Introduction

WARNING

EAU41075

Congratulations on your purchase of the Yamaha PW50 / PW50G / PW50G2. This model is the result of Yamaha’s vast experience in the production of fine sporting, touring, and pacesetting racing machines. It represents the high degree of craftsmanship and reliability that have made Yamaha a leader in these fields. This manual will give you an understanding of the operation, inspection, and basic maintenance of this motorcycle. If you have any questions concerning the operation or maintenance of your motorcycle, please consult a Yamaha dealer. The design and manufacture of this Yamaha motorcycle fully comply with the emissions standards for clean air applicable at the date of manufacture. Yamaha has met these standards without reducing the performance or economy of operation of the motorcycle. To maintain these high standards, it is important that you and your Yamaha dealer pay close attention to the recommended maintenance schedules and operating instructions contained within this manual.

Yamaha continually seeks advancements in product design and quality. There-

fore, while this manual contains the most current product information available at the time of printing, there may be minor discrepancies between your motorcycle and this manual. If there is any question concerning this manual, please consult a

Yamaha dealer.

Please read this manual carefully and completely before operating this motorcycle.

EWA10032

EWA14352

This motorcycle is designed and manufactured for off-road use only. It is il- legal to operate this motorcycle on any public street, road or highway. Such use is prohibited by law. This motorcycle complies with almost all state offhighway noise level and spark arrester laws and regulations. Please check your local riding laws and regulations before operating this motorcycle.

AN IMPORTANT SAFETY MESSAGE:

 Read this manual carefully and completely before operating this motorcycle.

Make sure you understand all instructions.

 Pay close attention to the warning and notice labels on the motorcycle.  Never operate a motorcycle without proper training or instruction.  Weight of the rider should not exceed 25 kg (55 lb).

AN IMPORTANT NOTE TO PARENTS:

This motorcycle is not a toy. Before you let your child ride this motorcycle, you

Introduction

safely. Parents should supervise their child’s use of the motorcycle at all times. Parents should permit continued use only if they determine that the child has the ability to operate the motorcycle safely. Your motorcycle is equipped with an adjustable speed limiter and a power reduction plate. Yamaha recommends that all beginners start off with the speed limiter adjusting screw turned in and the power reduction plate installed in the exhaust manifold to limit the power available while they learn. The limiter screw may be gradually turned out to increase maximum speed as the beginner becomes more familiar with operating the motorcycle. Parents should decide when to adjust the motorcycle for more power as their youngster’s riding skills improve. Once the rider can operate with skill at the top speed permitted by adjusting the speed limiter alone, the power reduction plate can be removed. Since removal of this plate will result in a significant increase in power, turn the speed limiter back in again; adjust it out in stages as you did before.

Motorcycles are single track vehicles. Their safe use and operation are de- pendent 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 motorcycle.

He or she should:

 Obtain thorough instructions from a competent source on all aspects of mo-

torcycle operation.

 Observe the warnings and maintenance requirements in this Owner’s Manu-

al.

 Obtain qualified training in safe and proper riding techniques.  Obtain professional technical service as indicated in this Owner’s Manual

and/or when made necessary by mechanical conditions.

Safety information

Be a Responsible Owner

As the vehicle’s owner, you are responsible for the safe and proper operation of your motorcycle.

Motorcycles 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 motorcycle. He or she should:

 Obtain thorough instructions from

a competent source on all aspects of motorcycle operation.

 Observe the warnings and mainte-

nance requirements in this Owner’s Manual.

 Obtain qualified training in safe

and proper riding techniques.

 Obtain professional technical ser-

vice as indicated in this Owner’s Manual and/or when made necessary by mechanical conditions.

 Never operate a motorcycle with-

out proper training or instruction. Take a training course. Beginners should receive training from a certified instructor. Contact an authorized motorcycle dealer to find out about the training courses nearest you.

Safe Riding

Perform the pre-operation checks each time you use the vehicle to make sure it is in safe operating condition. Failure to inspect or maintain the vehicle properly increases the possibility of

EAU4093C

an accident or equipment damage. See page 5-1 for a list of pre-operation checks.

 This motorcycle is designed for

off-road use only, therefore, it is illegal to operate it on public streets, roads, or highways, even a dirt or gravel one. Off-road use on public lands may be illegal. Please check local regulations before riding.

 This motorcycle is designed to

carry the operator only. No passengers.

 The failure of motorists to detect

and recognize motorcycles in traffic is the predominating cause of automobile/motorcycle accidents. Many accidents have been caused by an automobile driver who did not see the motorcycle. 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 you are approaching and passing through intersections, since intersections are the most likely places for motorcycle accidents to occur.

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

• Never maintain a motorcycle without proper knowledge. Contact an authorized motorcycle dealer to inform you on ba-

2-1

Safety information

sic motorcycle maintenance. Certain maintenance can only be carried out by certified staff.

 Many accidents involve inexperi-

enced operators.

• Make sure that you are qualified and that you only lend your motorcycle 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 motorcycle until you have become thoroughly familiar with the motorcycle and all of its controls.

 Many accidents have been

caused by error of the motorcycle 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). Never travel faster than warranted by conditions.

 Ride cautiously in unfamiliar ar-

eas. You may encounter hidden obstacles that could cause an accident.

 The posture of the operator is im-

portant for proper control. The operator should keep both hands on the handlebar and both feet on the operator footrests during operation to maintain control of the motorcycle.

 Never ride under the influence of

alcohol or other drugs.

Protective Apparel

The majority of fatalities from motorcycle 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 that could delay seeing a hazard.

 The use of a jacket, heavy boots,

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, footrests, or wheels and cause injury or an accident.

 Always wear protective clothing

that covers your legs, ankles, and feet. The engine or exhaust system become very hot during or after operation and can cause burns.

Avoid Carbon Monoxide Poisoning

All engine exhaust contains carbon monoxide, a deadly gas. Breathing carbon monoxide can cause headaches, dizziness, drowsiness, nausea, confusion, and eventually death. Carbon Monoxide is a colorless, odorless, tasteless gas which may be present even if you do not see or smell any engine exhaust. Deadly levels of carbon monoxide can collect rapidly and you can quickly be overcome and unable to save yourself. Also, deadly levels of carbon monoxide can linger for hours or days in enclosed or poorly

2-2

Safety information

ventilated areas. If you experience any symptoms of carbon monoxide poisoning, leave the area immediately, get fresh air, and SEEK MEDICAL TREATMENT.

 Do not run engine indoors. Even if

you try to ventilate engine exhaust with fans or open windows and doors, carbon monoxide can rapidly reach dangerous levels.

 Do not run engine in poorly venti-

lated or partially enclosed areas such as barns, garages, or carports.

 Do not run engine outdoors where

engine exhaust can be drawn into a building through openings such as windows and doors.

Adding accessories to your motorcycle can adversely affect stability and handling if the weight distribution of the motorcycle is changed. To avoid the possibility of an accident, use extreme caution when adding accessories to your motorcycle. Use extra care when riding a motorcycle that has added accessories. Here are some general guidelines to follow if adding accessories to your motorcycle:

Operation of an overloaded vehicle could cause an accident.

 The weight of the operator must

not exceed 25 kg (55 lb).

 Accessory weight should be kept

as low and close to the motorcycle as possible. Securely pack your heaviest items as close to the center of the vehicle as possible and make sure to distribute the

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

 Shifting weights can create a sud-

den imbalance. Make sure that accessories are securely attached to the motorcycle before riding. Check accessory mounts frequently.

• Properly adjust the suspension for your load (suspension-adjustable models only), and check the condition and pressure of your tires.

• Never attach any large or heavy items to the handlebar, front fork, or front fender.

Genuine Yamaha Accessories

Choosing accessories for your vehicle is an important decision. Genuine Yamaha accessories, which are available only from a Yamaha dealer, have been designed, tested, and approved by Yamaha for use on your vehicle. Many companies with no connection to Yamaha manufacture parts and accessories or offer other modifications for Yamaha vehicles. Yamaha is not in a position to test the products that these aftermarket companies produce. Therefore, Yamaha can neither endorse nor recommend the use of accessories not sold by Yamaha or modifications not specifically recommended by Yamaha, even if sold and installed by a Yamaha dealer.

2-3

Safety information

Aftermarket Parts, Accessories, and Modifications

While you may find aftermarket products similar in design and quality to genuine Yamaha accessories, recognize that some aftermarket accessories or modifications are not suitable because of potential safety hazards to you or others. Installing aftermarket products or having other modifications performed to your vehicle that change any of the vehicle’s design or operation characteristics can put you and others at greater risk of serious injury or death. You are responsible for injuries related to changes in the vehicle. Keep the following guidelines in mind, as well as those provided under “Loading” when mounting accessories.

 Never install accessories that

would impair the performance of your motorcycle. 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.

• Accessories fitted to the handlebar or the front fork area can create instability due to improper weight distribution. 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 motorcycle. Wind may at-

tempt to lift the motorcycle, or the motorcycle may become unstable in cross winds.

• 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 motorcycle’s electrical system, an electric failure could result, which could cause a dangerous loss of lights or engine power.

Aftermarket Tires and Rims

The tires and rims that came with your motorcycle were designed to match the performance capabilities and to provide the best combination of handling, braking, and comfort. Other tires, rims, sizes, and combinations may not be appropriate. Refer to page 7-14 for tire specifications and more information on replacing your tires.

Transporting the Motorcycle

Be sure to observe following instructions before transporting the motorcycle in another vehicle.

 Remove all loose items from the

motorcycle.

 Check that the fuel cock is in the

“S” (stop) position and that there are no fuel leaks.

2-4

Safety information

 Point the front wheel straight

ahead on the trailer or in the truck bed, and choke it in a rail to prevent movement.

 Shift the transmission in gear (for

models with a manual transmis-

sion).

 Secure the motorcycle with tie-

downs or suitable straps that are attached to solid parts of the motorcycle, such as the frame or upper front fork triple clamp (and not, for example, to rubber-mounted handlebars or turn signals, or parts that could break). Choose the location for the straps carefully so the straps will not rub against painted surfaces during transport.

 The suspension should be com-

pressed somewhat by the tiedowns, if possible, so that the motorcycle will not bounce excessively during transport.

Engine break-in

There is never a more important period in the life of your engine than the first 5 hours of riding. It is also important to accustom the rider to the motorcycle during this time. Please read the following information carefully. Since the engine is brand new, do not put an excessive load on it for the first 5 hours of operation. 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 that might result in engine overheating must be avoided. However, momentary full-throttle operation under load (i.e., two to three seconds maximum) does not harm the engine. Each fullthrottle acceleration should be followed with a substantial rest period for the engine. To allow the engine to cool down from the temporary buildup of heat, cruise at a lower engine speed. After the first 5 hours of operation, thoroughly check the motorcycle for loose parts, oil leakage and any other problems. Be sure to inspect and make adjustments thoroughly, especially cables. In addition, check all fittings and fasteners for looseness, and tighten if necessary.

Troubleshooting

Although Yamaha motorcycles 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 motorcycle require any repair, take it to a Yamaha dealer, whose skilled technicians have the necessary tools, experience, and know-how to service the motorcycle 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.

EWA15142

When checking the fuel system, do not smoke, and make sure there are no open flames or sparks in the area, including pilot lights from water heaters or furnaces. Gasoline or gasoline vapors can ignite or explode, causing severe injury or property damage.

Matte color caution

ECA15193

Some models are equipped with matte colored finished parts. Be

sure to consult a Yamaha dealer for advice on what products to use before 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 finished parts.

EAU40636

Care

While the open design of a motorcycle 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 motorcycle. Frequent and proper care does not only comply with the terms of the warranty, but it will also keep your motorcycle 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 products onto seals, gaskets and wheel axles. Always rinse the dirt and degreaser off with water.

Cleaning

ECA17111

 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 in-

Motorcycle care and storage

WARNING

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, etc.) and the mufflers. Use only a soft, clean cloth or sponge with water to clean plastic. However, if the plastic parts cannot be thoroughly cleaned with water, diluted mild detergent with water may be used. Be sure to rinse 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 removers or inhibitors, brake fluid, antifreeze or electrolyte.

 Do not use hi

essure wash-

gh-pr ers or steam-jet cleaners since they cause water seepage and deterioration in the following areas: seals (of wheel and swing- arm bearings, fork and brakes), electric components (couplers, connectors, and switches), breather hoses and vents.

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 or near the sea Since sea salt is extremely corrosive, carry out the following steps after each ride in the rain or near the sea.

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

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

[ECA10792]

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

After cleaning

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

2. Use a chrome polish to shine chrome, aluminum and stainlesssteel parts.

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 motorcycle dry completely before storing or covering it.

NOTICE

 Make sure that there is no oil or

wax on the tires.

 If necessary, wash the tires with

warm water and a mild deter- gent. Before riding at higher speeds, test the motorcycle’s braking performance and cornering behavior.

ECA10801

 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.

 Avoid using abrasive polishing

compounds as they will wear away the paint.

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

Storage

Short-term

Always store your motorcycle in a cool, dry place and, if necessary, protect it against dust with a porous cover. Be sure the engine and the exhaust system are cool before covering the motorcycle.

ECA10811

 Storing the motorcycle in a

poorly ventilated room or covering it with a tarp, while it is still wet, will allow water and humid- ity 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 motorcycle for several months:

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

2. For motorcycles equipped with a fuel cock that has an “S” (stop) position: Turn the fuel cock lever to “S”.

3. 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.

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

8-3

Motorcycle care and storage

TIP

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 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. WARNING! To

prevent damage or injury from sparking, make sure to ground the spark plug elec-

trodes while turning the engine over.

[EWA10952]

6. Lubricate all control cables and the pivoting points of all levers as well as of the centerstand.

7. Check and, if necessary, correct the tire air pressure, and then lift the motorcycle 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 the muffler outlet with a plastic bag to prevent moisture from entering it.

Make any necessary repairs before storing the motorcycle.

The figures quoted are emission levels and are not necessarily safe working levels. Whilst there is a correlation between the emission and exposure levels, this cannot be used reliably to determine whether or not further precautions are required. Factors that influence the actual level of exposure of work-force include the characteristics of the work room, the other sources of noise, etc. i.e. the number of machines and other adjacent processes, and the length of time for which an operator is exposed to the noise. Also the permissible exposure level can vary from country. This information, however, will enable the user of the machine to make a better evaluation of the hazard and risk.
