SAFETY INFORMATIONEAU41467

Be a Responsible OwnerAs the vehicle’s owner, you are respon-sible for the safe and proper operationof your motorcycle.Motorcycles are single-track vehicles.Their safe use and operation are de-pendent upon the use of proper ridingtechniques as well as the expertise ofthe operator. Every operator shouldknow the following requirements beforeriding this motorcycle.He or she should:

� Obtain thorough instructions froma competent source on all aspectsof motorcycle operation.

� Observe the warnings and mainte-nance requirements in this Own-er’s Manual.

� Obtain qualified training in safeand proper riding techniques.

� Obtain professional technical ser-vice as indicated in this Owner’sManual and/or when made neces-sary by mechanical conditions.

Safe RidingPerform the pre-operation checks eachtime you use the vehicle to make sure itis in safe operating condition. Failure toinspect or maintain the vehicle properlyincreases the possibility of an accidentor equipment damage. See page 5-1for a list of pre-operation checks.

� This motorcycle is designed for off-road use only, therefore, it is illegalto operate it on public streets,roads, or highways, even a dirt orgravel one. Off-road use on publiclands may be illegal. Please checklocal regulations before riding.

� This motorcycle is designed to car-ry the operator only. No passen-gers.

� The failure of motorists to detectand recognize motorcycles in traf-fic is the predominating cause ofautomobile/motorcycle accidents.Many accidents have been causedby an automobile driver who didnot see the motorcycle. Making

yourself conspicuous appears tobe very effective in reducing thechance of this type of accident.Therefore:• Wear a brightly colored jacket.• Use extra caution when you are

approaching and passingthrough intersections, since in-tersections are the most likelyplaces for motorcycle accidentsto occur.

• Ride where other motorists cansee you. Avoid riding in anothermotorist’s blind spot.

� Many accidents involve inexperi-enced operators.• Make sure that you are qualified

and that you only lend your mo-torcycle to other qualified opera-tors.

• Know your skills and limits.Staying within your limits mayhelp you to avoid an accident.

• We recommend that you prac-tice riding your motorcycle untilyou have become thoroughly fa-miliar with the motorcycle and allof its controls.


SAFETY INFORMATION

� Many accidents have been causedby error of the motorcycle opera-tor. A typical error made by the op-erator is veering wide on a turndue to excessive speed or under-cornering (insufficient lean anglefor the speed). Never travel fasterthan warranted by conditions.

� Ride cautiously in unfamiliar ar-eas. You may encounter hiddenobstacles that could cause an ac-cident.

� The posture of the operator is im-portant for proper control. The op-erator should keep both hands onthe handlebar and both feet on theoperator footrests during operationto maintain control of the motorcy-cle.

� Never ride under the influence ofalcohol or other drugs.

� Be sure the transmission is in neu-tral before starting the engine.

Protective ApparelThe majority of fatalities from motorcy-cle accidents are the result of head in-juries. The use of a safety helmet is thesingle most critical factor in the preven-tion or reduction of head injuries.

� Always wear an approved helmet.� Wear a face shield or goggles.

Wind in your unprotected eyescould contribute to an impairmentof vision that could delay seeing ahazard.

� The use of a jacket, heavy boots,trousers, gloves, etc., is effective inpreventing or reducing abrasionsor lacerations.

� Never wear loose-fitting clothes,otherwise they could catch on thecontrol levers, footrests, or wheelsand cause injury or an accident.

� Always wear protective clothingthat covers your legs, ankles, andfeet. The engine or exhaust sys-tem become very hot during or af-ter operation and can cause burns.

Avoid Carbon Monoxide PoisoningAll engine exhaust contains carbonmonoxide, a deadly gas. Breathing car-bon monoxide can cause headaches,dizziness, drowsiness, nausea, confu-sion, and eventually death.Carbon Monoxide is a colorless, odor-less, tasteless gas which may bepresent even if you do not see or smellany engine exhaust. Deadly levels ofcarbon monoxide can collect rapidlyand you can quickly be overcome andunable to save yourself. Also, deadlylevels of carbon monoxide can lingerfor hours or days in enclosed or poorlyventilated areas. If you experience anysymptoms of carbon monoxide poison-ing, leave the area immediately, getfresh air, and SEEK MEDICAL TREAT-MENT.

� Do not run engine indoors. Even ifyou try to ventilate engine exhaustwith fans or open windows anddoors, carbon monoxide can rap-idly reach dangerous levels.

� Do not run engine in poorly venti-lated or partially enclosed areassuch as barns, garages, or car-ports.

� Do not run engine outdoors whereengine exhaust can be drawn intoa building through openings suchas windows and doors.

Genuine Yamaha AccessoriesChoosing accessories for your vehicleis an important decision. GenuineYamaha accessories, which are avail-able only from a Yamaha dealer, havebeen designed, tested, and approvedby Yamaha for use on your vehicle.Many companies with no connection toYamaha manufacture parts and acces-sories or offer other modifications forYamaha vehicles. Yamaha is not in aposition to test the products that theseaftermarket companies produce.Therefore, Yamaha can neither en-dorse nor recommend the use of ac-cessories not sold by Yamaha ormodifications not specifically recom-mended by Yamaha, even if sold andinstalled by a Yamaha dealer.

Aftermarket Parts, Accessories, andModificationsWhile you may find aftermarket prod-ucts similar in design and quality togenuine Yamaha accessories, recog-nize that some aftermarket accessoriesor modifications are not suitable be-cause of potential safety hazards to youor others. Installing aftermarket prod-ucts or having other modifications per-formed to your vehicle that change anyof the vehicle’s design or operationcharacteristics can put you and othersat greater risk of serious injury or death.You are responsible for injuries relatedto changes in the vehicle.Keep the following guidelines in mind,as well as those provided under “Load-ing” when mounting accessories.

� Never install accessories thatwould impair the performance ofyour motorcycle. Carefully inspectthe accessory before using it tomake sure that it does not in anyway reduce ground clearance or

cornering clearance, limit suspen-sion travel, steering travel or con-trol operation.• Accessories fitted to the handle-

bar or the front fork area cancreate instability due to improperweight distribution. If accesso-ries are added to the handlebaror front fork area, they must beas lightweight as possible andshould be kept to a minimum.

• Bulky or large accessories mayseriously affect the stability ofthe motorcycle. Wind may at-tempt to lift the motorcycle, orthe motorcycle may become un-stable in cross winds.

• Certain accessories can dis-place the operator from his orher normal riding position. Thisimproper position limits the free-dom of movement of the opera-tor and may limit control ability,therefore, such accessories arenot recommended.

� Use caution when adding electri-cal accessories. If electrical acces-sories exceed the capacity of themotorcycle’s electrical system, an

electric failure could result, whichcould cause a dangerous loss oflights or engine power.

Aftermarket Tires and RimsThe tires and rims that came with yourmotorcycle were designed to match theperformance capabilities and to providethe best combination of handling, brak-ing, and comfort. Other tires, rims, siz-es, and combinations may not beappropriate. Refer to page 7-14 for tirespecifications and more information onreplacing your tires.

Transporting the MotorcycleBe sure to observe following instruc-tions before transporting the motorcy-cle in another vehicle.

� Remove all loose items from themotorcycle.

� Check that the fuel cock (ifequipped) is in the “OFF” positionand that there are no fuel leaks.

� Point the front wheel straightahead on the trailer or in the truckbed, and choke it in a rail to pre-vent movement.

� Shift the transmission in gear (formodels with a manual transmis-sion).

� Secure the motorcycle with tie-downs or suitable straps that areattached to solid parts of the mo-torcycle, such as the frame or up-per front fork triple clamp (and not,for example, to rubber-mountedhandlebars or turn signals, or partsthat could break). Choose the lo-cation for the straps carefully sothe straps will not rub againstpainted surfaces during transport.

� The suspension should be com-pressed somewhat by the tie-downs, if possible, so that the mo-torcycle will not bounce excessive-ly during transport.

Engine break-in There is never a more important periodin the life of your engine than the first 20hours of riding. For this reason, youshould read the following material care-fully.Since the engine is brand new, do notput an excessive load on it for the first20 hours of operation. The variousparts in the engine wear and polishthemselves to the correct operatingclearances. During this period, pro-longed full-throttle operation or anycondition that might result in engineoverheating must be avoided. Howev-er, momentary full-throttle operationunder load (i.e., two to three secondsmaximum) does not harm the engine.Each full-throttle acceleration shouldbe followed with a substantial rest peri-od for the engine. To allow the engineto cool down from the temporary build-up of heat, cruise at a lower enginespeed.

0–10 hours� Avoid prolonged operation above

1/2 throttle.� After every hour of operation, stop

the engine, and then let it cool forfive to ten minutes.

� Vary the engine speed from time totime. Do not operate the engine atone set throttle position.

10–20 hours� Avoid prolonged operation above

3/4 throttle.� Rev the engine freely through the

gears, but do not use full throttle atany time.

After break-inAvoid prolonged full-throttle operation.Vary the engine speed occasionally.

Checking the spark plug The spark plug is an important enginecomponent, which should be checkedperiodically, preferably by a Yamahadealer. Since heat and deposits willcause any spark plug to slowly erode, itshould be removed and checked in ac-cordance with the periodic mainte-nance and lubrication chart. In addition,the condition of the spark plug can re-veal the condition of the engine.The porcelain insulator around the cen-ter electrode of the spark plug shouldbe a medium-to-light tan (the ideal colorwhen the vehicle is ridden normally). Ifthe spark plug shows a distinctly differ-ent color, the engine could be operatingimproperly. Do not attempt to diagnosesuch problems yourself. Instead, havea Yamaha dealer check the vehicle.If the spark plug shows signs of elec-trode erosion and excessive carbon orother deposits, it should be replaced.

Before installing a spark plug, the sparkplug gap should be measured with awire thickness gauge and, if necessary,adjusted to specification.

Clean the surface of the spark pluggasket and its mating surface, and thenwipe off any grime from the spark plugthreads.

TIPIf a torque wrench is not available wheninstalling a spark plug, a good estimateof the correct torque is 1/4–1/2 turnpast finger tight. However, the sparkplug should be tightened to the speci-fied torque as soon as possible.

Checking the brake fluid level Before riding, check that the brake fluidis above the minimum level mark.Check the brake fluid level with the topof the reservoir level. Replenish thebrake fluid if necessary.

WARNINGEWA15990

Improper maintenance can result inloss of braking ability. Observethese precautions:

� Insufficient brake fluid may al-low air to enter the brake sys-tem, reducing brakingperformance.

� Clean the filler cap before re-moving. Use only DOT 4 brakefluid from a sealed container.

� Use only the specified brake flu-id; otherwise, the rubber sealsmay deteriorate, causing leak-age.

� Refill with the same type ofbrake fluid. Adding a brake fluidother than DOT 4 may result in aharmful chemical reaction.

� Be careful that water does notenter the brake fluid reservoirwhen refilling. Water will signifi-cantly lower the boiling point ofthe fluid and may result in vaporlock.

NOTICEECA17640

Brake fluid may damage painted sur-faces or plastic parts. Always cleanup spilled fluid immediately.

As the brake pads wear, it is normal forthe brake fluid level to gradually godown. A low brake fluid level may indi-cate worn brake pads and/or brake sys-tem leakage; therefore, be sure tocheck the brake pads for wear and thebrake system for leakage. If the brakefluid level goes down suddenly, have aYamaha dealer check the cause beforefurther riding.

EAU41357

Care While the open design of a motorcyclereveals the attractiveness of the tech-nology, it also makes it more vulnera-ble. Rust and corrosion can developeven if high-quality components areused. A rusty exhaust pipe may go un-noticed on a car, however, it detractsfrom the overall appearance of a motor-cycle. Frequent and proper care doesnot only comply with the terms of thewarranty, but it will also keep your mo-torcycle looking good, extend its lifeand optimize its performance.

Before cleaning1. Cover the muffler outlet with a

plastic bag after the engine hascooled down.

2. Make sure that all caps and coversas well as all electrical couplersand connectors, including thespark plug cap, are tightly in-stalled.

3. Remove extremely stubborn dirt,like oil burnt onto the crankcase,with a degreasing agent and abrush, but never apply such prod-

ucts onto seals, gaskets, sprock-ets, the drive chain and wheelaxles. Always rinse the dirt and de-greaser off with water.

Cleaning

NOTICEECA17690

� Avoid using strong acidic wheelcleaners, especially on spokedwheels. If such products areused on hard-to-remove dirt, donot leave the cleaner on the af-fected area any longer than in-structed. Also, thoroughly rinsethe area off with water, immedi-ately dry it, and then apply a cor-rosion protection spray.

� Improper cleaning can damageplastic parts (such as cowlings,panels, windshields, headlightlenses, meter lenses, etc.) andthe mufflers. Use only a soft,clean cloth or sponge with wa-ter to clean plastic. However, ifthe plastic parts cannot be thor-oughly cleaned with water, di-luted mild detergent with watermay be used. Be sure to rinse

off any detergent residue usingplenty of water, as it is harmfulto plastic parts.

� Do not use any harsh chemicalproducts on plastic parts. Besure to avoid using cloths orsponges which have been incontact with strong or abrasivecleaning products, solvent orthinner, fuel (gasoline), rust re-movers or inhibitors, brake flu-id, antifreeze or electrolyte.

� Do not use high-pressure wash-ers or steam-jet cleaners sincethey cause water seepage anddeterioration in the following ar-eas: seals (of wheel and swing-arm bearings, fork and brakes),electric components (couplers,connectors, instruments,switches and lights), breatherhoses and vents.

Short-termAlways store your motorcycle in a cool,dry place and, if necessary, protect itagainst dust with a porous cover. Besure the engine and the exhaust sys-tem are cool before covering the motor-cycle.

NOTICEECA10810

� Storing the motorcycle in apoorly ventilated room or cover-ing it with a tarp, while it is stillwet, will allow water and humid-ity to seep in and cause rust.

� To prevent corrosion, avoiddamp cellars, stables (becauseof the presence of ammonia)and areas where strong chemi-cals are stored.

Long-termBefore storing your motorcycle for sev-eral months:

1. Follow all the instructions in the“Care” section of this chapter.

2. For motorcycles equipped with afuel cock that has an “OFF” posi-tion: Turn the fuel cock lever to“OFF”.

3. Drain the carburetor float chamberby loosening the drain bolt; this willprevent fuel deposits from buildingup. Pour the drained fuel into thefuel tank.

4. Fill up the fuel tank and add fuelstabilizer (if available) to preventthe fuel tank from rusting and thefuel from deteriorating.

5. Perform the following steps to pro-tect the cylinder, 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 placethe spark plug on the cylinderhead so that the electrodes aregrounded. (This will limit spark-ing during the next step.)

d. Turn the engine over severaltimes with the starter. (This willcoat the cylinder wall with oil.)

WARNING! To prevent dam-age or injury from sparking,make sure to ground thespark plug electrodes whileturning the engine over.[EWA10951]

e. Remove the spark plug capfrom the spark plug, and theninstall the spark plug and thespark plug cap.

6. Lubricate all control cables and thepivoting points of all levers andpedals as well as of the side-stand/centerstand.

7. Check and, if necessary, correctthe tire air pressure, and then liftthe motorcycle so that both of itswheels are off the ground. Alterna-tively, turn the wheels a little everymonth in order to prevent the tiresfrom becoming degraded in onespot.

8. Cover the muffler outlet with aplastic bag to prevent moisturefrom entering it.

YAMAHA EXTENDED SERVICE (Y.E.S.) Keep your Yamaha protected even after your warranty expires with genuine Yamaha Extended Service (Y.E.S.).

Y.E.S. is designed and administered by Yamaha Motor Corporation to provide maximum owner satisfaction. You get uninterrupted factory-backed coverage for extra peace of mind.

Y.E.S. is flexible. You choose the plan that’s right foryou: 12 months, 24 months, 36 months or, on certain models, even 48 months beyond your warranty period.

Y.E.S. is designed and administered by the same Yamaha people who handle your warranty – and itshows in the comprehensive coverage benefits. There are no mileage limitations. Coverage isn’t limited to “moving parts” or the “drive train” like many other plans. And Y.E.S. covers manufacturing defects just like the warranty. See the sample contract at your Yamahadealer to see how comforting uninterrupted factory-backed protection can be.

You don’t have to pay anything for covered repairs. There’s no deductible to pay, and repairs aren’t“pro-rated.” You don’t have any “out-of-pocket” expenses for covered repairs.

In addition, Travel and Recreation Interruption Protection (TRIP) is included at no extra cost. TRIP gives you up to $250 reimbursement per occurrence for any reasonable expenses you incur because your Yamaha needs covered service: replacement vehicle rental, emergency towing, phone calls, even food and lodging when you are away from home. This superb coverage goes into effect when you purchase Y.E.S., so it applies to any warranty repairs as well as covered repairs during your entire Y.E.S. plan period.

Y.E.S. coverage is honored at any authorized Yamaha dealer nationwide.

Y.E.S. coverage is transferable to a new owner if yousell or trade-in. That can make your Yamaha much more valuable!

This excellent Y.E.S. plan coverage is only available to Yamaha owners like you, and only while your Yamaha is still within the Yamaha Limited Warranty period. So visit your authorized Yamaha dealer to get all the facts. He can show you how easy it is to protect your investment with Yamaha Extended Service.

We urge you to act now. You’ll get the excellent benefits of TRIP coverage right away, and you’ll rest easy knowing you’ll have strong factory-backed protection even after your Yamaha Limited Warranty expires.

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