SAFETY INFORMATION EAU10313

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 to car-ry the operator and a passenger.

� 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. Makingyourself 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. In fact, many op-erators who have been involved inaccidents do not even have a cur-rent motorcycle license.• 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 motorcyclewhere there is no traffic until youhave become thoroughly famil-iar with the motorcycle and all ofits controls.

� Many accidents have been causedby error of the motorcycle opera-tor. A typical error made by the op-erator is veering wide on a turn

due to excessive speed or under-cornering (insufficient lean anglefor the speed).• Always obey the speed limit and

never travel faster than warrant-ed by road and traffic conditions.

• Always signal before turning orchanging lanes. Make sure thatother motorists can see you.

� The posture of the operator andpassenger is important for propercontrol.• The operator should keep both

hands on the handlebar andboth feet on the operator foot-rests during operation to main-tain control of the motorcycle.

• The passenger should alwayshold onto the operator, the seatstrap or grab bar, if equipped,with both hands and keep bothfeet on the passenger footrests.Never carry a passenger unlesshe or she can firmly place bothfeet on the passenger footrests.

� Never ride under the influence ofalcohol or other drugs.

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.

� A passenger should also observethe above precautions.

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.

LoadingAdding accessories or cargo to yourmotorcycle can adversely affect stabili-ty and handling if the weight distributionof the motorcycle is changed. To avoidthe possibility of an accident, use ex-treme caution when adding cargo oraccessories to your motorcycle. Useextra care when riding a motorcyclethat has added cargo or accessories.Here, along with the information aboutaccessories below, are some generalguidelines to follow if loading cargo toyour motorcycle:The total weight of the operator, pas-senger, accessories and cargo mustnot exceed the maximum load limit.Operation of an overloaded vehiclecould cause an accident.

When loading within this weight limit,keep the following in mind:

� Cargo and accessory weightshould be kept as low and close tothe motorcycle as possible. Se-curely pack your heaviest items asclose to the center of the vehicle aspossible and make sure to distrib-ute the weight as evenly as possi-ble on both sides of the motorcycleto minimize imbalance or instabili-ty.

� Shifting weights can create a sud-den imbalance. Make sure that ac-cessories and cargo are securelyattached to the motorcycle beforeriding. Check accessory mountsand cargo restraints frequently.• Properly adjust the suspension

for your load, and check the con-dition and pressure of your tires.

• Never attach any large or heavyitems to the handlebar, frontfork, or front fender. Theseitems, including such cargo assleeping bags, duffel bags, ortents, can create unstable han-dling or a slow steering re-sponse.

� This vehicle is not designed topull a trailer or to be attached toa sidecar.

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 or carrycargo that would impair the perfor-mance of your motorcycle. Care-fully inspect the accessory beforeusing it to make sure that it doesnot in any way reduce groundclearance or cornering clearance,limit suspension travel, steeringtravel or control operation, or ob-scure lights or reflectors.• Accessories fitted to the handle-

bar or the front fork area cancreate instability due to improperweight distribution or aerody-namic changes. If accessories

are added to the handlebar orfront fork area, they must be aslightweight as possible andshould be kept to a minimum.

• Bulky or large accessories mayseriously affect the stability ofthe motorcycle due to aerody-namic effects. Wind may at-tempt to lift the motorcycle, orthe motorcycle may become un-stable in cross winds. These ac-cessories may also causeinstability when passing or beingpassed by large vehicles.

• 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, anelectric 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 7-22 for tirespecifications and more information onreplacing your tires.

NOTICEECA11400

Use only unleaded gasoline. The useof leaded gasoline will cause severedamage to internal engine parts,such as the valves and piston rings,as well as to the exhaust system.

Your Yamaha engine has been de-signed to use premium unleaded gaso-line with a pump octane number[(R+M)/2] of 91 or higher, or a research

octane number of 95 or higher. Ifknocking (or pinging) occurs, use agasoline of a different brand. Use of un-leaded fuel will extend spark plug lifeand reduce maintenance costs.GasoholThere are two types of gasohol: gaso-hol containing ethanol and that contain-ing methanol. Gasohol containingethanol can be used if the ethanol con-tent does not exceed 10% (E10). Gas-ohol containing methanol is notrecommended by Yamaha because itcan cause damage to the fuel systemor vehicle performance problems.

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.

NOTICEECA10840

Do not use any tools to remove or in-stall the spark plug cap, otherwisethe ignition coil coupler may getdamaged. The spark plug cap maybe difficult to remove because therubber seal on the end of the cap fitstightly. To remove the spark plugcap, simply twist it back and forthwhile pulling it out; to install it, twistit back and forth while pushing it in.

Engine oil and oil filter ele-ment The engine oil level should be checkedbefore each ride. In addition, the oilmust be changed and the oil filter ele-ment replaced at the intervals specifiedin the periodic maintenance and lubri-cation chart.

To check the engine oil level1. Place the vehicle on a level sur-

face and hold it in an upright posi-tion. A slight tilt to the side canresult in a false reading.

2. Start the engine, warm it up forseveral minutes, and then turn itoff.

3. Wait a few minutes until the oil set-tles, and then check the oil levelthrough the check window locatedat the bottom-right side of thecrankcase.

TIPThe engine oil should be between theminimum and maximum level marks.

4. If the engine oil is below the mini-mum level mark, add sufficient oilof the recommended type to raiseit to the correct level.

To change the engine oil (with orwithout oil filter element replace-ment)

1. Place the vehicle on a level sur-face.

2. Start the engine, warm it up forseveral minutes, and then turn itoff.

3. Place an oil pan under the engineto collect the used oil.

Insufficient brake fluid may allow air toenter the brake system, possibly caus-ing it to become ineffective.

Before riding, check that the brake fluidis above the minimum level mark andreplenish if necessary. A low brake fluidlevel may indicate worn brake padsand/or brake system leakage. If thebrake fluid level is low, be sure to checkthe brake pads for wear and the brakesystem for leakage.Observe these precautions:

� When checking the fluid level,make sure that the top of the brakefluid reservoir is level.

� Use only the recommended qualitybrake fluid, otherwise the rubberseals may deteriorate, causingleakage and poor braking perfor-mance.

� Refill with the same type of brakefluid. Mixing fluids may result in aharmful chemical reaction andlead to poor braking performance.

Matte color caution

NOTICEECA15192

Some models are equipped withmatte colored finished parts. Besure to consult a Yamaha dealer foradvice on what products to use be-fore cleaning the vehicle. Using abrush, harsh chemical products orcleaning compounds when cleaningthese parts will scratch or damagetheir surface. Wax also should notbe applied to any matte colored fin-ished parts.

EAU26004

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

NOTICEECA10772

� 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.

� For motorcycles equipped witha windshield: Do not use strongcleaners or hard sponges asthey will cause dulling orscratching. Some cleaning com-pounds for plastic may leavescratches on the windshield.

Test the product on a small hid-den part of the windshield tomake sure that it does not leaveany marks. If the windshield isscratched, use a quality plasticpolishing compound afterwashing.

After normal useRemove dirt with warm water, a milddetergent, and a soft, clean sponge,and then rinse thoroughly with cleanwater. Use a toothbrush or bottlebrushfor hard-to-reach areas. Stubborn dirtand insects will come off more easily ifthe area is covered with a wet cloth fora few minutes before cleaning.

After riding in the rain, near the sea oron salt-sprayed roadsSince sea salt or salt sprayed on roadsduring winter are extremely corrosive incombination with water, carry out thefollowing steps after each ride in therain, near the sea or on salt-sprayedroads.

TIPSalt sprayed on roads in the winter mayremain well into spring.

1. Clean the motorcycle with cold wa-ter and a mild detergent, after theengine has cooled down.NOTICE: Do not use warm watersince it increases the corrosiveaction of the salt. [ECA10791]

2. Apply a corrosion protection sprayon all metal, including chrome- andnickel-plated, surfaces to preventcorrosion.

After cleaning1. Dry the motorcycle with a chamois

or an absorbing cloth.2. Immediately dry the drive chain

and lubricate it to prevent it fromrusting.

WARRANTY QUESTIONS AND ANSWERS

What costs are my responsibility during the warranty period?The customer’s responsibility includes all costs of normal maintenance services, non-warranty repairs, accident and collision damages, and oil, oil filters, air filters, spark plugs, and brake shoes.

What are some examples of “abnormal” strain, neglect, or abuse?These terms are general and overlap each other in areas. Specific examples include: Running the machine out of oil, sustained high rpm, full-throttle, operating the machine with a broken or damaged part which causes another part to fail, damage or failure due to improper or careless transportation and/or tie-down. If you have any specific questions on operation or maintenance, please contact your dealer for advice.

Does the warranty cover incidental costs such as towing or transportation due toa failure?No. The warranty is limited to repair of the machine itself.

May I perform any or all of the recommended maintenance shown in the Owner’s Manual instead of having the dealer do them?Yes, if you are a qualified mechanic and follow the procedures specified in the Owner’s and Service Manual. We do recommend, however, that items requiring special tools or equipment be done by a Yamaha motorcycle dealer.

Will the warranty be void or cancelled if I do not operate or maintain my new motorcycle exactly as specified in the Owner’s Manual?No. The warranty on a new motorcycle cannot be “voided” or “cancelled.” However, if a particular failure is caused by operation or maintenance other than as described in the Owner’s Manual, that failure may not be covered under warranty.

What responsibility does my dealer have under this warranty?Each Yamaha motorcycle dealer is expected to:

Completely set up every new machine before sale.Explain the operation, maintenance, and warranty requirements to your satisfaction at the time of sale, and upon your request at any later date.Each Yamaha motorcycle dealer is held responsible for his setup, service and warranty repair work.

Is the warranty transferable to second owners?Yes. The remainder of the existing warranty can be transferred upon request. The unit has to be inspected and re-registered by an authorized Yamaha motorcycle dealer for the policy to remain effective.

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 $150 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.
