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 motorcycle’s 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 vehicle’s condition. Your motorcycle’s 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.

8 Do not coast for long periods

with the engine off, and do

not tow the motorcycle a long

distance. Even with gears in

neutral, the transmission is

only properly lubricated when

the engine is running.

Inadequate lubrication may

damage the transmission.

8 Always use the clutch when

changing gears. The engine,

transmission, and driveline are

not designed to withstand the

shock of forced shifting and

can be damaged by shifting

without using the clutch.

Tips for reducing fuel consumptionYour motorcycle’s 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.

EAU00436

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.

Inspection

The 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)

handling, braking, performance

and safety. Do not carry loosely

packed items that can shift.

Securely pack your heaviest items

close to the center of the motorcy-

cle, and distribute the weight

evenly from side to side. Properly

adjust the suspension for your

load, and check the condition and

pressure of your tires. NEVER

OVERLOAD YOUR MOTORCYCLE.

Make sure the total weight of the

cargo, rider, passenger, and acces-

sories (fairing, saddlebags, etc. if

approved for this model) does not

exceed the maximum load of the

motorcycle. Operation of an over-

loaded motorcycle could cause tire

damage, an accident, or even

injury.

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.

Cleaning

After 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 acidic

wheel cleaners, especially on

spoked wheels. If you do use

such products for hard-to-

remove dirt, do not leave it on

any longer than instructed,

then thoroughly rinse it off

with water, immediately dry

the area and apply a corrosion

protection spray.

8 Improper cleaning can damage

windshields, cowlings, panels

and other plastic parts. Use

only a soft, clean cloth or

sponge with mild detergent

and water to clean plastic.

8 Do not use any harsh chemical

products on plastic parts. Be

sure to avoid using cloths or

sponges which have been in

contact with strong or abra-

sive cleaning products, solvent

or thinner, fuel (gasoline), rust

removers or inhibitors, brake

fluid, antifreeze or electrolyte.

8 Do not use high-pressure

washers or steam-jet cleaners

since they cause water seep-

age and deterioration in the

following areas: seals (of

wheel bearings, swingarm

bearings, forks and brakes),

electric components (couplers,

connectors, instruments,

switches and lights), breather

hoses and vents.

8 For motorcycles equipped

with a windshield: Do not use

strong cleaners or hard

sponges as they will cause

dulling or scratching. Some

cleaning compounds for plas-

tic may leave scratches on the

windshield. Test the product

on a small hidden part of the

windshield to make sure they

do not leave any marks. If the

windshield is scratched, use a

quality 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 it

increases the corrosive action of

the salt.

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

After cleaning

1. Dry the motorcycle with achamois or an absorbing cloth.

2. Immediately dry the drivechain 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 or

wax on the brakes and tires. If nec-

essary, clean the brake discs and

linings with a regular brake disc

cleaner or acetone, and wash the

tires with warm water and mild

soap. Then, carefully test the

motorcycle for its braking perfor-

mance and cornering behavior.

ECA00013

cC

8 Apply spray oil and wax spar-

ingly and wipe off any excess.

8 Never apply oil or wax on rub-

ber and plastic parts, but treat

them with a suitable care

product.

8 Avoid using abrasive polishing

compounds as they wear

away the paint.

NOTE:

Consult a Yamaha dealer foradvice on what products to use.

StorageShort-term

Always store your motorcycle in acool, dry place and, if necessary,protect it against dust with aporous cover.

ECA00014

cC

8 Storing the motorcycle in a

poorly ventilated room or cov-

ering it with a tarp while it is

still wet will allow water and

humidity to seep in and cause

rust.

8 To prevent corrosion, avoid

damp cellars, stables (because

of the presence of ammonia)

and areas where strong chem-

icals are stored.

Long-term

Before 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 an“OFF” 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.

EWA00003

w

When turning the engine over, be

sure to ground the spark plug elec-

trodes to prevent damage or injury

from sparking.

6. Lubricate all control cables andthe pivoting points of all leversand pedals as well as of thesidestand/centerstand.

7. Check and, if necessary, cor-rect the tire air pressure, thenraise the motorcycle so thatboth of its wheels are off theground. Alternatively, turn thewheels a little every month inorder to prevent the tires frombecoming degraded in onespot.

8. Cover up the muffler outletswith plastic bags to preventmoisture from entering.

9. Remove the battery and fullycharge it. Store it in a cool, dryplace and recharge it once amonth. Do not store the bat-tery in an excessively cold orwarm place (less than 0°C ormore than 30°C). For moreinformation, see “Battery stor-age” in the chapter “PERIODICMAINTENANCE AND MINORREPAIRS”.

NOTE:

Make any necessary repairs beforestoring the motorcycle.
