Parents should permit continued use only if they determine that thechild has the ability to operate the motorcycle safely.Your motorcycle was delivered with an adjustable speed limiter and power reduction plate. Yamaha recommends that allbeginners start off with the speed limiter adjusting screw turned in and the power reduction plate installed in the exhaust man-ifold to limit the power available while they learn. The limiter screw may be gradually turned out to increase maximum speedas the beginner becomes more familiar with operating the motorcycle. Parents should decide when to adjust the motorcyclefor more power as their youngster’s riding skills improve. Once the rider can operate with skill at the top speed permitted byadjusting the speed limiter alone, the power reduction plate can be removed. Since removal of this plate will result in a sig-nificant increase in power, turn the speed limiter back in again; adjust it out in stages as you did before.

SAFETY INFORMATION

EAU40933

Be a Responsible Owner

As 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 Riding

Perform the pre-operation checks each

time 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 foroff-road use only, therefore, it is il-legal to 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. 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 areapproaching 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 qualifiedand 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.

�

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-

SAFETY INFORMATION

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.

Protective apparel

The 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 a

hazard.

�

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 Poisoning

All 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, deadly

levels 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.

Loading

Adding accessories to your motorcyclecan adversely affect stability and han-dling if the weight distribution of the mo-torcycle is changed. To avoid thepossibility of an accident, use extremecaution when adding accessories to

SAFETY INFORMATION

your motorcycle. Use extra care whenriding a motorcycle that has added ac-cessories. Here are some generalguidelines to follow if adding accesso-ries to your motorcycle:

Operation of an overloaded vehiclecould cause an accident.

�

The weight of the operator mustnot exceed 25 kg (55 lb).

�

Accessory weight should be keptas low and close to the motorcycleas possible. Securely pack yourheaviest items as close to the cen-ter of the vehicle as possible andmake sure to distribute the weightas evenly as possible on bothsides of the motorcycle to mini-mize imbalance or instability.

�

Shifting weights can create a sud-den imbalance. Make sure that ac-cessories are securely attached tothe motorcycle before riding.Check accessory mounts fre-quently.

�

Properly adjust the suspensionfor 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.

Genuine Yamaha Accessories

Choosing 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, and Modifications

While you may find aftermarket prod-ucts similar in design and quality to

genuine 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 orcornering 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-

SAFETY INFORMATION

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

Aftermarket Tires and Rims

The tires and rims that came with your

motorcycle 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 7-12 for tirespecifications and more information onreplacing your tires.

Engine break-in

There is never a more important periodin the life of your engine than the first 5hours of riding. It is also important to ac-custom the rider to the motorcycle dur-ing this time. Please read the followinginformation carefully.Since the engine is brand new, do notput an excessive load on it for the first 5hours of operation. The various parts inthe engine wear and polish themselvesto the correct operating clearances.During this period, prolonged full-throt-tle operation or any condition that mightresult in engine overheating must beavoided. However, momentaryfull-throttle operation under load (i.e.,two to three seconds maximum) doesnot harm the engine. Each full-throttleacceleration should be followed with asubstantial rest period for the engine.To allow the engine to cool down fromthe temporary buildup of heat, cruise ata lower engine speed.After the first 5 hours of operation, thor-oughly check the motorcycle for looseparts, oil leakage and any other prob-lems. Be sure to inspect and make ad-

justments thoroughly, especiallycables. In addition, check all fittings andfasteners for looseness, and tighten ifnecessary.

NOTICE

Troubleshooting

Although Yamaha motorcycles receivea thorough inspection before shipmentfrom the factory, trouble may occur dur-ing operation. Any problem in the fuel,compression, or ignition systems, forexample, can cause poor starting andloss of power.The following troubleshooting chartrepresents a quick and easy procedurefor checking these vital systems your-self. However, should your motorcyclerequire any repair, take it to a Yamahadealer, whose skilled technicians havethe necessary tools, experience, andknow-how to service the motorcycleproperly.Use only genuine Yamaha replace-ment parts. Imitation parts may look likeYamaha parts, but they are often inferi-or, have a shorter service life and canlead to expensive repair bills.

WARNING

EWA15141

When checking the fuel system, donot smoke, and make sure there areno open flames or sparks in the ar-ea, including pilot lights from water

heaters or furnaces. Gasoline orgasoline vapors can ignite or ex-plode, causing severe injury or

property damage.

Matte color caution

NOTICE

ECA15192

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.

EAU40633

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 cleaning

1. Cover the muffler outlet with aplastic 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 and wheelaxles. Always rinse the dirt and de-greaser off with water.

Cleaning

NOTICE

ECA10771

�

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. Useonly a soft, clean cloth orsponge with mild detergent andwater to clean plastic.

�

Do not use any harsh chemicalproducts on plastic parts. Besure to avoid using cloths orsponges which have been incontact with strong or abrasive

cleaning 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 after

washing.

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 or near the seaSince sea salt is extremely corrosive,carry out the following steps after eachride in the rain or near the sea.

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 spray

on all metal, including chrome- andnickel-plated, surfaces to preventcorrosion.

After cleaning

1. Dry the motorcycle with a chamoisor an absorbing cloth.

2. Use a chrome polish to shinechrome, aluminum and stain-less-steel parts, including the ex-haust system. (Even the thermallyinduced discoloring of stain-less-steel exhaust systems can beremoved through polishing.)

3. To prevent corrosion, it is recom-mended to apply a corrosion pro-tection spray on all metal,including chrome- and nickel-plat-ed, surfaces.

4. Use spray oil as a universal clean-er to remove any remaining dirt.

5. Touch up minor paint damagecaused by stones, etc.

6. Wax all painted surfaces.7. Let the motorcycle dry completely

before storing or covering it.

Storage

Short-term

Always store your motorcycle in a cool,dry place and, if necessary, protect itagainst dust with a porous cover.

NOTICE

ECA10810

�

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-term

Before 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 “S” (stop) po-sition: Turn the fuel cock lever to

“S”.3. Drain the carburetor float chamber

by 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.)

e. Remove the spark plug capfrom the spark plug, and then
