    Motorcycles are fascinating vehicles, which can give you an unsurpassed feeling of power andfreedom. However, they also impose certain limits, which you must accept; even the bestmotorcycle does not ignore the laws of physics.

    Regular care and maintenance are essential for preserving your motorcycles value and operat-ing condition. Moreover, what is true for the motorcycle is also true for the rider: good perfor-mance depends on being in good shape. Riding under the influence of medication, drugs andalcohol is, of course, out of the question. Motorcycle riders - more than car drivers - mustalways be at their mental and physical best. Under the influence of even small amounts ofalcohol, there is a tendency to take dangerous risks.

    Protective clothing is as essential for the motorcycle rider as seat belts are for car drivers andpassengers. Always wear a complete motorcycle suit (whether made of leather or tear-resistantsynthetic materials with protectors), sturdy boots, motorcycle gloves and a properly fitting hel-met. Optimum protective wear, however, should not encourage carelessness. Though full-cov-erage helmets and suits, in particular, create an illusion of total safety and protection, motorcy-clists will always be vulnerable. Riders who lack critical self-control run the risk of going toofast and are apt to take chances. This is even more dangerous in wet weather. The good motor-cyclist rides safely, predictably and defensively - avoiding all dangers, including those causedby others.

    Enjoy your ride!

    Owners are personally responsible for their vehicles condition. Your motorcycles vital functions can start todeteriorate quickly and unexpectedly, even if it remains unused (for instance, if it is exposed to the elements).Any damage, fluid leak or loss of tire pressure could have serious consequences. Therefore, it is very importantthat, in addition to a thorough visual inspection, you check the following points before each ride.

    Tips for reducing fuel consumptionYour motorcycles fuel consump-tion depends to a large extent onyour riding style. The followingtips can help reduce fuel consump-tion:8 Warm up the engine before

    riding.8 Turn off the starter (choke) as

    soon as possible.8 Shift up swiftly and avoid high

    engine speeds during accelera-tion.

    8 Do not double-clutch or rev theengine while shifting downand avoid high engine speedswith no load on the engine.

    8 Turn off the engine instead ofletting it idle for an extendedlength of time, i.e. in trafficjams, at traffic lights or rail-road crossings.

    Engine break-inThere is never a more importantperiod in the life of your motorcy-cle than the period between zeroand 1,000 km. For this reason weask that you carefully read the fol-lowing material. Because theengine is brand new, you must notput an excessive load on it for thefirst 1,000 km. The various parts inthe engine wear and polish them-selves to the correct operatingclearances. During this period, pro-longed full throttle operation, orany condition which might result inexcessive heating of the engine,must be avoided.

    EAU00443

    0 ~ 150 km Avoid operation above 1/3 throttle.Stop the engine and let it cool for 5to 10 minutes after every hour ofoperation. Vary the speed of themotorcycle from time to time. Donot operate it at one set throttleposition.

    150 ~ 500 km Avoid prolonged operation above1/2 throttle. Rev the motorcyclefreely through the gears, but donot use full throttle at any time.

    500 ~ 1,000 km Avoid cruising speeds in excess of3/4 throttle.

    InspectionThe spark plug is an important enginecomponent and is easy to inspect.The condition of the spark plug canindicate the condition of the engine.Normally, all spark plugs from thesame engine should have the samecolor on the white insulator aroundthe center electrode. The ideal colorat this point is a medium-to-light tancolor for a motorcycle that is beingridden normally. If one spark plugshows a distinctly different color,there could be something wrong withthe engine.Do not attempt to diagnose suchproblems yourself. Instead, take themotorcycle to a Yamaha dealer. Youshould periodically remove andinspect the spark plugs because heatand deposits will cause any sparkplug to slowly break down and erode.If electrode erosion becomes exces-sive, or if carbon and other depositsare excessive, you should replace thespark plug with the specified plug.

    Specified spark plug:CR6HSA (NGK) orU20FSR-U (DENSO)

    Proper loading of your motorcycleis important for several character-istics of your motorcycle, such ashandling, braking, performanceand safety. Do not carry looselypacked items that can shift.Securely pack your heaviest itemsclose to the center of the motorcy-cle, and distribute the weightevenly from side to side. Properlyadjust the suspension for yourload, and check the condition andpressure of your tires. NEVEROVERLOAD YOUR MOTORCYCLE.Make sure the total weight of thecargo, rider, passenger, and acces-sories (fairing, saddlebags, etc. ifapproved for this model) does notexceed the maximum load of themotorcycle.

    WheelsTo ensure maximum performance,long service, and safe operation,note the following:8 Always inspect the wheels

    before a ride. Check for cracks,bends or warpage of thewheel. Be sure the spokes aretight and undamaged. If anyabnormal condition exists in awheel, consult a Yamaha deal-er. Do not attempt even smallrepairs to the wheel. If a wheelis deformed or cracked, it mustbe replaced.

    8 Tires and wheels should bebalanced whenever either oneis changed or replaced. Failureto have a wheel balanced canresult in poor performance,adverse handling characteris-tics, and shortened tire life.

    8 Ride at moderate speeds afterchanging a tire since the tiresurface must first be broken infor it to develop its optimalcharacteristics.

    MOTORCYCLE CARE AND STORAGE

    7-1

    CareThe exposure of its technologymakes a motorcycle charming butalso vulnerable. Although high-quality components are used, theyare not all rust-resistant. While arusty exhaust pipe may remainunnoticed on a car, it does lookunattractive on a motorcycle.Frequent and proper care, howev-er, will keep your motorcycle look-ing good, extend its life and main-tain its performance. Moreover, thewarranty states that the vehiclemust be properly taken care of. Forall these reasons, it is recommend-ed that you observe the followingcleaning and storing precautions.

    Before cleaning1. Cover up the muffler outlets

    with plastic bags.2. Make sure that all caps and

    covers as well as all electricalcouplers and connectors,including the spark plug caps,are tightly installed.

    3. Remove extremely stubborndirt, like oil burnt onto thecrankcase, with a degreasingagent and a brush, but neverapply such products ontoseals, gaskets, sprockets, thedrive chain and wheel axles.Always rinse the dirt anddegreaser off with water.

    CleaningAfter normal useRemove dirt with warm water, aneutral detergent and a soft cleansponge, then rinse with plenty ofclean water. Use a tooth or bottlebrush for hard-to-reach parts.Tougher dirt and insects will comeoff more easily if the area is cov-ered with a wet cloth for a fewminutes before cleaning.

    ECA00010

    cC

    8 Avoid using strong acidicwheel cleaners, especially onspoked wheels. If you do usesuch products for hard-to-remove dirt, do not leave it onany longer than instructed,then thoroughly rinse it offwith water, immediately drythe area and apply a corrosionprotection spray.

    8 Improper cleaning can damagewindshields, cowlings, panelsand other plastic parts. Useonly a soft, clean cloth orsponge with mild detergentand water to clean plastic.

    8 Do not use any harsh chemicalproducts on plastic parts. Besure to avoid using cloths orsponges which have been incontact with strong or abra-sive cleaning products, solventor thinner, fuel (gasoline), rustremovers or inhibitors, brakefluid, antifreeze or electrolyte.

    8 Do not use high-pressurewashers or steam-jet cleanerssince they cause water seep-age and deterioration in thefollowing areas: seals (ofwheel bearings, swingarmbearings, forks and brakes),electric components (couplers,connectors, instruments,switches and lights), breatherhoses and vents.

    8 For motorcycles equippedwith a windshield: Do not usestrong cleaners or hardsponges as they will causedulling or scratching. Somecleaning compounds for plas-tic may leave scratches on thewindshield. Test the producton a small hidden part of thewindshield to make sure theydo not leave any marks. If thewindshield is scratched, use aquality plastic polishing com-pound after washing.

    After riding in the rain, near thesea or on salt-sprayed roadsSince sea salt or salt sprayed onthe roads in the winter areextremely corrosive in combina-tion with water, carry out the fol-lowing steps after each ride in therain, near the sea or on salt-sprayed roads. (Salt sprayed in thewinter may remain on the roadswell into spring.)

    1. Clean your motorcycle withcold water and soap after theengine has cooled down.

    ECA00012

    cC

    Do not use warm water since itincreases the corrosive action ofthe salt.

    2. Be sure to apply a corrosionprotection spray on all (evenchrome- and nickel-plated)metal surfaces to prevent cor-rosion.

    After cleaning1. Dry the motorcycle with a

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

    chain and lubricate it to pre-vent it from rusting.

    3. Use a chrome polish to shinechrome, aluminum and stain-less-steel parts, including theexhaust system. (Even thethermally induced discoloringof stainless-steel exhaust sys-tems can be removed throughpolishing.)

    4. To prevent corrosion, it is rec-ommended to apply a corro-sion protection spray on all(even chrome- and nickel-plat-ed) metal surfaces.

    5. Use spray oil as a universalcleaner to remove any remain-ing dirt.

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

    7. Wax all painted surfaces.8. Let the motorcycle dry com-

    pletely before storing it or cov-ering it.

    EWA00001

    w

    Make sure that there is no oil orwax on the brakes and tires. If nec-essary, clean the brake discs andlinings with a regular brake disccleaner or acetone, and wash thetires with warm water and mildsoap. Then, carefully test themotorcycle for its braking perfor-mance and cornering behavior.

    8 Storing the motorcycle in apoorly ventilated room or cov-ering it with a tarp while it isstill wet will allow water andhumidity to seep in and causerust.

    8 To prevent corrosion, avoiddamp cellars, stables (becauseof the presence of ammonia)and areas where strong chem-icals are stored.

    Long-termBefore storing your motorcycle forseveral months:

    1. Follow all the instructions inthe Care section of thischapter.

    2. Drain the carburetor floatchambers by loosening thedrain bolts; this will preventfuel deposits from building up.Pour the drained fuel into thefuel tank.

    3. Only for motorcycles equippedwith a fuel cock which has anOFF position: Turn the fuelcock to OFF.

    4. Fill up the fuel tank and addfuel stabilizer (if available) toprevent the fuel tank from rust-ing and the fuel from deterio-rating.

    5. Perform the following steps toprotect the cylinders, pistonrings, etc. from corrosion.

    a. Remove the spark plug capsand spark plugs.

    b. Pour a teaspoonful of engineoil into each spark plug bore.

    c. Install the spark plug caps ontothe spark plugs and place thespark plugs on the cylinderhead so that the electrodes aregrounded. (This will limitsparking during the next step.)

    d. Turn the engine over severaltimes with the starter. (Thiswill coat the cylinder wallswith oil.)

    e. Remove the spark plug capsfrom the spark plugs, installthe spark plugs and then thespark plug caps.
