YAMAHA MOTOR CORPORATION, U.S.A. SNOWMOBILE LIMITED WARRANTY

Yamaha Motor Corporation, U.S.A. hereby warrants that new Yamaha snowmobiles purchased from an autho- rized Yamaha snowmobile dealer in the continental United States will be free from defects in material and workmanship for the period of time stated herein, subject to certain stated limitations.

WARRANTY PERIOD: 1. All Yamaha snowmobiles shall be warranted for a

term of one (1) year from the date of purchase, plus a special early-season extension (if applicable).

2. All Yamaha snowmobile clutch components are war- ranted against abnormal wear for one (1) year from the date of purchase, plus a special early-season extension (if applicable).

DURING THE PERIOD OF WARRANTY any au- thorized Yamaha snowmobile dealer will, free of charge, repair or replace, at Yamahas option, any part adjudged defective by Yamaha due to faulty workmanship or material from the factory. Parts used in warranty repairs will be warranted for the balance of the snowmobiles warranty period. All parts replaced under warranty be- come the property of Yamaha Motor Corporation, U.S.A.

GENERAL EXCLUSIONS from this warranty shall include any failures to the machine caused by: 1. Competition, racing, or non-Yamaha authorized

rental use. 2. Operation on surfaces other than snow or ice. 3. Installation of parts or accessories that are not quali-

tatively equivalent to genuine Yamaha parts. 4. Abnormal strain, neglect, or abuse. 5. Lack of proper maintenance. 6. Accident or collision damage. 7. Modification to original parts.

SPECIFIC EXCLUSIONS from this warranty shall include parts replaced due to normal wear or routine maintenance including oil, spark plugs, clutch drive belts, slide runners, and track.

THE CUSTOMERS RESPONSIBILITY under this warranty shall be to: 1. Operate and maintain the snowmobile as specified in

the appropriate Owners Manual. 2. Give notice to an authorized

Yamaha snowmobile dealer of any and all apparent defects within ten (10) days after discovery, and make the machine available at that time for inspection and repairs at such dealers place of business. You may locate your nearest authorized Yamaha dealer through your local telephone directory.

WARRANTY TRANSFER: To transfer any remain- ing warranty from the original purchaser to any subse- quent purchaser, it is imperative that the machine be inspected and registered for warranty by an authorized Yamaha snowmobile dealer. In order for this warranty to remain in effect, this inspection and registration must take place within ten (10) days after ownership transfer. An inspection and registration fee will be charged for this service.

WARRANTY QUESTIONS AND ANSWERS

Q. What costs are my responsibility during the warranty period?

A. The customers responsibility includes all costs of normal maintenance services, non-warranty repairs, accident and collision damages, as well as oil, spark plugs, clutch drive belts, and slide runners.

Q. What are some examples of abnormal strain, ne- glect, or abuse?

A. These terms are general and overlap each other in areas. Specific examples include: Running the ma- chine out of oil, hitting an object submerged under snow, operation on surfaces other than snow or ice, operating the machine with a broken or damaged part which causes another part to fail, and so on. If you have any specific questions on operation or maintenence, please contact your dealer for advice.

Q. May I perform any or all of the recommended main- tenance shown in the Owners Manual instead of having the dealer do them?

A. Yes, if you are a qualified snowmobile mechanic and follow the procedures specified in the Owners and Service Manual. We do recommend, however, that items requiring special tools or equipment be done by a Yamaha snowmobile dealer.

Q. Under what conditions is the clutch not covered by warranty?

A. Clutches as well as clutch components wear with use. Normal wear is not covered under warranty such service is the customers responsibility. Abnormal wear is, however, covered for one (1) year from the date of purchase. Your Yamaha snowmobile dealer possesses criteria as to what constitutes abnormal wear.

Q. Will the warranty be void or cancelled if I do not operate or maintain my new Yamaha exactly as specified in the Owners Manual?

A. No. The warranty on a new Yamaha cannot be voided or cancelled. However, if a particular fail- ure is caused by operation or maintenance other than as shown in the Owners Manual, that failure may not be covered under warranty.

Q. What responsibility does my dealer have under this warranty?

A. Each Yamaha snowmobile dealer is expected to: 1. Completely set up every new machine before sale. 2. Explain the operation, maintenance, and warranty

requirements to your satisfaction at the time of sale, and upon your request at any later date.

3. In addition, each Yamaha snowmobile dealer is held responsible for his setup, service and warranty repair work.

Q. Whom should I contact if I have further questions about this warranty?

A. Your Yamaha snowmobile dealer has the informa- tion and experience necessary to answer almost any questions about this warranty. If the dealer is not able to do so, he is expected to contact Yamaha Motor Corporation, U.S.A., for clarification or assistance.

YAMAHA EXTENDED SERVICE (Y.E.S.)

Keep your Yamaha protected even after your warranty expires with genuine Yamaha Ex- tended Service (Y.E.S.).

Y.E.S. is designed and administered by Yamaha Motor Corporation to provide maximum owner satisfaction. You get un- interrupted factory-backed coverage for extra peace of mind.

Y.E.S. is flexible. You choose the plan thats right for you: 12 months, 24 months, or 36 months beyond your warranty period.

Y.E.S. is designed and administered by the same Yamaha people who handle your warranty and it shows in the compr- ehensive coverage benefits. There are no mileage limitations. Coverage isnt limited to moving parts or the drive train like many other plans. And Y.E.S. covers manu- facturing defects just like the warranty. See the sample contract at your Yamaha dealer to see how comforting uninterrupted fac- tory-backed protection can be.

You dont have to pay anything for covered repairs. Theres no deductible to pay, and repairs arent pro-rated. You dont have any out-of pocket expenses for covered re- pairs.

In addition, Travel and Recreation Inter- ruption Protection (TRIP) is included at no extra cost. TRIP gives you up to $150 reim- bursement per occurrence for any reason- able expenses you incur because your Yamaha needs covered service: replace- ment vehicle rental, emergency towing , phone calls, even food and lodging when you are away from home. This superb coverage goes into effect when you pur- chase Y.E.S., so it applies to any warranty repairs as well as covered repairs during your entire Y.E.S. plan period.

Y.E.S. coverage is honored at any author- ized Yamaha dealer nationwide.

Y.E.S. coverage is transferrable to a new owner if you sell or trade-in. That can make your Yamaha much more valuable!

This excellent Y.E.S. plan coverage is only available to Yamaha owners like you, and only while your Yamaha is still within the Yamaha Limited Warranty period.

You can also save money: Y.E.S. costs less within the first 90 days after you buy your Yamaha. See your dealer today!

A special note:

If visiting your dealer isnt convenient, contact Yamaha with your Primary ID number (your engine number). Well be happy to help you get the Y.E.S. coverage you need.

SAFETY INFORMATION When you ride your snowmobile, you must know and use the following for your safety. Severe injury or death may result if you ignore any of the following.

Before Operating 1. Read the Owners Manual and all labels before operat-

ing this machine. Become familiar with all of the oper- ating controls and their function. Consult a Yamaha dealer about any control or function you do not under- stand.

2. This machine was not manufactured for use on public streets, roads, or highways. Such use is prohibited by law, and you could collide with another vehicle.

3. BR250T and CS340E are designed to carry the OP- ERATOR ONLY. Passengers are prohibited. Carrying a passenger can cause loss of control.

4. Do not operate the machine after drinking alcohol or taking drugs. Your ability to operate the machine is reduced by the influence of alcohol or drugs.

5. For safety and proper care of the machine, always perform the pre-operation checks on page 6-1 ~ 6-8 before starting the engine. Check the throttle, steering and brake operation every time before starting the engine. Be sure the throttle lever moves freely and it returns to the idle position when it is released.

6. Apply the parking brake before starting the engine. Never drive the machine with the parking brake ap- plied. This may overheat the brake disc and reduce braking ability.

7. Do not allow anyone to stand behind the machine when starting, inspecting or adjusting the machine. A broken track, track fittings or debris thrown by the track could be dangerous to the operator or bystanders.

8. Handle fuel with care; it is highly flammable. Never add fuel when the engine is running or hot.

Allow the engine to cool for several minutes after running.

Use an approved fuel container. Fill the fuel tank outdoors with extreme care. Never

remove the fuel cap indoors. Never fill the fuel tank indoors.

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

Make sure the fuel tank cap is closed securely after refueling. Wipe up any spilled fuel immediately.

9. If you swallow some gasoline, inhale a lot of gasoline vapor, or get some gasoline into your eye(s), see your doctor immediately. If any gasoline spills on your skin or clothing, immediately wash your skin with soap and water, and change your clothes.

10. Wear protective clothing. Wear an approved helmet, and a face shield or goggles. Also, wear a good quality snowmobile suit, boots, and a pair of snowmobile gloves or mittens that will permit use of your thumbs and fingers for operation of the controls.

Operation 1. Do not run the engine indoors, except when starting the

engine to transport the machine in or out of the building. Open the outside doors; exhaust fumes are dangerous.

2. Be careful where you ride. There may be obstacles hidden beneath the snow. Stay on established trails to minimize your exposure to hazards. Ride slowly and cautiously when you ride off of established trails. Hitting a rock or stump, or running into wires could cause an accident and injury.

3. This machine is not designed for use on surfaces other than snow or ice. Use on dirt, sand, grass, rocks, or bare pavement may cause loss of control and may damage the machine.

4. Avoid operating on glare ice, or on snow which has a lot of dirt or sand mixed in. Operation under such condi- tions will damage or result in rapid wear of ski runners, drive track, slide runners and drive sprockets.

5. Always have other snowmobilers with you when going on a ride. You may need help if you run out of fuel, have an accident, or damage your snowmobile.

6. Many surfaces such as ice and hard-packed snow require much longer stopping distances. Be alert, plan ahead and begin decelerating early. The best braking method on most surfaces is to release the throttle and apply the brake gently not suddenly.

Maintenance and Storage 1. Modifications made to the machine not approved by

Yamaha, or the removal of original equipment may render your machine unsafe for use and may cause severe personal injury. Modifications may also make your machine illegal to use.

2. Never store the machine with fuel in the fuel tank inside a building where ignition sources are present such as hot water and space heaters, open flame, spark, clothes dryers, and the like. Allow the engine to cool before storing in any enclosure.

3. Always refer to STORAGE for important details if the machine is to be stored for an extended period.

4. Maintain or replace safety and instruction labels, as necessary.

RIDING YOUR SNOWMOBILE

GETTING TO KNOW YOUR SNOWMOBILE A snowmobile is a rider active vehicle, and your riding position and your balance are the two basic factors of maneuvering your snowmobile. Riding your snowmobile requires skills acquired through practice over a period of time. Take the time to learn the basic techniques well before attempting more difficult maneuvers. Riding your new snowmobile can be a very enjoyable activity, providing you with hours of pleasure. But it is essential to familiarize yourself with the operation of the snowmobile to achieve the skill necessary to enjoy riding safely. Before you begin to ride, be sure you have read this Owners Manual completely and understand the operation of the controls. Pay particular attention to the safety information on page 3-1 ~ 3-3. Please read all warning and caution labels on your snow- mobile. Also read the Snowmobilers Safety Handbook originally supplied with your machine.

LEARNING TO RIDE YOUR SNOWMOBILE Before you ride, always perform the pre-operation checks listed on page 8-1 ~ 8-3. The short time spent checking the condition of the machine will be rewarded with added safety and a more reliable snowmobile. Always wear the proper clothing for both warmth and to help protect you from injury if an accident occurs.

Become familiar with this snowmobile at slow speeds, even if you are an experienced operator. Do not attempt to operate at maximum performance until you are totally familiar with the machines handling and performance characteristics.

The beginning operator should select a large, flat area to become familiar with the snowmobile. Make sure that this area is free of obstacles and other traffic. You should practice control of the throttle and brake, and master turning techniques in this area before trying more difficult terrain.

7-6

Set the parking brake and follow the instructions on page 7-1 ~ 7-2 to start the engine. Once it has warmed up, you are ready to begin riding your Snowmobile.

TO START OUT AND ACCELERATE 1. With the engine idling, release the parking brake. 2. Apply the throttle slowly and smoothly. The centrifugal

clutch will engage and you will start to accelerate.

WARNING

The operator should always keep both hands on the handlebars. Never put your feet outside the running boards. Avoid higher speeds until you have become thoroughly familiar with your Snowmobile and all of its controls.

BRAKING When slowing down or stopping, release the throttle and apply the brake gently-not suddenly.

WARNING

Many surfaces such as ice and hard packed snow require much longer stopping distances. Be alert, plan ahead and begin decelerating early. Improper use of the brake can cause the drive track to lose traction, reducing control and increasing the possibility of an accident.

TURNING For most snow surfaces, body English is the key to turning. As you approach a curve, slow down and begin to turn the handlebars in the desired direction. As you do so, put your weight on the running board to the inside of the turn and lean your upper body into the turn. This procedure should be practiced at slow speed many times in a large flat area with no obstacles. Once you have learned this technique, you should be able to perform it at higher speeds or in tighter curves. Lean more as the turn gets sharper or is made at higher speeds.

852-001

7-7

Improper riding procedures such as abrupt throttle changes, excessive braking, incorrect body movements, or too much speed for the sharpness of the turn may cause the snow- mobile to tip. If your snowmobile begins to tip while turning, lean more into the turn to regain balance. If necessary, gradually let off on the throttle and/or steer to the outside of the turn.

Remember: Avoid higher speeds until you are thoroughly familiar with the operation of your snowmobile.

RIDING UPHILL You should practice first on gentle slopes. Try more difficult climbs only after you have developed your skill. As you approach a hill, accelerate before you start the climb, and then reduce the throttle opening to prevent track slippage. It is also important to keep your weight on the uphill side at all times. On climbs straight up the hill this can be accom- plished by leaning forward and, on steeper inclines, stand- ing on the running boards and leaning forward over the handlebars. (Also see CROSSING A SLOPE.) Slow down as you reach the crest of the hill, and be prepared to react to obstacles, sharp drops, or other people or vehicles which may be on the other side. If you are unable to continue up a hill, do not spin the track. Stop the engine and set the parking brake. Then pull the rear of the snowmobile around to point the machine back down the hill. Do not get on the downhill side of the machine. When the snowmobile is pointed downhill, re- start the engine, release the parking brake, and descend the hill.

WARNING

Side hills and steep slopes are not recommended for a beginner or novice snowmobiler.

852-002

7-8

RIDING DOWNHILL When riding downhill, keep speed to a minimum. It is important to apply just enough throttle to keep the clutch engaged while descending the hill. This will allow you to use engine compression to help slow the machine, and to keep the snowmobile from rolling freely down the hill. Also apply the brake frequently, with light pressure.

WARNING

Use extra caution when applying the brake during descent. Excessive braking will cause the track to lock and will cause a loss of control.

CROSSING A SLOPE (SIDE HILL)

WARNING

Side hills are not recommended for a beginner or novice snowmobiler.

Crossing the face of a slope (side hill) requires you to properly position your weight to maintain proper balance. As you travel across the slope, lean your body to position your weight towards the uphill side. A recommended riding position is to kneel with the knee of the downhill leg on the seat and the foot of the uphill leg on the running board. This position will make it easier for you to shift your body weight as needed. Snow and ice are slippery, so be prepared for the possibil- ity that your snow-mobile could begin to slip sideways on the slope. If this happens, steer in the direction of the slide if there are no obstacles in your path. As you regain proper balance, gradually steer again in the direction you wish to travel.

If your snowmobile starts to tip, steer down the hill to regain balance.

WARNING

If you are unable to maintain correct balance, and your snowmobile is going to tip over, dismount your snow- mobile immediately on the uphill side.

ICE OR ICY SURFACE Operating on ice or icy surfaces can be very dangerous. Traction for turning, stopping or starting is much less than that on snow.

WARNING

When you have to operate on ice or icy surfaces, drive slowly and cautiously. Avoid rapid acceleration, turn- ing or braking. Steering is minimal and uncontrolled spins are an ever-present danger.

HARD-PACKED SNOW It can be more difficult to negotiate on hard-packed snow as both skis and track do not have as much traction. Avoid rapid acceleration, turning or braking.

OPERATION ON SURFACES OTHER THAN SNOW OR ICE Operation of your snowmobile on surfaces other than ice or snow should be avoided. Operation under such condi- tions will damage or result in rapid wear of ski runners, drive track, slide runners and drive sprockets. Operation of the machine under the following conditions should be avoided at all costs: 1. Dirt 2. Sand 3. Rocks 4. Grass 5. Bare pavement

Other conditions that should be avoided for the sake of drive track and slide runner life are: 1. Glare ice surfaces 2. Snow mixed with a lot of dirt and sand All the above conditions have one thing in common in regard to drive track and slide runners; little or no lubricat- ing ability. Drive track and all slide rail systems require lubrication (snow or water) between the plastic runners and the metal track inserts. In the absence of lubrication, the plastic runners will rapidly wear and in severe cases, literally melt away, and the drive track will be subjected to damage and/or failure. Also, traction aids such as studs, cleats etc., may cause further track damage and/or failure.

7-10

WARNING

Drive track damage and/or failure could result in loss of braking ability and machine control, which could cause an accident. Always check the drive track for damage or

misadjustment before operating the machine. Do not operate the machine if you find damage to

the drive track.

CAUTION: Be sure to ride on the fresh snow frequently to avoid rapid wear and damage of the drive track and slide runners when operating under ice or hard packed snow conditions.

TRANSPORTING When transporting your machine on a trailer or in a truck, observe the following recommendations to help protect your machine from damage: Make sure the fuel level in the fuel tank is lower than the

carburetors. Otherwise, the vibration and bumps from the road surface could make it possible for fuel to flow through the carburetor into the crankcase. This can result in hydrostatic lock, a condition where the engine cannot rotate because of fuel accumulated in the en- gine. Severe engine damage can result from hydro- static lock. When possible, the fuel tank should be empty during transportation, especially if the trip will be 30 minutes or longer.

If transporting the machine in an open trailer or truck, put a tight fitting cover on the machine. A cover specifi- cally designed for your snowmobile is best. This will help keep foreign objects out of the cooling vents in the shroud, and also help protect the machine against damage from debris on the road.

If transporting the machine in an open trailer or truck in areas where road salt is used, coat metal suspension surfaces lightly with oil or other protectant. This will help protect against corrosion. Be sure to clean the machine when you get to your destination to remove any corro- sive salts.

SPARK PLUG INSPECTION The spark plug is an important engine component and is easy to inspect. The condition of the spark plug can indicate something of the condition of the engine. Check the coloration on the white porcelain insulator around the center electrode. The ideal coloration at this point is a medium to a light tan color for a machine that is being ridden normally. If a spark plug shows a distinctly different color, there could be something wrong with the engine. For example, a very white center electrode porcelain color could indicate an intake track air leak or carburetion problem for that cylinder. Do not attempt to diagnose such problems yourself. Instead, take the machine to your Yamaha dealer. You should periodically remove and in- spect the spark plug because heat and deposits will cause any spark plug to slowly break down and erode. Consult your dealer before changing to a different type of spark plug.

Standard spark plug: BR250T

BR8HS (NGK) CS340E/ET410TR/VK540E

BR9ES (NGK)

Spark plugs are produced in several different thread lengths. The thread length (reach) is the distance from the spark plug gasket seat to the end of the threaded portion. If the reach is too long, overheating and engine damage may result. If the reach is too short, spark plug fouling and poor performance may result. Also, if too short, carbon will form on the exposed threads resulting in combustion chamber hot spots and thread damage. Always use a spark plug with the proper reach.

Spark plug reach 1: BR250T

HIGH ALTITUDE ADJUSTMENTS Operating at high altitude reduces the performance of a gasoline engine, about 3% for every 305 m (1000 ft) of elevation. This is because there is less air as altitude increases. Less air means less oxygen available for com- bustion. Your snowmobile can be adjusted to overcome most of the problems found in high altitude riding. Carburetor adjust- ments are the most important. Less air at high altitude makes the fuel/air ratio too rich, which can cause poor performance. Common problems are hard starting, bog- ging, and plug fouling. Follow the Main Jet Setting chart which is available at an authorized Yamaha dealer care- fully. Proper carburetion adjustments will correct the fuel/ air ratio.

Remember: less air at higher altitude means there is less horsepower available, even with proper carburetion. Ex- pect acceleration and top speed to be reduced at higher altitudes. To overcome operating with less power at high altitudes, your snowmobile may also require different clutch and driveline settings to avoid poor performance and rapid wear. If you plan to operate your snowmobile at an altitude different from the area where you bought your machine, be sure to consult your Yamaha dealer. He can tell you if there are any changes necessary for the altitude where you plan to ride.

CAUTION: The drive chain gears and V-belt clutch should be adjusted when operating over 900 m (3000 ft) high altitude. Consult a Yamaha dealer.

TRACK ADJUSTMENT

WARNING

A broken track, track fittings, or debris thrown by the track could be dangerous to an operator or bystanders. Observe the following precautions: Do not allow anyone to stand behind the machine

when the engine is running. When the rear of the machine is raised to allow the

track to spin, a suitable stand must be used to support the rear of the machine. Never allow any- one to hold the rear of the machine off the ground to allow the track to spin. Never allow anyone near a rotating track.

Inspect track condition frequently. Replace dam- aged track guide clips. Replace the track if it is damaged to the depth where fabric reinforcement material is visible or support rods are broken. Oth- erwise, track damage and/or failure could result in loss of braking ability and machine control, which could cause an accident.

Never install studs (cleats) closer than three inches from the edge of the track.

Track Deflection Measurement 1. Lay the machine on its side. 2. Measure the track deflection with a spring scale. Pull at

the center of the track with a force of 100 N {10 kg (22 lb)}.

NOTE: Measure the gap between the slide runner and the edge of the track window. Measure both sides.

STORAGE Long term storage, requires some preven- tive procedures to guard against deteriora- tion.

1. Cleaning Thoroughly clean the machine, inside and out, to remove the corrosive salts and acids that can accumulate. Use Yamaha Mud and Grease Release, or an equivalent, to loosen mud, grease and grime. Wash with mild soap, then rinse and dry completely.

2. Lubrication Lubricate moving parts, suspension link- age and pivot points. Use the grease or lubricant specified in the MAINTENANCE section, or Yamaha Lube-Zall general purpose lubricant. Proper lubrication fights corrosion while it reduces friction.

3. Fuel system preparation Add Yamaha Fuel Conditioner/Stabilizer, or an equivalent, to the fuel tank to help prevent fuel oxidation, gum and varnish deposits, and to inhibit corrosion in the fuel system and carburetor. In areas where oxygenated fuel (gasohol) is used, completely drain the fuel system. Consult your Yamaha dealer.

4. Engine Proper storage of the engine is essential to prevent costly rust and corrosion dam- age to internal engine components. This is more important than ever in those areas where oxygenated fuel (gasohol) is used, because the alcohol content in the fuel increases the chance for water to enter the engine. Use Yamaha Stor-Rite Fogging Oil, or an equivalent, to protect both combustion chamber and crank-

shaft from corrosion. An alternate method is to remove the airbox and squirt oil into the carburetor throats while the engine is running.

CAUTION: Do not attempt to store the machine by simply starting the engine occasionally during the storage period. This can cause more harm than good! Moisture and acids form during combustion which can actually increase the chance for corro- sion damage during the storage period.

5. Protection Apply a coat of wax, such as Yamaha Silicone Wax, to painted surfaces. Spray Yamaha Silicone Spray, or an equivalent protectant, on the exterior of the engine, on the track, and on other metal, plastic and rubber parts.

6. Battery (CS340E/VK540E) Remove the battery from the machine and check the fluid level. Charge the battery. Store it in a cool, dry place that is above 0C (32F), but less than 30C (90F). Check battery condition with a hydrometer monthly, and charge as nec- essary.

WARNING

Never smoke or make and break con- nections at the battery while charging. Sparks may ignite the battery gas.

Be sure the battery terminals are tight and that the battery vent tube is prop- erly routed and is securely attached to the battery.

10-2

CAUTION: Do not charge battery quickly. Charge for 10 hours at 1.4 amperes. (CS340E) Do not charge battery quickly. Charge for 10 hours at 1.6 amperes. (VK540E)

7. Track Loosen the track, and block up the chas- sis so that the track is suspended above the ground.

8. Drive belt Remove the drive belt and store sepa- rately.

9. Storage Store the machine in a dry, well-venti- lated place out of direct sunlight. Put a fabric (breathable) cover over it, prefer- ably one designed for your machine. Do not use a plastic or vinyl cover conden- sation could be trapped underneath which could increase the chance of rust- ing.

RETURN TO SERVICE AFTER STORAGE

When returning your machine to service, reinstall the drive belt and adjust the track. Reinstall the battery, and make sure the battery vent tube is properly reinstalled and is not kinked. Remove the spark plugs and clean them or replace them. Perform all other pre-opera- tion and seasonal maintenance listed in the Periodic Maintenance chart.

For peak performance, it is recommended that you have your machine checked and tuned by your Yamaha dealer. He has the experience and training to help you get the maximum performance and use from your Yamaha.
