TABLE OF CONTENTS

SAFETY INFORMATION

SCOOTERS ARE SINGLE TRACK VEHICLES. THEIR SAFE USE AND

OPERATION ARE DEPENDENT UPON THE USE OF PROPER RIDING TECHNIQUES AS WELL AS THE EXPERTISE OF THE OPERATOR. EVERY OPERATOR SHOULD KNOW THE FOLLOWING REQUIREMENTS BEFORE RIDING THIS SCOOTER. HE OR SHE SHOULD:

● OBTAIN THOROUGH INSTRUC-

TIONS FROM A COMPETENT SOURCE ON ALL ASPECTS OF SCOOTER OPERATION.

● OBSERVE THE WARNINGS AND

MAINTENANCE REQUIREMENTS IN THE OWNER’S MAN- UAL.

● OBTAIN QUALIFIED TRAINING

IN SAFE AND PROPER RIDING TECHNIQUES.

● OBTAIN PROFESSIONAL TECH-

NICAL SERVICE AS INDICATED BY THE OWNER’S MANUAL AND/OR WHEN MADE NECESSARY BY MECHANICAL CONDITIONS.

EAU10260

Safe riding

● Always make pre-operation

checks. Careful checks may help prevent an accident.

● This scooter is designed to carry

the operator and passenger.

● The failure of motorists to detect

and recognize scooters in traffic is the predominating cause of automobile/scooter accidents. Many accidents have been caused by an automobile driver who did not see the scooter. Making yourself conspicuous appears to be very effective in reducing the chance of this type of accident.

Therefore:

• Wear a brightly colored jacket.

• Use extra caution when ap-

proaching and passing through intersections, since intersections are the most likely places for scooter accidents to occur.

• Ride where other motorists can see you. Avoid riding in another motorist’s blind spot.

● Many accidents involve inexperi-

enced operators. In fact, many operators who have been involved in accidents do not even have a current driver’s license.

• Make sure that you are qualified and that you only lend your scooter to other qualified operators.

• Know your skills and limits. Staying within your limits may help you to avoid an accident.

• We recommend that you practice riding your scooter where there is no traffic until you have become thoroughly familiar with the scooter and all of its controls.

● Many accidents have been caused

by error of the scooter operator. A typical error made by the operator is veering wide on a turn due to EXCESSIVE SPEED or undercornering (insufficient lean angle for the speed).

• Always obey the speed limit and never travel faster than warranted by road and traffic conditions.

1-1

SAFETY INFORMATION

• Always signal before turning or changing lanes. Make sure that other motorists can see you.

● The posture of the operator and

passenger is important for proper control.

• The operator should keep both hands on the handlebar and both feet on the footboard during operation to maintain control of the scooter.

• The passenger should always hold onto the operator, the seat strap or grab bar, if equipped, with both hands and keep both feet on the passenger footrests.

• Never carry a passenger unless he or she can firmly place both feet on the passenger footrests.

● Never ride under the influence of

alcohol or other drugs.

● This scooter is designed for on-

road use only. It is not suitable for off-road use.

Protective apparel

The majority of fatalities from scooter accidents are the result of head injuries. The use of a safety helmet is the single most critical factor in the prevention or reduction of head injuries.

● Always wear an approved helmet.

● Wear a face shield or goggles.

Wind in your unprotected eyes could contribute to an impairment of vision which could delay seeing a hazard.

● The use of a jacket, substantial

shoes, trousers, gloves, etc., is effective in preventing or reducing abrasions or lacerations.

● Never wear loose-fitting clothes,

otherwise they could catch on the control levers or wheels and cause injury or an accident.

● Never touch the engine or exhaust

system during or after operation. They become very hot and can cause burns. Always wear protective clothing that covers your legs, ankles, and feet.

● Passengers should also observe

the above precautions.

1-2

Modifications

Modifications made to this scooter not approved by Yamaha, or the removal of original equipment, may render the scooter unsafe for use and may cause severe personal injury. Modifications may also make your scooter illegal to use.

Loading and accessories

Adding accessories or cargo to your scooter can adversely affect stability and handling if the weight distribution of the scooter is changed. To avoid the possibility of an accident, use extreme caution when adding cargo or accessories to your scooter. Use extra care when riding a scooter that has added cargo or accessories. Here are some general guidelines to follow if loading cargo or adding accessories to your scooter: Loading The total weight of the operator, passenger, accessories and cargo must not exceed the maximum load limit of 185 kg (408 lb). When loading within this weight limit, keep the following in mind:

SAFETY INFORMATION

● Cargo and accessory weight

should be kept as low and close to the scooter as possible. Make sure

to distribute the weight as evenly as possible on both sides of the scooter to minimize imbalance or instability.

● Shifting weights can create a sud-

den imbalance. Make sure that accessories and cargo are securely attached to the scooter before riding. Check accessory mounts and cargo restraints frequently.

● Never attach any large or heavy

items to the handlebar, front fork, or front fender. Such items can create unstable handling or a slow

steering response. Accessories Genuine Yamaha accessories have been specifically designed for use on this scooter. Since Yamaha cannot test all other accessories that may be available, you must personally be responsible for the proper selection, installation and use of non-Yamaha accessories. Use extreme caution when selecting and installing any accessories.

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 performance of your scooter. Carefully inspect the accessory before using it to make sure that it does not in any way reduce ground clearance or cornering clearance, limit suspension travel, steering travel or control operation, or obscure lights or reflectors.

• Accessories fitted to the handlebar or the front fork area can create instability due to improper weight distribution or aerodynamic changes. If accessories are added to the handlebar or front fork area, they must be as lightweight as possible and should be kept to a minimum.

• Bulky or large accessories may seriously affect the stability of the scooter due to aerodynamic effects. Wind may attempt to lift the scooter, or the scooter may become unstable in cross winds. These accessories may

1-3

also cause instability when passing or being passed by large vehicles.

• Certain accessories can displace the operator from his or her normal riding position. This improper position limits the freedom of movement of the operator and may limit control ability, therefore, such accessories are not recommended.

● Use caution when adding electri-

cal accessories. If electrical accessories exceed the capacity of the scooter’s electrical system an electric failure could result, which could cause a dangerous loss of lights or engine power.

Gasoline and exhaust gas

● GASOLINE IS HIGHLY FLAMMA-

BLE:

• Always turn the engine off when refueling.

• Take care not to spill any gasoline on the engine or exhaust system when refueling.

• Never refuel while smoking or in the vicinity of an open flame.

SAFETY INFORMATION

● Never start the engine or let it run

for any length of time in a closed area. The exhaust fumes are poisonous and may cause loss of consciousness and death within a short time. Always operate your scooter in an area that has adequate ventilation.

● Always turn the engine off before

leaving the scooter unattended and remove the key from the main switch. When parking the scooter, note the following:

• The engine and exhaust system may be hot, therefore, park the scooter in a place where pedestrians or children are not likely to touch these hot areas.

• Do not park the scooter on a slope or soft ground, otherwise it may fall over.

• Do not park the scooter near a flammable source (e.g., a kerosene heater, or near an open flame), otherwise it could catch fire.

● If you should swallow any gaso-

line, inhale a lot of gasoline vapor, or allow gasoline to get into your

eyes, see your doctor immediately. If any gasoline spills on your skin or clothing, immediately wash the affected area with soap and water and change your clothes.

1-4

EAU10370

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 when stopping on a wet surface.

● Slow down as you approach a cor-

ner or turn. Once you have completed a turn, accelerate slowly.

● Be careful when passing parked

cars. A driver might not see you and open a door in your path.

● Railroad crossings, streetcar rails,

iron plates on road construction sites, and manhole covers become extremely slippery when wet. Slow down and cross them with caution. Keep the scooter upright, otherwise it could slide out from under you.

● The brake pads could get wet

when you wash the scooter. After washing the scooter, check the brakes before riding.

SAFETY INFORMATION

● Always wear a helmet, gloves,

trousers (tapered around the cuff and ankle so they do not flap), and

a bright colored jacket.

● Do not carry too much luggage on

the scooter. An overloaded scooter is unstable.

PRE-OPERATION CHECKS

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 loss of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual inspection, 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

If any item in the Pre-operation check list is not working properly, have it inspected and repaired before operating the vehicle.

OPERATION AND IMPORTANT RIDING POINTS

Engine break-in

There is never a more important period in the life of your engine than the period between 0 and 1000 km (600 mi). For this reason, you should read the following material carefully. Since the engine is brand new, do not put an excessive load on it for the first 1000 km (600 mi). The various parts in the engine wear and polish themselves to the correct operating clearances. During this period, prolonged full-throt-

tle operation or any condition that might result in engine overheating must be avoided.

0–150 km (0–90 mi)

Avoid prolonged operation above 1/3 throttle. After every hour of operation, stop the engine, and then let it cool for five to ten minutes. Vary the engine speed from time to time. Do not operate the engine at one set throttle position.

EAU16830

EAU17150

150–500 km (90–300 mi)

Avoid prolonged operation above 1/2 throttle. Rev the engine freely through the gears, but do not use full throttle at any time.

Avoid prolonged operation above 3/4 throttle.

ECA10370

CAUTION:

After 1000 km (600 mi) of operation, the transmission oil must be changed.

1000 km (600 mi) and beyond

Avoid prolonged full-throttle operation. Vary the engine speed occasionally.

ECA10270

CAUTION:

If any engine trouble should occur during the engine break-in period, immediately have a Yamaha dealer check the vehicle.

EAU17211

Parking

When parking, stop the engine, and then remove the key from the main switch.

Checking the spark plug

The spark plug is an important engine component, which should be checked periodically, preferably by a Yamaha dealer. Since heat and deposits will cause any spark plug to slowly erode, it should be removed and checked in accordance with the periodic maintenance and lubrication chart. In addition, the condition of the spark plug can reveal the condition of the engine. The porcelain insulator around the center electrode of the spark plug should be a medium-to-light tan (the ideal color when the vehicle is ridden normally). If

the spark plug shows a distinctly different color, the engine could be defective. Do not attempt to diagnose such problems yourself. Instead, have a Yamaha dealer check the vehicle. If the spark plug shows signs of electrode erosion and excessive carbon or other deposits, it should be replaced.

Specified spark plug:

NGK / BR8HS

EAU19620

Before installing a spark plug, the spark plug gap should be measured with a wire thickness gauge and, if necessary, adjusted to specification.

ZAUM0037

Before riding, check that the brake fluid is above the minimum level mark and replenish if necessary. A low brake fluid level may indicate worn brake pads and/or brake system leakage. If the brake fluid level is low, be sure to check the brake pads for wear and the brake system for leakage. Observe these precautions:

● When checking the fluid level,

make sure that the top of the master cylinder is level by turning the handlebars.

● Use only the recommended quality

brake fluid, otherwise the rubber seals may deteriorate, causing leakage and poor braking performance.

Recommended brake fluid:

DOT 3 or 4

● Refill with the same type of brake

fluid. Mixing fluids may result in a harmful chemical reaction and lead to poor braking performance.

● Be careful that water does not en-

ter the master cylinder when refilling. Water will significantly lower the boiling point of the fluid and may result in vapor lock.

● Brake fluid may deteriorate paint-

ed surfaces or plastic parts. Always clean up spilled fluid immediately.

● As the brake pads wear, it is nor-

mal for the brake fluid level to gradually go down. However, if the brake fluid level goes down suddenly, have a Yamaha dealer check the cause.

Troubleshooting

Although Yamaha scooters receive a thorough inspection before shipment from the factory, trouble may occur during operation. Any problem in the fuel, compression, or ignition systems, for example, can cause poor starting and loss of power. The following troubleshooting chart represents a quick and easy procedure for checking these vital systems yourself. However, should your scooter require any repair, take it to a Yamaha dealer, whose skilled technicians have the necessary tools, experience, and know-how to service the scooter properly. Use only genuine Yamaha replacement parts. Imitation parts may look like Yamaha parts, but they are often inferior, have a shorter service life and can lead to expensive repair bills.

SCOOTER CARE AND STORAGE

Care

While the open design of a scooter reveals the attractiveness of the technology, it also makes it more vulnerable. Rust and corrosion can develop even if high-quality components are used. A rusty exhaust pipe may go unnoticed on a car, however, it detracts from the overall appearance of a scooter. Frequent and proper care does not only comply with the terms of the warranty, but it will also keep your scooter looking good, extend its life and optimize its performance.

Before cleaning

1. Cover the muffler outlet with a

plastic bag after the engine has cooled down.

2. Make sure that all caps and covers as well as all electrical couplers and connectors, including the spark plug cap, are tightly installed.

3. Remove extremely stubborn dirt, like oil burnt onto the crankcase, with a degreasing agent and a brush, but never apply such prod-

EAU26090

ucts onto seals, gaskets and wheel axles. Always rinse the dirt and degreaser off with water.

Cleaning

ECA10780

CAUTION:

● 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 affected area any longer than instructed. Also, thoroughly rinse the area off with water, immediately dry it, and then apply a corrosion protection spray.

● 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.

● 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

7-1

thinner, fuel (gasoline), rust removers 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 areas: seals (of wheel and swingarm 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 windshield. Test the product on a small hidden part of the windshield to make sure that it does not leave any marks. If the windshield is scratched, use a quality plastic polishing compound after washing.

SCOOTER CARE AND STORAGE

After normal use Remove dirt with warm water, a mild detergent, and a soft, clean sponge, and then rinse thoroughly with clean water. Use a toothbrush or bottlebrush for hard-to-reach areas. Stubborn dirt and insects will come off more easily if the area is covered with a wet cloth for a few minutes before cleaning.

After riding in the rain, near the sea or on salt-sprayed roads Since sea salt or salt sprayed on the roads during winter are extremely corrosive in combination with water, carry out the following steps after each ride in the rain, near the sea or on saltsprayed roads.

NOTE:

Salt sprayed on roads in the winter may remain well into spring.

1. Clean the scooter with cold water and a mild detergent after the engine has cooled down.

ECA10790

CAUTION:

Do not use warm water since it increases the corrosive action of the salt.

2. Apply a corrosion protection spray on all metal, including chrome- and nickel-plated, surfaces to prevent corrosion.

After cleaning

1. Dry the scooter with a chamois or an absorbing cloth.

2. Use a chrome polish to shine chrome, aluminum and stainlesssteel parts, including the exhaust system. (Even the thermally induced discoloring of stainlesssteel exhaust systems can be removed through polishing.)

3. To prevent corrosion, it is recommended to apply a corrosion protection spray on all metal, including chrome- and nickel-plated, surfaces.

4. Use spray oil as a universal cleaner to remove any remaining dirt.

5. Touch up minor paint damage caused by stones, etc.

6. Wax all painted surfaces.

7. Let the scooter dry completely before storing or covering it.

EWA10940

WARNING

● Make sure that there is no oil or

wax on the brakes or tires. If necessary, clean the brake discs and brake linings with a regular brake disc cleaner or acetone, and wash the tires with warm water and a mild detergent.

● Before operating the scooter

test its braking performance and cornering behavior.

ECA10800

CAUTION:

● Apply spray oil and wax spar-

ingly and make sure to wipe off any excess.

● Never apply oil or wax to any

rubber and plastic parts, but treat them with a suitable care product.

SCOOTER CARE AND STORAGE

● Avoid using abrasive polishing

compounds as they will wear away the paint.

NOTE:

Consult a Yamaha dealer for advice on what products to use.

EAU26300

Storage

Short-term

Always store your scooter in a cool, dry place and, if necessary, protect it against dust with a porous cover.

ECA10820

CAUTION:

● 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 chemicals are stored.

Long-term

Before storing your scooter for several months:

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

7-3

2. Drain the carburetor float chamber by loosening the drain bolt; this will prevent fuel deposits from building up. Pour the drained fuel into the fuel tank.

3. Fill up the fuel tank and add fuel stabilizer (if available) to prevent the fuel tank from rusting and the fuel from deteriorating.

4. Perform the following steps to protect 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 place the spark plug on the cylinder head so that the electrodes are grounded. (This will limit sparking during the next step.)

d. Turn the engine over several

times with the starter. (This will coat the cylinder wall with oil.)

e. Remove the spark plug cap

from the spark plug, and then install the spark plug and the spark plug cap.

SCOOTER CARE AND STORAGE

EWA10950

WARNING

To prevent damage or injury from sparking, make sure to ground the spark plug electrodes while turning the engine over.

5. Lubricate all control cables and the pivoting points of all levers and pedals as well as of the sidestand/centerstand.

6. Check and, if necessary, correct the tire air pressure, and then lift the scooter so that both of its wheels are off the ground. Alternatively, turn the wheels a little every month in order to prevent the tires from becoming degraded in one spot.

7. Cover the muffler outlet with a plastic bag to prevent moisture from entering it.

8. Remove the battery and fully charge it. Store it in a cool, dry place and charge it once a month. Do not store the battery in an excessively cold or warm place [less than 0 °C (30 °F) or

more than 30 °C (90 °F)]. For more information on storing the battery, see page 6-18.

NOTE:

Make any necessary repairs before storing the scooter.
