AN IMPORTANT NOTE TO PARENTS:
This motorcycle is not a toy. Before you let your child ride this motorcycle, you should understand the instructions and warn-ings in this Owner’s Manual. Then be sure your child understands and will follow them. Children differ in skills, physical abil-ities, and judgment. Some children may not be able to operate a motorcycle safely. Parents should supervise their child’suse of the motorcycle at all times. Parents should permit continued use only if they determine that the child has the ability tooperate the motorcycle safely.
INTRODUCTION
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.

Safe riding
�
Always make pre-operationchecks. Careful checks may helpprevent an accident.
�
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.
�
Many accidents involve inexperi-enced operators.
�
Make sure that the operator isqualified and that you only lendyour motorcycle to other quali-fied operators.
�
Know your skills and limits.Staying within your limits mayhelp you to avoid an accident.
�
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 un-
dercornering (insufficient lean an-gle for the speed). Never travelfaster than warranted by condi-tions.
�
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 impairment
of 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.
�
Never touch the engine or exhaustsystem during or after operation.They become very hot and cancause burns. Always wear protec-tive clothing that covers your legs,ankles, and feet.
Modifications
Modifications made to this motorcyclenot approved by Yamaha, or the re-moval of original equipment, may ren-der the motorcycle unsafe for use andmay cause severe personal injury.Modifications may also make your mo-torcycle illegal to use.

can 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 toyour 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:
Loading
�
The weight of the operator mustnot exceed 25 kg (55 lb).
�
Accessory weight should be keptas low and close to the motorcycleas possible. 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 are securely attached tothe motorcycle before riding.Check accessory mounts fre-quently.
�
Never attach any large or heavy
items to the handlebar, front fork,or front fender.
AccessoriesGenuine Yamaha accessories havebeen specifically designed for use onthis motorcycle. Since Yamaha cannottest all other accessories that may beavailable, you must personally be re-sponsible for the proper selection, in-stallation and use of non-Yamahaaccessories. Use extreme cautionwhen selecting and installing any ac-cessories.Keep these guidelines in mind formounting accessories in addition tothose provided under “Loading”.
�
Never install accessories or 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 can
create instability due to improperweight distribution or aerody-namic changes. If accessoriesare 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.
�
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 of

PRE-OPERATION CHECKS
EAU15593
The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or lossof tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual inspec-tion, to check the following points before each ride.
NOTE:
Pre-operation checks should be made each time the vehicle is used. Such an inspection can be accomplished in a very short
time; and the added safety it assures is more than worth the time involved.
WARNING
EWA11150
If any item in the Pre-operation check list is not working properly, have it inspected and repaired before operating
the vehicle.

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.
CAUTION:

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.

MOTORCYCLE CARE AND STORAGE
EAU37833
Matte color caution
CAUTION:
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.
EAU40632
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
CAUTION:
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.
CAUTION:
ECA10790
Do not use warm water since it in-creases the corrosive action of the
salt.
2. Apply a corrosion protection sprayon 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.
CAUTION:
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
