WARNINGBecome thoroughly familiarwith all operating controls andtheir functions before riding.Consult a Yamaha dealer re-garding any control or functionthat you do not thoroughly un-derstand.Never start the engine or oper-ate it in a closed area for anylength of time. Exhaust fumesare poisonous, and inhalingthem can cause loss of con-sciousness and death within ashort time. Always make surethat there is adequate ventila-tion.Before starting out, make surethat the sidestand is up. If thesidestand is not raised com-pletely, it could contact theground and distract the opera-tor, resulting in a possible lossof control.

EAU03818*

Starting the engine In order for the ignition circuit cut-offsystem to enable starting, one of thefollowing conditions must be met:

� The transmission is in the neutralposition.

� The transmission is in gear withthe clutch lever pulled and thesidestand up.

Tips for reducing fuel consumption Fuel consumption depends largely onyour riding style. Consider the followingtips to reduce fuel consumption:

� Thoroughly warm up the engine.� Turn the starter (choke) off as

soon as possible.� Shift up swiftly, and avoid high en-

gine speeds during acceleration.� Do not rev the engine while shift-

ing down, and avoid high enginespeeds with no load on the engine.

� Turn the engine off instead of let-ting it idle for an extended lengthof time (e.g., in traffic jams, at traf-fic lights or at railroad crossings).

� Brand-new tires can have a rela-tively poor grip on certain roadsurfaces until they have been“broken in”. Therefore, it is ad-visable before doing anyhigh-speed riding to ride con-servatively for approximately100 km after installing a newtire.

� The tires must be warmed upbefore a high-speed run.

� Always adjust the tire air pres-sure according to the operatingconditions.

EAU03773

Cast wheels To maximize the performance, durabil-ity, and safe operation of your motor-cycle, note the following pointsregarding the specified wheels.

� The wheel rims should be checkedfor cracks, bends or warpage be-fore each ride. If any damage isfound, have a Yamaha dealer re-place the wheel. Do not attempteven the smallest repair to thewheel. A deformed or crackedwheel must be replaced.

� The wheel should be balancedwhenever either the tire or wheelhas been changed or replaced. Anunbalanced wheel can result inpoor performance, adverse han-dling characteristics, and a short-ened tire life.

� Ride at moderate speeds afterchanging a tire since the tire sur-face must first be “broken in” for itto develop its optimal characteris-tics.

bserve these precautions:� When checking the fluid level,

make sure that the top of the brakefluid reservoir is level.

� Use only the recommended quali-ty brake 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.

� Be careful that water does not en-ter the brake fluid reservoir whenrefilling. Water will significantlylower the boiling point of the fluidand may result in vapor lock.

� Brake fluid may deteriorate paint-ed surfaces or plastic parts. Al-ways clean up spilled fluidimmediately.

� As the brake pads wear, it is nor-mal for the brake fluid level togradually go down. However, if thebrake fluid level goes down sud-denly, have a Yamaha dealercheck the cause.

re ile the open design of a motorcycleals the attractiveness of the tech-gy, it also makes it more vulnera- Rust and corrosion can developn if high-quality components ared. A rusty exhaust pipe may go un-ced on a car, however, it detracts the overall appearance of a

torcycle. Frequent and proper cares not only comply with the terms ofwarranty, but it will also keep your

torcycle looking good, extend its life 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 caps, 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 anddegreaser off with water.

� 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, switch-es and lights), breather hosesand vents.

� For motorcycles equipped witha windshield: Do not use strongcleaners or hard sponges asthey will cause dulling orscratching. Some cleaningcompounds for plastic mayleave scratches on the wind-shield. Test the product on asmall hidden part of the wind-shield to make sure that it doesnot leave any marks. If the wind-shield is scratched, use a quali-ty plastic polishing compoundafter 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.

ort-termways store your motorcycle in a cool,y place and, if necessary, protect itainst dust with a porous cover.

ECA00014

AUTION:� Storing the motorcycle in a

poorly 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 cylinders, piston rings, etc.from corrosion.

Alterna-tively, turn the wheels a little everymonth in order to prevent the tiresfrom becoming degraded in onespot.Cover the muffler outlet with aplastic bag to prevent moisturefrom entering it.Remove the battery and fullycharge it. Store it in a cool, dryplace and charge it once a month.Do not store the battery in an ex-cessively cold or warm place [lessthan 0 °C or more than 30 °C.
