4VP-F8199-E1.pm65 7 2/4/2004, 4:21 PM EAU00021 Q GIVE SAFETY THE RIGHT OF WAY 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! 1-1 4VP-F8199-E1.pm65 8 2/4/2004, 4:21 PM EAU02964 FURTHER SAFE RIDING POINTS FOR THIS MODEL 1. Left turn 1. 8 Be sure to signal clearly when making turns. 8 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. 8 Slow down as you approach a corner or turn. Once you have completed a turn, accelerate slowly. 8 Be careful when passing parked cars. A driver might not see you and open a door in your path. Right turn 8 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. 8 The brake lining could get wet when you wash the scooter. After washing the scooter, check the brakes before riding. 8 Always wear a helmet, gloves, trousers (tapered around the cuff and ankle so they do not flap), and a bright colored jacket. 8 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. 1-2 4VP-F8199-E1.pm65 9 2/4/2004, 4:21 PM DESCRIPTION Left view 4 3 5 2 6 1 7 8 9 0 1. 2. 3. 4 5.

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 crankcase, 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 cC 9 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. 7-1 4VP-F8199-E1.pm65 51 2/4/2004, 4:21 PM SCOOTER CARE AND STORAGE 9 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. 9 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. 9 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 cC Do not use warm water since it increases the corrosive action of the salt. 2. Be sure to apply a corrosion protection spray on all (even chrome- and nickel-plated) metal surfaces to prevent corrosion. 7-2 4VP-F8199-E1.pm65 52 2/4/2004, 4:21 PM SCOOTER CARE AND STORAGE 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 w 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. NOTE: Consult a Yamaha dealer for advice on what products to use. ECA00013 cC 9 Apply spray oil and wax sparingly and wipe off any excess. 9 Never apply oil or wax on rubber and plastic parts, but treat them with a suitable care product. 9 Avoid using abrasive polishing compounds as they wear away the paint. 7-3 4VP-F8199-E1.pm65 53 2/4/2004, 4:21 PM 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 cC 9 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. 9 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.

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. 8. Cover up the muffler outlet with a plastic bag to prevent moisture from entering. 9. 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”. NOTE: Make any necessary repairs before storing the scooter. 7-5 4VP-F8199-E1.pm65 55 2/4/2004, 4:21 PM EAU01038 SPECIFICATIONS Specifications Model YW 100E Engine oil Type Dimensions Yamalube 2 or 2-stroke engine oil (JASO FC grade Overall length 1,890 mm Overall width 660 mm Overall height 1,115 mm Seat height 765 mm Type SAE 85 W 140 Wheel base 1,270 mm Total amount 0.13 L Ground clearance 119 mm Air filter Minimum turning radius Basic weight with oil and full 1,800 mm Fuel fuel tank 96 kg or ISO EG-C, EG-D grade) Total amount Final gear oil Engine Wet type element Type Regular unleaded gasoline Fuel tank capacity 5.7 L Carburetor Engine type Air-cooled 2-stroke Cylinder arrangement Forward-inclined single cylinder Displacement 101 cm3 Bore × Stroke 52.0 × 47.6 mm Compression ratio 6.6:1 Starting system Electric / kick starter Lubrication system Separate lubrication Type × quantity VM16SS × 1 Manufacturer Taiwan Mikuni Spark plug Type / Manufacturer BPR7HS / NGK Spark plug gap 0.9 ~ 1.0 mm Clutch type 8-1 4VP-F8199-E1.pm65 56 1.4 L 2/4/2004, 4:21 PM Dry, centrifugal automatic SPECIFICATIONS Transmission Manufacturer/model Primary reduction system Helical gear Front CHENG SHIN / 56J Primary reduction ratio 3.133 Rear CHENG SHIN / 59J Secondary reduction system Spur gear Maximum load* Secondary reduction ratio 3.308 Air pressure Transmission type V-belt automatic Operation Centrifugal automatic type 160 kg Up to 90 kg load* Chassis Front 200 kpa(2.0 kg / cm2,2.0 bar) Rear 200 kpa(2.0 kg / cm2,2.0 bar) 90 kg load ~ maximum load* Frame type Steel tube underbone Caster angle 26° Front 200 kpa(2.0 kg / cm2,2.0 bar) Trail 86 mm Rear 200 kpa(2.0 kg / cm2,2.0 bar) Tire Tubeless *Load is total weight of cargo, rider and accessories.
