SAFETY INFORMATION

EAU1026B

Be a Responsible Owner

As the vehicle’s owner, you are re-sponsible for the safe and proper oper-ation of your scooter.Scooters 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 be-fore riding this scooter.He or she should: Obtain thorough instructions from

a competent source on all aspectsof scooter 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.

Never operate a scooter withoutproper training or instruction. Takea training course. Beginnersshould receive training from a cer-tified instructor. Contact an autho-rized scooter dealer to find outabout the training courses nearestyou.

Safe Riding

Perform the pre-operation checkseach time you use the vehicle to makesure it is in safe operating condition.Failure to inspect or maintain the vehi-cle properly increases the possibility ofan accident or equipment damage.See page 4-1 for a list of pre-operationchecks. This scooter is designed to carry

the operator and a passenger. The failure of motorists to detect

and recognize scooters in traffic isthe predominating cause of auto-mobile/scooter accidents. Manyaccidents have been caused byan automobile driver who did notsee the scooter. Making yourself

conspicuous appears to be veryeffective in reducing the chance ofthis type of accident.Therefore:

• Wear a brightly colored jacket.• Use extra caution when you are

approaching and passingthrough intersections, since in-tersections are the most likelyplaces for scooter accidents tooccur.

• Ride where other motorists cansee you. Avoid riding in anothermotorist’s blind spot.

• Never maintain a scooter with-out proper knowledge. Contactan authorized scooter dealer toinform you on basic scootermaintenance. Certain mainte-nance can only be carried outby certified staff.


SAFETY INFORMATION

1-2

1 Many accidents involve inexperi-

enced operators. In fact, many op-erators who have been involved inaccidents do not even have a cur-rent driver’s license.• Make sure that you are qualified

and that you only lend yourscooter 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 scooter wherethere is no traffic until you havebecome thoroughly familiar withthe scooter and all of its con-trols.

Many accidents have beencaused by error of the scooter op-erator. A typical error made by theoperator is veering wide on a turndue to excessive speed or under-cornering (insufficient lean anglefor the speed).• Always obey the speed limit and

never travel faster than warrant-ed by road and traffic condi-tions.

• Always signal before turning orchanging lanes. Make sure thatother motorists can see you.

The posture of the operator andpassenger is important for propercontrol.• The operator should keep both

hands on the handlebar andboth feet on the operator foot-rests during operation to main-tain control of the scooter.

• The passenger should alwayshold onto the operator, the seatstrap or grab bar, if equipped,with both hands and keep bothfeet on the passenger footrests.Never carry a passenger unlesshe or she can firmly place bothfeet on the passenger footrests.

Never ride under the influence ofalcohol or other drugs.

This scooter is designed for on-road use only. It is not suitable foroff-road use.

Protective Apparel

The majority of fatalities from scooteraccidents are the result of head inju-ries. The use of a safety helmet is thesingle most critical factor in the pre-vention 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 ahazard.

The use of a jacket, substantialshoes, trousers, gloves, etc., is ef-fective in preventing or reducingabrasions or lacerations.

Never wear loose-fitting clothes,otherwise they could catch on thecontrol levers or wheels and causeinjury 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 causeburns.

A passenger should also observethe above precautions.


SAFETY INFORMATION

1-3

1Avoid Carbon Monoxide Poisoning

All engine exhaust contains carbonmonoxide, a deadly gas. Breathingcarbon monoxide can cause head-aches, dizziness, drowsiness, nausea,confusion, and eventually death.Carbon Monoxide is a colorless, odor-less, tasteless gas which may be pres-ent even if you do not see or smell anyengine exhaust. Deadly levels of car-bon monoxide can collect rapidly andyou can quickly be overcome and un-able to save yourself. Also, deadly lev-els of carbon monoxide can linger forhours or days in enclosed or poorlyventilated areas. If you experience anysymptoms of carbon monoxide poi-soning, leave the area immediately, getfresh air, and SEEK MEDICAL TREAT-MENT. Do not run engine indoors. Even if

you 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 or cargo to yourscooter can adversely affect stabilityand handling if the weight distributionof the scooter is changed. To avoid thepossibility of an accident, use extremecaution when adding cargo or acces-sories to your scooter. Use extra carewhen riding a scooter that has addedcargo or accessories. Here, along withthe information about accessories be-low, are some general guidelines to fol-low if loading cargo to your scooter:The total weight of the operator, pas-senger, accessories and cargo mustnot exceed the maximum load limit.Operation of an overloaded vehicle

could cause an accident.

When loading within this weight limit,keep the following in mind: Cargo and accessory weight

should be kept as low and close tothe scooter as possible. Securelypack your heaviest items as closeto the center of the vehicle as pos-sible and make sure to distributethe weight as evenly as possibleon both sides of the scooter tominimize imbalance or instability.

Shifting weights can create a sud-den imbalance. Make sure thataccessories and cargo are se-curely attached to the scooter be-fore riding. Check accessorymounts and cargo restraints fre-quently.• Properly adjust the suspension

for your load (suspension-ad-justable models only), andcheck the condition and pres-sure of your tires.

• Never attach any large or heavyitems to the handlebar, frontfork, or front fender. Such itemscan create unstable handling ora slow steering response.

Maximum load:YP400R 185 kg (408 lb)YP400RA 181 kg (399 lb)

1 This vehicle is not designed to

pull a trailer or to be attached to

a sidecar.

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 connectionto Yamaha manufacture parts and ac-cessories or offer other modificationsfor Yamaha vehicles. Yamaha is not ina position to test the products thatthese aftermarket 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 togenuine Yamaha accessories, recog-

nize that some aftermarket accesso-ries or modifications are not suitablebecause of potential safety hazards toyou or others. Installing aftermarketproducts or having other modificationsperformed to your vehicle that changeany of the vehicle’s design or operationcharacteristics can put you and othersat greater risk of serious injury ordeath. You are responsible for injuriesrelated to changes in the vehicle.Keep the following guidelines in mind,as well as those provided under “Load-ing” when mounting accessories. Never install accessories or carry

cargo that would impair the per-formance of your scooter. Careful-ly inspect the accessory beforeusing it to make sure that it doesnot in any way reduce groundclearance or cornering clearance,limit suspension travel, steeringtravel or control operation, or ob-scure lights or reflectors.• Accessories fitted to the han-

dlebar or the front fork area cancreate instability due to improp-er weight distribution or aerody-namic changes. If accessories

are 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 scooter due to aerodynamiceffects. Wind may attempt to liftthe scooter, or the scooter maybecome unstable in crosswinds. These accessories mayalso cause instability whenpassing or being passed by lar-ge vehicles.

• Certain accessories can dis-place the operator from his orher normal riding position. Thisimproper position limits thefreedom of movement of theoperator and may limit controlability, therefore, such accesso-ries are not recommended.

Use caution when adding electri-cal accessories. If electrical ac-cessories exceed the capacity ofthe scooter’s electrical system, anelectric failure could result, whichcould cause a dangerous loss oflights or engine power.


SAFETY INFORMATION

1Aftermarket Tires and Rims

The tires and rims that came with yourscooter were designed to match theperformance capabilities and to pro-vide the best combination of handling,braking, and comfort. Other tires, rims,sizes, and combinations may not beappropriate. Refer to page 6-21 for tirespecifications and more information onreplacing your tires.

Transporting the Scooter

Be sure to observe following instruc-tions before transporting the scooter inanother vehicle. Remove all loose items from the

scooter. Point the front wheel straight

ahead on the trailer or in the truckbed, and choke it in a rail to pre-vent movement.

Secure the scooter with tie-downsor suitable straps that are at-tached to solid parts of the scoot-er, such as the frame or upperfront fork triple clamp (and not, forexample, to rubber-mounted han-dlebars or turn signals, or partsthat could break). Choose the lo-

cation for the straps carefully sothe straps will not rub againstpainted surfaces during transport.

The suspension should be com-pressed somewhat by the tie-downs, if possible, so that thescooter will not bounce exces-sively during transport.

EAU57600

Further safe-riding points Be sure to signal clearly when

making turns. Braking can be extremely difficult

on a wet road. Avoid hard braking,because the scooter could slide.Apply the brakes slowly whenstopping on a wet surface.

Slow down as you approach acorner or turn. Once you havecompleted a turn, accelerateslowly.

Be careful when passing parkedcars. A driver might not see youand open a door in your path.

Railroad crossings, streetcar rails,iron plates on road constructionsites, and manhole covers be-come extremely slippery whenwet. Slow down and cross themwith caution. Keep the scooter up-right, otherwise it could slide outfrom under you.

The brake pads or linings couldget wet when you wash the scoot-er. After washing the scooter,check the brakes before riding.


SAFETY INFORMATION

Immobilizer system

This vehicle is equipped with an immo-bilizer system to help prevent theft byre-registering codes in the standardkeys. This system consists of the fol-lowing: a code re-registering key (with a

red bow) two standard keys (with a black

bow) that can be re-registeredwith new codes

a transponder (which is installed inthe code re-registering key)

an immobilizer unit an ECU

an immobilizer system indicatorlight (See page 3-4.)

The key with the red bow is used toregister codes in each standard key.Since re-registering is a difficult pro-cess, take the vehicle along with allthree keys to a Yamaha dealer to havethem re-registered. Do not use the keywith the red bow for driving. It shouldonly be used for re-registering thestandard keys. Always use a standardkey for driving.

NOTICEECA11822

DO NOT LOSE THE CODE RE-

REGISTERING KEY! CONTACT

YOUR DEALER IMMEDIATELY

new codes in the standard keys

is impossible. The standard

keys can still be used to start

the vehicle, however if code re-

registering is required (i.e., if a

new standard key is made or all

keys are lost) the entire immobi-

lizer system must be replaced.

Therefore, it is highly recom-

mended to use either standard

key and keep the code re-regis-

tering key in a safe place.

Do not submerse any key in wa-

ter.

Do not expose any key to exces-

sively high temperatures.

Do not place any key close to

magnets (this includes, but not

limited to, products such as

speakers, etc.).

Do not place items that transmit

electrical signals close to any

key.

Do not place heavy items on any

key.

Do not grind any key or alter its

shape.

Do not disassemble the plastic

part of any key.

Do not put two keys of any im-

mobilizer system on the same

Be sure to turn the key to “ON” be-fore using the “SELECT” and “RE-SET” buttons.

When the key is turned to “ON”, allof the display segments of themulti-function display will appearone after the other and then disap-pear, in order to test the electricalcircuit.

For the UK, the distance traveledis displayed in miles and the tem-perature reading is displayed in°C.

For other countries, the distancetraveled is displayed in kilometersand the temperature reading isdisplayed in °C.

Odometer and tripmeter modes

Pushing the “SELECT” button switch-es the display between the odometermode “Odo” and the tripmeter modes“Trip” in the following order:Odo → Trip 1 → Trip 2 → Odo

When approximately 2.0 L (0.53 USgal, 0.44 Imp.gal) of fuel remains in thefuel tank, the bottom segment of thefuel meter will start flashing, and thedisplay will automatically change to thefuel reserve tripmeter mode “Trip F”and start counting the distance trav-eled from that point. In that case, push-ing the “SELECT” button switches thedisplay between the various tripmeterand odometer modes in the followingorder:Trip F → Trip 1 → Trip 2 → Odo → TripF

To reset a tripmeter, select it by push-ing the “SELECT” button until “Trip” or“Trip F” , push the “RESET” button forat least one second. If you do not reset

the fuel reserve tripmeter manually, itwill reset itself automatically and thedisplay will return to the prior mode af-ter refueling and traveling 5 km (3 mi).

TIP

The display cannot be changed backto “Trip F” after pushing the “RESET”button.

Fuel meter

With the key in the “ON” position, thefuel meter indicates the amount of fuelin the fuel tank. The display segmentsof the fuel meter disappear towards“E” (Empty) as the fuel level decreases.When the fuel level reaches the bottomsegment near “E”, the bottom segmentwill flash. Refuel as soon as possible.

ABS (for ABS models)The Yamaha ABS (Anti-lock BrakeSystem) features a dual electronic con-trol system, which acts on the front andrear brakes independently.Operate the brakes with ABS as youwould conventional brakes. If the ABSis activated, a pulsating sensation maybe felt at the brake levers. In this situa-tion, continue to apply the brakes andlet the ABS work; do not “pump” thebrakes as this will reduce braking ef-fectiveness.

WARNING

EWA16051

Always keep a sufficient distance

from the vehicle ahead to match the

riding speed even with ABS.

The ABS performs best with

long braking distances.

On certain surfaces, such as

rough or gravel roads, the brak-

ing distance may be longer with

the ABS than without.

The ABS is monitored by an ECU,which will revert the system to conven-tional braking if a malfunction occurs.

TIP

The ABS performs a self-diagno-sis test each time the vehicle firststarts off after the key is turned to“ON” and the vehicle has traveledat a speed of 10 km/h (6 mi/h) orhigher. During this test, a “click-ing” noise can be heard from thefront of the vehicle, and if eitherbrake lever is even slightly ap-plied, a vibration can be felt at thelever, but these do not indicate amalfunction.

This ABS has a test mode whichallows the owner to experiencethe pulsation at the brake leverswhen the ABS is operating. How-ever, special tools are required, soplease consult your Yamaha deal-er when performing this test.

WARNING

EWA10882

Gasoline and gasoline vapors are

extremely flammable. To avoid fires

and explosions and to reduce the

risk of injury when refueling, follow

these instructions.

1. Before refueling, turn off the en-gine and be sure that no one is sit-ting on the vehicle. Never refuelwhile smoking, or while in the vi-cinity of sparks, open flames, orother sources of ignition such asthe pilot lights of water heatersand clothes dryers.

2. Do not overfill the fuel tank. Whenrefueling, be sure to insert thepump nozzle into the fuel tank fillerhole. Stop filling when the fuelreaches the bottom of the fillertube. Because fuel expands whenit heats up, heat from the engine orthe sun can cause fuel to spill outof the fuel tank.

3. Wipe up any spilled fuel immedi-ately. NOTICE: Immediately

wipe off spilled fuel with a clean,

dry, soft cloth, since fuel may

deteriorate painted surfaces or

plastic parts. [ECA10072]

pery when wet. Therefore, slow

down when approaching such

areas and cross them with cau-

tion.

Keep in mind that braking on a

wet road is much more difficult.

Ride slowly down a hill, as brak-

ing downhill can be very diffi-

cult.

Checking the spark plugThe spark plug is an important enginecomponent, which is easy to check.Since heat and deposits will cause anyspark plug to slowly erode, the sparkplug should be removed and checkedin accordance with the periodic main-tenance and lubrication chart. In addi-tion, the condition of the spark plugcan reveal the condition of the engine.

To remove the spark plug

1. Place the vehicle on the center-stand

2. Open the seat. (See page 3-16.)3. Remove the rear storage com-

partment by removing the bolts.

4. Remove the spark plug cap.

5. Remove the spark plug as shown,with the spark plug wrench includ-ed in the owner’s tool kit.

To check the spark plug

1. Check that the porcelain insulatoraround the center electrode of thespark plug is a medium-to-lighttan (the ideal color when the vehi-cle is ridden normally).

TIP

If the spark plug shows a distinctly dif-ferent color, the engine could be oper-ating improperly. Do not attempt todiagnose such problems yourself. In-stead, have a Yamaha dealer checkthe vehicle.

2. Check the spark plug for electrodeerosion and excessive carbon orother deposits, and replace it ifnecessary.

3. Measure the spark plug gap with awire thickness gauge and, if nec-essary, adjust the gap to specifi-cation.

Tire information

This model is equipped with tubelesstires.Tires age, even if they have not beenused or have only been used occasion-ally. Cracking of the tread and sidewallrubber, sometimes accompanied bycarcass deformation, is an evidence ofageing. Old and aged tires shall bechecked by tire specialists to ascertaintheir suitability for further use.After extensive tests, only the tires list-ed below have been approved for thismodel by Yamaha Motor Co., Ltd.

WARNING

EWA10472

Have a Yamaha dealer replace

excessively worn tires. Besides

being illegal, operating the vehi-

cle with excessively worn tires

decreases riding stability and

can lead to loss of control.

The replacement of all wheel

and brake-related parts, includ-

ing the tires, should be left to a

Yamaha dealer, who has the

necessary professional knowl-

edge and experience to do so.

Ride at moderate speeds after

changing a tire since the tire

surface must first be “broken

in” for it to develop its optimal

characteristics.

EAU21995

Cast wheelsTo maximize the performance, durabil-ity, and safe operation of your vehicle,note the following points regarding thespecified wheels. The wheel rims should be

checked for cracks, bends, warp-age or other damage before eachride. If any damage is found, havea Yamaha dealer replace thewheel. Do not attempt even thesmallest repair to the wheel. A de-formed or cracked wheel must bereplaced.

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.

A soft or spongy feeling in the brake

lever can indicate the presence of

air in the hydraulic system. If there is

air in the hydraulic system, have a

Yamaha dealer bleed the system be-

fore operating the vehicle. Air in the

hydraulic system will diminish the

braking performance, which may re-

sult in loss of control and an acci-

dent.

WARNING

EWA16011

Improper maintenance can result in

loss of braking ability. Observe

these precautions:

Insufficient brake fluid may al-

low air to enter the brake sys-

tem, reducing braking

performance.

Clean the filler cap before re-

moving. Use only DOT 4 brake

fluid from a sealed container.

Use only the specified brake flu-

id; otherwise, the rubber seals

may deteriorate, causing leak-

age.

Refill with the same type of

brake fluid. Adding a brake fluid

other than DOT 4 may result in a

harmful chemical reaction.

Be careful that water or dust

does not enter the brake fluid

reservoir when refilling. Water

will significantly lower the boil-

ing point of the fluid and may re-

sult in vapor lock, and dirt may

clog the ABS hydraulic unit

valves.

NOTICEECA17641

Brake fluid may damage painted

surfaces or plastic parts. Always

clean up spilled fluid immediately.

As the brake pads wear, it is normal forthe brake fluid level to gradually godown. A low brake fluid level may indi-cate worn brake pads and/or brakesystem leakage; therefore, be sure tocheck the brake pads for wear and thebrake system for leakage. If the brake

fluid level goes down suddenly, have aYamaha dealer check the cause beforefurther riding.

Matte color caution

NOTICEECA15193

Some models are equipped with

matte colored finished parts. Be

sure to consult a Yamaha dealer for

advice on what products to use be-

fore cleaning the vehicle. Using a

brush, harsh chemical products or

cleaning compounds when cleaning

these parts will scratch or damage

their surface. Wax also should not

be applied to any matte colored fin-

ished parts.

EAU26096

CareWhile the open design of a scooter re-veals the attractiveness of the technol-ogy, it also makes it more vulnerable.Rust and corrosion can develop even ifhigh-quality components are used. Arusty exhaust pipe may go unnoticedon a car, however, it detracts from theoverall appearance of a scooter. Fre-quent and proper care does not onlycomply with the terms of the warranty,but it will also keep your scooter look-ing good, extend its life and optimizeits performance.

Before cleaning

1. Cover the muffler outlet with aplastic bag after the engine hascooled down.

2. Make sure that all caps and cov-ers as well as all electrical cou-plers and connectors, includingthe spark 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 andwheel axles. Always rinse the dirtand degreaser off with water.

Cleaning

NOTICEECA10784

Avoid using strong acidic wheel

cleaners, especially on spoked

wheels. If such products are

used on hard-to-remove dirt, do

not leave the cleaner on the af-

fected area any longer than in-

structed. Also, thoroughly rinse

the area off with water, immedi-

ately dry it, and then apply a cor-

rosion protection spray.

Improper cleaning can damage

plastic parts (such as cowlings,

panels, windshields, headlight

lenses, meter lenses, etc.) and

the mufflers. Use only a soft,

clean cloth or sponge with wa-

ter to clean plastic. However, if

the plastic parts cannot be thor-

oughly cleaned with water, di-

luted mild detergent with water

may be used. Be sure to rinse



7-2

7

off any detergent residue using

plenty of water, as it is harmful

to plastic parts.

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 abrasive

cleaning products, solvent or

thinner, fuel (gasoline), rust re-

movers or inhibitors, brake fluid,

antifreeze or electrolyte.

Do not use high-pressure wash-

ers or steam-jet cleaners since

they cause water seepage and

deterioration in the following ar-

eas: seals (of wheel and swing-

arm bearings, fork and brakes),

electric components (couplers,

connectors, instruments,

switches and lights), breather

hoses and vents.

For scooters equipped with a

windshield: Do not use strong

cleaners or hard sponges as

they will cause dulling or

scratching. Some cleaning

compounds for plastic may

leave scratches on the wind-

shield. Test the product on a

small hidden part of the wind-

shield to make sure that it does

not leave any marks. If the wind-

shield is scratched, use a quality

plastic polishing compound af-

ter 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, near the sea oron salt-sprayed roadsSince sea salt or salt sprayed on theroads during winter are extremely cor-rosive in combination with water, carryout the following steps after each ridein the rain, near the sea or on salt-sprayed roads.

TIP

Salt sprayed on roads in the wintermay remain well into spring.

1. Clean the scooter with cold waterand a mild detergent after the en-gine has cooled down. NOTICE:Do not use warm water since it

increases the corrosive action

of the salt. [ECA10792]

2. Apply a corrosion protection sprayon all metal, including chrome-and nickel-plated, surfaces to pre-vent corrosion.

Cleaning the windshieldAvoid using any alkaline or strong acidcleaner, gasoline, brake fluid, or anyother solvent. Clean the windshieldwith a cloth or sponge dampened witha mild detergent, and then wash it offthoroughly with water. For additionalcleaning, use Yamaha WindshieldCleaner or another high-quality wind-shield cleaner. Some cleaning com-pounds for plastics may leavescratches on the windshield. Beforeusing such cleaners, test an area of the



7-3

7

windshield which does not affect yourvisibility and which cannot be easilyrecognized.

After cleaning

1. Dry the scooter with a chamois oran absorbing cloth.

2. Use a chrome polish to shinechrome, aluminum and stainless-steel parts, including the exhaustsystem. (Even the thermally in-duced discoloring of stainless-steel exhaust systems can be re-moved 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 scooter dry completely be-

fore storing or covering it.

WARNING

EWA10943

Contaminants on the brakes or tires

Storage

Short-term

Always store your scooter in a cool, dryplace and, if necessary, protect itagainst dust with a porous cover. Besure the engine and the exhaust sys-tem are cool before covering thescooter.

NOTICEECA10821

Storing the scooter in a poorly

ventilated room or covering it

with a tarp, while it is still wet,

will allow water and humidity to

seep in and cause rust.

To prevent corrosion, avoid

damp cellars, stables (because

of the presence of ammonia)

and areas where strong chemi-

cals are stored.

Long-term

Before storing your scooter for severalmonths:

1. Follow all the instructions in the“Care” section of this chapter.

2. Fill up the fuel tank and add fuelstabilizer (if available) to preventthe fuel tank from rusting and thefuel from deteriorating.

3. Perform the following steps toprotect 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 theninstall the spark plug and thespark plug cap. WARNING! To

prevent damage or injury

from sparking, make sure to

ground the spark plug elec-

trodes while turning the en-

gine over. [EWA10952]

4. Lubricate all control cables andthe pivoting points of all levers andpedals as well as of the side-stand/centerstand.

5. Check and, if necessary, correctthe tire air pressure, and then liftthe scooter so that both of itswheels are off the ground. Alterna-tively, turn the wheels a little everymonth in order to prevent the tiresfrom becoming degraded in onespot.

6. Cover the muffler outlet with aplastic bag to prevent moisturefrom entering it.

7. Remove the battery and fully char-ge it. Store it in a cool, dry placeand charge it once a month. Donot store the battery in an exces-sively cold or warm place [lessthan 0 °C (30 °F) or more than 30°C (90 °F)]. For more informationon storing the battery, see page6-29.
