GIVE SAFETY THE RIGHT OF WAY

EAU00021

Scooters are fascinating vehicles, which can give you an unsurpassed feeling of power and freedom. However, they also impose certain limits, which you must accept; even the best scooter does not ignore the laws of physics.

Regular care and maintenance are essential for preserving your scooter's value and operating condition. Moreover, what is true for the scooter is also true for the rider: good performance depends on being in good shape. Riding under the influence of medication, drugs and alcohol is, of course, out of the question. Scooter riders - more than car drivers - must always be at their mental and physical best. Under the influence of even small amounts of alcohol, there is a tendency to take dangerous risks.

Protective clothing is as essential for the scooter rider as seat belts are for car drivers and passengers. Always wear a complete motorcycle suit (whether made of leather or tear-resistant synthetic materials with protectors), sturdy boots, motorcycle gloves and a properly fitting helmet. Optimum protective wear, however, should not encourage carelessness. Though full-coverage helmets and suits, in particular, create an illusion of total safety and protection, motorcyclists will always be vulnerable. Riders who lack critical self-control run the risk of going too fast and are apt to take chances. This is even more dangerous in wet weather. The good motorcyclist rides safely, predictably and defensively - avoiding all dangers, including those caused by others.

Enjoy your ride!

1. Left turn 1. Right turn

Illustration of a person riding a scooter with motion blur effect, no text or symbols present

• 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 corner 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.

• Street car rails, iron plates on road construction sites, and man-hole covers become extremely slippery when wet. Slow down and cross them with caution. Keep the scooter upright. It could slide out from under you.

• The brake lining could get wet when you wash the scooter. After washing the scooter, check the brakes before riding.
• 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.

Use a strong cord to secure any luggage to the luggage rack. A loose load will affect the stability of the scooter and could divert your attention from the road.

WARNING

If improper operation is noted, consult a Yamaha dealer immediately.

Owners are personally responsible for their vehicle's condition. Your scooter's vital functions can start to deteriorate 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 important that, in addition to a thorough visual inspection, you check the following points before each ride.

ITEM CHECKS		PAGE
Front brake	Check operation, free play, fluid level and vehicle for fluid leakage.Fill with DOT 4 (or DOT 3) brake fluid if necessary.	3-4,6-14~6-16
Rear brake	Check operation, free play.	3-4,6-14~6-15
Throttle grip and housing	Check for smooth operation.Lubricate.Adjust throttle cable free play if necessary.	6-11,6-17
Engine oil	Check oil level.Fill with oil if necessary.	3-6
Final gear oil	Check vehicle for leakage.	6-9
Wheels and tires	Check tire pressure, wear, damage.	6-12~6-14
Brake levers pivots	Check for smooth operation.Lubricate if necessary.	6-17
Chassis fasteners	Make sure that all nuts, bolts, and screws are properly tightened.Tighten if necessary.	-
Fuel tank	Check fuel level.Fill with fuel if necessary.	3-4~3-5
Lights, signals and switches	Check for proper operation.	3-3

Pre-operation checks should be made each time the scooter 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 is not working properly, have it inspected and repaired before operating the scooter.

OPERATION AND IMPORTANT RIDING POINTS

EAU00372

EAU01118

EW000129

WARNING

• Before riding this scooter, become thoroughly familiar with all operating controls and their functions. Consult a Yamaha dealer regarding any control or function that you do not thoroughly understand.
• Never start your engine or let it run for any length of time in a closed area. The exhaust fumes are poisonous and can cause loss of consciousness and death within a short time. Always operate your scooter in an area with adequate ventilation.
• For safety, be sure to start the engine with the centerstand down.

EAU02960

Starting up a cold engine

1. Turn the main switch to “*”. If the oil level indicator light comes on, turn the main switch to “ON”.

EC000045

CAUTION:

If the oil level indicator light does not come on, ask a Yamaha dealer to inspect it.

1. Completely close the throttle grip.
2. Start the engine by pushing the start switch while applying the front or rear brake or by kicking the kick starter.

NOTE:

If the engine fails to start when using the electric starter, release the start switch, wait a few seconds, then try again. Each attempt should be as short as possible to preserve the battery. Do not crank the engine more than 5 seconds on any one at-

tempt. If the engine does not start with the starter motor, kick the kick starter to start the engine.

NOTE:

For maximum engine life, always warm up the engine about 1 \~ 3 minutes before riding your scooter. Never accelerate hard with a cold engine.

EC000046

CAUTION:

See the "Engine break-in" section prior to operating the motorcycle for the first time.

OPERATION AND IMPORTANT RIDING POINTS

EAU00433

Starting off

After warming up the engine:

1. Apply the rear brake lever with your left hand and hold the grab bar with you right hand. Then push the scooter off the centerstand.
2. Sit astride the seat and adjust the rear view mirrors.
3. Check the oncoming traffic and use a turn signal.
4. Turn the throttle grip on the right handlebar slowly and you will start off. Remember to turn off the turn signal.

EAU00434

Acceleration

The speed can be adjusted by opening and closing the throttle grip. Turning it toward you increases the speed, and turning it in the opposite direction decreases the speed.

Braking

1. Close the throttle grip.
2. Apply both front and rear brakes simultaneously with light pressure and increase the pressure slowly.

EAU00435

EW000057

WARNING

• Avoid hard or sudden braking. It may cause the scooter to skid or overturn.
• Be sure to apply the brake carefully if leaning over to one side. Improper braking could lead to a skid.
• Street car rails, metal plates on road construction sites, and man-hole covers become particularly slippery when they get wet. Cross them slowly and cautiously.
• Braking on a wet road is very difficult.
• Braking on a hill can be difficult. Proceed slowly when riding downhill.

EAU00436

Engine break-in

There is never a more important period in the life of your scooter than the period between zero and 1,000 km (600 mi). For this reason we ask that you carefully read the following material. Because the engine is brand new, you must not put an excessive load on it for the first 1,000 km (600 mi). The various parts in the engine wear and polish themselves to the correct operating clearances. During this period, prolonged full throttle operation, or any condition which might result in excessive heating of the engine, must be avoided.

OPERATION AND IMPORTANT RIDING POINTS

EAUT0003

0 \~ 150 km (0 \~ 100 mi)

Avoid operation above 1/3 throttle. Stop the engine and let it cool for 5 to 10 minutes after every hour of operation. Vary the speed of the scooter from time to time. Do not operate it at one set throttle position.

150 \~ 500 km (100 \~ 300 mi)

Avoid prolonged operation above 1/2 throttle.

500 \~ 1,000 km (300 \~ 600 mi)

Avoid cruising speeds in excess of 3/4 throttle.

ECT00060

CAUTION:

After 1,000 km of operation, be sure to replace the final gear oil.

1,000 km (600 mi) and beyond

Avoid prolonged full throttle operation. Vary speeds occasionally.

EC000049

CAUTION:

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

EAU00460

Parking

When parking the scooter, stop the engine and remove the ignition key.

EW000058

WARNING

The exhaust system is hot. Park the scooter in a place where pedestrians or children are not likely to touch the scooter.

PERIODIC MAINTENANCE AND MINOR REPAIR

The ideal color on the white insulator a round the center electrode is a medium-to-light tan color for a scooter that is being ridden normally.

Do not attempt to diagnose such problems yourself. Instead, take the scooter to a Yamaha dealer. You should periodically remove and inspect the spark plug because heat and deposits will cause any spark plug to slowly break down and erode. If electrode erosion becomes excessive, or if carbon and other deposits are excessive, you should replace the spark plug.

Specified spark plug: BPR7HS (NGK)

Inspecting the brake fluid level

Insufficient brake fluid may let air enter the brake system, possibly causing the brakes to become ineffective.

Before riding, check that the brake fluid is above the minimum level and fill when necessary.

Observe these precautions:

• When checking the fluid level, make sure the top of the master cylinder is level by turning the handlebars.
• Use only the designated quality brake fluid. Otherwise, the rubber seals may deteriorate, caus-

ing leakage and poor brake performance.

Recommended brake fluid: DOT 4

NOTE:

If DOT 4 is not available, DOT 3 can be used.

• Refill with the same type of brake fluid. Mixing fluids may result in a harmful chemical reaction and lead to poor brake performance.
• Be careful that water does not enter 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 painted surfaces or plastic parts. Always clean up spilled fluid immediately.
• Have a Yamaha dealer check the cause if the brake fluid level goes down.

Troubleshooting

Although Yamaha scooters receive a rigid inspection before shipment from the factory, trouble may occur during operation.

Any problem in the fuel, compression, or ignition systems can cause poor starting and loss of power. The troubleshooting chart describes a quick, easy procedure for making checks.

If your scooter requires any repair, bring it to a Yamaha dealer. The skilled technicians at a Yamaha dealership have the tools, experience, and know-how to properly service your motorcycle. Use only genuine Yamaha parts on your scooter. Imitation parts may look like Yamaha parts, but they are often inferior. Consequently, they have a shorter service life and can lead to expensive repair bills.

SCOOTER CARE AND STORAGE

EAU01522

Care

The exposure of its technology makes a scooter charming but also vulnerable. Although high-quality components are used, they are not all rust-resistant. While a rusty exhaust pipe may remain unnoticed on a car, it does look unattractive on a scooter. Frequent and proper care, however, will keep your scooter looking good, extend its life and maintain its performance. Moreover, the warranty states that the vehicle must be properly taken care of. For all these reasons, it is recommended that you observe the following cleaning and storing precautions.

Before cleaning

1. Cover up the muffler outlet with a plastic bag.
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 crank-case, with a degreasing agent and a brush, but never apply such products onto seals, gaskets and wheel axles. Always rinse the dirt and degreaser off with water.

Cleaning

After normal use

Remove dirt with warm water, a neutral detergent and a soft clean sponge, then rinse with plenty of clean water. Use a tooth and bottle brush for hard-to-reach parts.

Tougher dirt and insects will come off more easily if the area is covered with a wet cloth for a few minutes before cleaning.

ECA00011

CAUTION:

- Avoid using strong acidic wheel cleaners. 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.

SCOOTER CARE AND STORAGE

• 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 thinner, fuel (gasoline), rust removers or inhibitors, brake fluid, antifreeze or electrolyte.
• Do not use high-pressure washers or steam-jet cleaners since they cause water seepage and deterioration in the following areas: seals (of wheel bearings, swingarm bearings, bearings, forks and brakes), electric components (couplers, connectors, instruments, switches and lights), breather hoses and vents.

9 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 they do not leave any marks. If the windshield is scratched, use a quality plastic polishing compound after washing.

After riding in the rain, near the sea or on salt-sprayed roads

Since sea salt or salt sprayed on the roads in the winter are extremely corrosive in combination with water, carry out the following steps after each ride in the rain, near the sea or on salt-sprayed roads. (Salt sprayed in the winter may remain on the roads well into spring.)

1. Clean your scooter with cold water and soap after the engine has cooled down.

ECA00012

CAUTION:

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

1. Be sure to apply a corrosion protection spray on all (even chrome- and nickel-plated) metal 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 stainless-steel parts, including the exhaust system. (Even the thermally induced discoloring of stainless-steel exhaust systems can be removed through polishing.)
3. To prevent corrosion, it is recommended to apply a corrosion protection spray on all (even chrome- and nickel-plated) metal 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 it or covering it.

EWA00002

WARNING

Make sure that there is no oil or wax on the brakes and tires. If necessary, 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 scooter for its braking performance and cornering behavior.

ECA00013

CAUTION:

• Apply spray oil and wax sparingly and wipe off any excess.
• Never apply oil or wax on rubber and plastic parts, but treat them with a suitable care product.
• Avoid using abrasive polishing compounds as they wear away the paint.

NOTE:

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

SCOOTER CARE AND STORAGE

Storage

Short-term

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

ECA00015

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.
2. Drain the carburetor float chambers by loosening the drain bolts; this will prevent fuel deposits from building up. Pour the drained fuel into the fuel tank.
3. Only for scooters equipped with a fuel cock which has an "OFF" position: Turn the fuel cock to "OFF".
4. Fill up the fuel tank and add fuel stabilizer (if available) to prevent the fuel tank from rusting and the fuel from deteriorating.
5. 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 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, install the spark plug and then the spark plug cap.

EWA00003

WARNING

When turning the engine over, be sure to ground the spark plug electrodes to prevent damage or injury from sparking.

1. Lubricate all control cables and the pivoting points of all levers and pedals as well as of the sidestand/centerstand.
2. Check and, if necessary, correct the tire air pressure, then raise 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.
3. Cover up the muffler outlet with a plastic bag to prevent moisture from entering.
4. Remove the battery and fully charge it. Store it in a cool, dry place and recharge it once a month. Do not store the battery in an excessively cold or warm place (less than 0°C or more than 30°C). For more information, see "Battery storage" in the chapter "PERIODIC MAINTENANCE AND MINOR REPAIRS".
