills. Practice on small-

er hills before attempting large hills.

It is important when climbing a hill to make surethat your weight is transferred forward on the ATV.This can be accomplished by leaning forward and,on steeper inclines, standing on the footboardsand leaning forward over the handlebars.

WARNING

EWB01590

�

Always follow proper procedures for climb-ing hills as described in this Owner’s Manu-al.

�

Always check the terrain carefully beforeyou start up any hill.

�

Never climb hills with excessively slippery orloose surfaces.

�

Shift your weight forward.

�

Never open the throttle suddenly or makesudden gear changes. The ATV could flipover backwards.

�

Never go over the top of any hill at highspeed. An obstacle, a sharp drop, or anothervehicle or person could be on the other side

of the hill.

If you are climbing a hill and you find that you havenot properly judged your ability to make it to thetop, you should turn the ATV around while you stillhave forward motion (provided you have the roomto do so) and go down the hill.

WARNING

EWB01600

Never attempt to turn the ATV around on anyhill until you have mastered the turning tech-nique as described in the Owner’s Manual onlevel ground. Be very careful when turning onany hill. Avoid crossing the side of a steep hill

Always follow proper procedures as de-scribed in the Owner’s Manual.

�

Avoid hills with excessively slippery or loosesurfaces.

�

Shift your weight to the uphill side of the

ATV.

If your ATV has stalled or stopped and you believeyou can continue up the hill, restart carefully tomake sure you do not lift the front wheels whichcould cause you to lose control. If you are unable

to continue up the hill, dismount the ATV on the up-hill side. Physically turn the ATV around and thendescend the hill.If you start to roll backwards, DO NOT apply therear brake to stop or try to put the ATV in gear. TheATV could easily tip over backwards. Instead, ap-ply the front brake gradually, or dismount the ATVimmediately on the uphill side.

WARNING

EWB01711

Use the proper gear and maintain a steadyspeed when climbing a hill.If you lose all forward speed:

�

Keep weight uphill.

�

Apply the brakes.

�

Lock the parking brake after you arestopped.

If you begin rolling backwards:

�

Keep weight uphill.

�

Never apply the rear brake while rollingbackwards. Apply the front brake.

RIDING DOWNHILL

When riding your ATV downhill, shift your weightas far to the rear and uphill side of the ATV as pos-sible. Move back on the seat and sit with your armsstraight. Choose a low gear which will allow the en-gine compression to do most of the braking foryou. Improper braking may cause a loss of trac-tion.Use caution while descending a hill with loose orslippery surfaces. Braking ability and traction maybe adversely affected by these surfaces. Improper

braking may also cause a loss of traction.Whenever possible, ride your ATV straight down-hill. Avoid sharp angles which could allow the ATVto tip or roll over. Carefully choose your path andride no faster than you will be able to react to ob-stacles which may appear.

WARNING

EWB01620

Always follow proper procedures for goingdown hills as described in this Owner’s Manu-al.Note: a special technique is required whenbraking as you go down a hill.

�

Always check the terrain carefully beforeyou start down any hill.

�

Shift your weight backward.

�

Never go down a hill at high speed.

�

Avoid going down a hill at an angle thatwould cause the ATV to lean sharply to oneside. Go straight down the hill where possi-

ble.

CROSSING A SLOPE

Traversing a sloping surface on your ATV requiresyou to properly position your weight to maintainproper balance. Be sure that you have learned thebasic riding skills on flat ground before attemptingto cross a sloping surface. Avoid slopes with slip-pery surfaces or rough terrain that may upset yourbalance.As you travel across a slope, lean your body in theuphill direction. It may be necessary to correct thesteering when riding on loose surfaces by pointingthe front wheels slightly uphill. When riding on

slopes, be sure not to make sharp turns either upor down hill.If your ATV does begin to tip over, gradually steerin the downhill direction if there are no obstacles inyour path. As you regain proper balance, graduallysteer again in the direction you wish to travel.

CROSSING THROUGH SHALLOW WATER

The ATV can be used to cross slow moving, shal-low water of up to a maximum of 20 cm (8 in) indepth. Before entering the water, choose your pathcarefully. Enter where there is no sharp drop off,and avoid rocks or other obstacles which may beslippery or upset the ATV. Drive slowly and care-fully.

WARNING

EWB01640

Never operate this ATV in fast flowing water orin water deeper than that specified in your

Owner’s Manual. Remember that wet brakesmay have reduced stopping ability. Test yourbrakes after leaving water. If necessary, applythem several times to let friction dry out the lin-ings. If the ATV is operated through deep orfast flowing water, the tires may float, causingloss of traction and loss of control, which

could lead to an accident.

Test your brakes after leaving the water. Do notcontinue to ride your ATV without verifying that youhave regained proper braking ability.

SLIDING AND SKIDDING

Care should be used when riding on loose or slip-pery surfaces since the ATV may slide. If unex-pected and uncorrected, sliding could lead to anaccident.To reduce the tendency for the front wheels to slidein loose or slippery conditions, positioning yourweight over the front wheels will sometimes help.

If the rear wheels of your ATV start to slide side-ways, control can usually be regained (if there isroom to do so) by steering in the direction of theslide. Applying the brakes or accelerating is notrecommended until you have corrected the slide.

With practice, over a period of time, skill at con-trolled sliding can be developed. The terrainshould be chosen carefully before attempting suchmaneuvers, since both stability and control are re-duced. Bear in mind that sliding maneuvers shouldalways be avoided on extremely slippery surfacessuch as ice, since all control may be lost.

WHAT TO DO IF...

This section is designed to be a reference guideonly. Be sure to read each section on riding tech-niques completely.

WHAT TO DO...

�

If your ATV doesn’t turn when you want it to:Bring the ATV to a stop and practice the turningmaneuvers again. Be sure you are putting yourweight on the footboard to the outside of theturn. Position your weight over the front wheelsfor better control. (See page 7-13.)

�

If your ATV begins to tip while turning:Lean more into the turn to regain balance. If nec-essary, gradually let off the throttle and/or steerto the outside of the turn. (See page 7-13.)

�

If your ATV starts to slide sideways:Steer in the direction of the slide if you have theroom. Applying the brakes or accelerating is notrecommended until you have corrected theslide. (See page 7-21.)

�

If your ATV can’t make it up a hill you are tryingto climb:Turn the ATV around if you still have forwardspeed. If not, stop, dismount on the uphill side ofthe ATV and physically turn the ATV around. Ifthe ATV starts to slip backwards, DO NOT USETHE REAR BRAKE – the ATV may tip over ontop of you. Instead, apply the front brake or dis-mount the ATV on the uphill side. (Seepage 7-14.)

�

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 maintainproper balance. If the ATV starts to tip, steerdown the hill (if there are no obstacles in yourway) to regain balance. If you discover that theATV is going to tip over, dismount on the uphillside. (See page 7-14.)

Checking the spark plug

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

To check the spark plug

1. Check that the porcelain insulator around thecenter electrode of the spark plug is a medi-um-to-light tan (the ideal color when the ATVis ridden normally).

NOTE:

If the spark plug shows a distinctly different color,the engine could be operating improperly. Do notattempt to diagnose such problems yourself. In-

stead, have a Yamaha dealer check the ATV.

Troubleshooting

Although Yamaha ATVs receive a thorough in-spection before shipment from the factory, troublemay occur during operation. Any problem in the fu-el, compression, or ignition systems, for example,can cause poor starting and loss of power.The following troubleshooting chart represents aquick and easy procedure for checking these vitalsystems yourself. However, should your ATV re-quire any repair, take it to a Yamaha dealer, whoseskilled technicians have the necessary tools, expe-rience, and know-how to service the ATV properly.Use only genuine Yamaha replacement parts. Im-itation parts may look like Yamaha parts, but theyare often inferior, have a shorter service life andcan lead to expensive repair bills.

Cleaning

Frequent, thorough cleaning of your ATV will notonly enhance its appearance but will improve itsgeneral performance and extend the useful life ofmany components.1. Before cleaning the ATV:

a. Block off the end of the exhaust pipe toprevent water entry. A plastic bag andstrong rubber band may be used.

b. Make sure the spark plug and all filler capsare properly installed.

2. If the engine case is excessively greasy, applydegreaser with a paint brush. Do not apply de-greaser to the wheel axles.

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

CAUTION:

ECB00710

Excessive water pressure may cause waterseepage and deterioration of wheel bearings,brakes, transmission seals and electrical de-vices. Many expensive repair bills have result-ed from improper high-pressure detergent

applications such as those available in coin-

operated car washers.

4. Once most of the dirt has been hosed off,wash all surfaces with warm water and mild,detergent-type soap. An old toothbrush or bot-tle brush is handy for hard-to-reach places.

5. Rinse the ATV off immediately with clean wa-ter and dry all surfaces with a chamois, cleantowel or soft absorbing cloth.

6. Clean the seat with a vinyl upholstery cleanerto keep the cover pliable and glossy.

7. Automotive type wax may be applied to allpainted and chrome plated surfaces. Avoidcombination cleaner-waxes. Many containabrasives which may mar the paint or protec-tive finish. When finished cleaning, start theengine and let it idle for several minutes.

WARNING

EWB02310

Wet brakes may have reduced stopping ability,increasing the chance of an accident. Test thebrakes after washing. Apply the brakes severaltimes at slow speeds to let friction dry out the

Storage

Short-term

Always store your ATV in a cool, dry place and, ifnecessary, protect it against dust with a porouscover.

CAUTION:

ECB00720

�

Storing the ATV in a poorly ventilated roomor covering it with a tarp while it is still wet,will allow water and humidity to seep in andcause rust.

�

To prevent corrosion, avoid damp cellars,stables (because of the presence of ammo-nia) and areas where strong chemicals are

stored.

Long-term

Before storing your ATV for several months:1. Follow all the instructions in the “Cleaning”

section of this chapter.2. Turn the fuel cock lever to “OFF”.3. Drain the carburetor float chamber by loosen-

ing the drain bolt; this will prevent fuel depositsfrom building up. Pour the drained fuel into thefuel tank.

4. Fill up the fuel tank and add fuel stabilizer (ifavailable) to prevent the fuel from deteriorat-ing.

5. Perform the following steps to protect the cyl-inder, piston rings, etc. from corrosion.a. Remove the spark plug cap and spark

plug.b. Pour a teaspoonful of engine oil into the

spark plug bore.c. Install the spark plug cap onto the spark

plug, and then place the spark plug on thecylinder head so that the electrodes aregrounded. (This will limit sparking duringthe next step.)

d. Turn the engine over several times withthe starter. (This will coat the cylinder wallwith oil.)

e. Remove the spark plug cap from the sparkplug, and then install the spark plug and

Specified amount:7.5 ml of stabilizer to each liter of fuel (or 1 oz of stabilizer to each gallon of fuel)

the spark plug cap.6. Lubricate all control cables and the pivoting

points of all levers and pedals.7. Check and, if necessary, correct the tire air

pressure, and then block up the ATV so thatall of its wheels are off the ground. Alternative-ly, turn the wheels a little every month in orderto prevent the tires from becoming degradedin one spot.

8. Cover the muffler outlet with a plastic bag toprevent moisture from entering it.

9. Remove the battery and fully charge it. Storeit in a cool, dry place and charge it once amonth. Do not store the battery in an exces-sively cold or warm place [less than 0 °C (30°F) or more than 30 °C (90 °F)]. For more in-formation on storing the battery, see page8-29.

NOTE:

Make any necessary repairs before storing the

ATV.
