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.

3-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 oper-

ating this snowmobile. Become familiar with all of the operating controls and their function. Consult a Yamaha dealer about any control or function you do not understand.

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

3. BR250T is designed to carry the OPERATOR ONLY. Passengers are prohibited. Carrying a passenger can cause loss of control.

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

5. For safety and proper care of the snowmobile, always perform the pre-operation checks on pages 6-16-6 before starting the engine. Check the throttle, brake, and steering for proper operation every time before starting the engine. Make sure that the throttle lever moves freely and it returns to the home position when it is released.

6. Apply the parking brake before starting the engine. Never drive the snowmobile with the parking brake applied. This may overheat the brake disc and reduce braking ability.

3-1

E_8bd.book Page 2 Monday, May 17, 2010 4:22 PM

3-2

7. Do not allow anyone to stand behind the snowmobile when starting, inspecting, or adjusting the snowmo- bile. 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 that the fuel tank cap is closed securely after refueling. Wipe up any spilled fuel immedi- ately.

9. If you swallow some gasoline, inhale a lot of gasoline vapor, or get some gasoline into your eyes, 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 qual- ity snowmobile suit, boots, and a pair of gloves or mit- tens 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 snowmobile 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.

E_8bd.book Page 3 Monday, May 17, 2010 4:22 PM

3-3

3. This snowmobile 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 snowmobile.

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

5. Always ride with other snowmobilers 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 gentlynot suddenly.

Maintenance and storage 1. When laying the snowmobile on its side for mainte-

nance, use a suitable stand to keep it in a stable and level position.

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

3. Never store the snowmobile with fuel in the fuel tank inside a building where ignition sources are present such as hot water and space heaters, an open flame, sparks, clothes dryers, and the like. Allow the engine to cool off before storing the snowmobile in an enclosed space.

4. Always refer to the STORAGE section if the snow- mobile is to be stored for an extended period of time.

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

Break-in There is never a more important period in the life of your snowmobile than the break-in period. For the first 10 hours, approximately 200 km (125 mi), do not put an excessive load on the engine. Avoid prolonged full throt- tle operation. Also avoid lugging the engine, such as laborious opera- tion in wet snow. If any abnormal condition is noticed, such as excessive vibration or noise, consult a Yamaha dealer.

TIP @

To ensure proper engine break-in, use a 50:1 gasoline/oil mixture when filling the fuel tank of a new snowmobile for the first time. For example: 10 L of gasoline per 0.2 L of oil (1 gal of gasoline per 2.6 oz of oil) equals a 50:1 mixing ratio. (See pages 6-16-2 for the recommended gasoline and oil.) @

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 tech- niques well before attempting more difficult maneuvers. Riding your new snowmobile can be a very enjoyable activity, providing you with hours of pleasure. However, it is essential to familiarize yourself with the operation of the snowmobile to achieve the skill neces- sary to enjoy riding safely. Before operating the snowmobile, read this Owners Manual completely and understand the operation of the controls. Pay particular attention to the safety infor- mation on pages 3-13-3. Please read all warning and notice labels on your snow- mobile. Also, read the Snowmobilers Safety Handbook that is supplied with your snowmobile.

Learning to ride your snowmobile Before you ride, always perform the pre- operation checks listed on pages 8-18-3. The short time spent checking the condi- tion of the snowmobile will be rewarded with added safety and a more reliable snowmobile. Always wear the proper cloth- ing for both warmth and to help protect you from injury if an accident occurs. Become familiar with operating your snow- mobile at low speeds, even if you are an experienced rider. Do not attempt to oper- ate at maximum performance until you are

7-

totally familiar with the snowmobiles han- dling 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.

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

To start out and accelerate 1. With the engine idling, release the

parking brake. 2. Apply the throttle slowly and smoothly.

The V-belt clutch will engage and you will start to accelerate.

WARNING @

The operator should always keep both hands on the handlebar. Never put your feet outside the running boards. Avoid high speeds until you have become thoroughly familiar with your snowmo- bile 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.

4

E_8bd.book Page 5 Monday, May 17, 2010 4:22 PM

Improper use of the brake can cause the drive track to lose traction, reduce control, and increase 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 handlebar 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 low speeds many times, in a large flat area with no obstacles. Once you have learned this technique, you should be able to per- form it at higher speeds or in tighter curves. Lean more as the turn gets sharper or is made at higher speeds. Improper riding techniques such as abrupt throttle changes, excessive braking, incor- rect body movements, or too much speed for the sharpness of the turn may cause the snowmobile to tip. If your snowmobile begins to tip while turn- ing, lean more into the turn to regain bal- ance. If necessary, gradually let off on the throttle or steer to the outside of the turn.

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

7-

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 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 accomplished by leaning forward and, on steeper inclines, standing on the running boards and leaning forward over the han- dlebar. (Also see Traversing a slope.) Slow down as you reach the crest of the hill, and be prepared to react to obstacles, sharp drops, or other vehicles or people 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 snowmo- bile around to point the snowmobile back down the hill. When the snowmobile is pointed downhill, mount your snowmobile from the uphill side. Restart the engine, release the parking brake, and descend the hill.

WARNING @

Side hills and steep slopes are not rec- ommended for a novice snowmobiler. @

5

E_8bd.book Page 6 Monday, May 17, 2010 4:22 PM

Riding downhill

When riding downhill, keep speed to a min- imum. 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 snowmobile, 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 a descent. Excessive braking will cause the drive track to lock, causing a loss of control. @

Traversing a slope

WARNING @

Traversing slopes is not recommended for a novice snowmobiler. @

Traversing a slope requires you to properly position your weight to maintain proper bal- ance. 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 your

7-

downhill leg on the seat and the foot of your 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 possibility that your snowmobile 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 snowmobile immediately on the uphill side. @

Ice or icy surface Operating on ice or icy surfaces can be very dangerous. Traction for turning, stop- ping, and starting is much less than that on snow.

WARNING @

When you have to operate on ice or icy surfaces, drive slowly and cautiously. Avoid accelerating, turning, and brak- ing rapidly. Steering is minimal and uncontrolled spins are an ever-present danger. @

6

E_8bd.book Page 7 Monday, May 17, 2010 4:22 PM

Hard-packed snow It can be more difficult to negotiate on hard-packed snow as both the skis and drive track do not have as much traction as when the snowmobile is operated on fresh snow. Avoid rapid acceleration, turning, and braking.

Operation on surfaces other than snow or ice Operation of your snowmobile on surfaces other than snow or ice should be avoided. Operation under such conditions will dam- age or result in rapid wear of the ski run- ners, drive track, slide runners, and drive sprockets. Operation of the snowmobile on the following surfaces should be avoided at all times: 1. Dirt 2. Sand 3. Rocks 4. Grass 5. Bare pavement

Other surfaces 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 of the above surfaces have one thing in common in regard to drive track and slide runners; little or no lubricating ability. Drive track and all slide rail systems require lubrication (snow or water) between the slide runners and the slide metal. In the absence of lubrication, the slide runners will rapidly wear and in severe cases, liter- ally melt away, and the drive track will be subject to damage or failure. Also traction aids such as studs, cleats, etc., may cause further track damage or failure.

7-

WARNING @

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

damage or maladjustment before operating the snowmobile.

Do not operate the snowmobile if you find damage to the drive track.

@

NOTICE @

Ride on fresh snow frequently. Operat- ing on ice or hard-packed snow will rap- idly wear the slide runners. @

E_8bd.book Page 8 Monday, May 17, 2010 4:22 PM

ESU02510

Maximizing drive track life Recommendations

Track tension During initial break-in, the new drive track will tend to stretch quickly as the track settles. Be sure to correct the track tension and alignment frequently. (See pages 8-148-16 for adjustment procedures.) A loose track can slip (ratchet), derail or catch on suspension parts causing severe damage. Do not overtighten the drive track, otherwise it may increase the friction between the track and the slide runners, resulting in the rapid wear of both components. Also, this may put an excessive load on the suspension components, resulting in component failure.

Marginal snow The drive track and the slide runners are lubricated and cooled by snow and water. To prevent the drive track and slide runners from overheating, avoid sustained high- speed usage in areas such as icy trails, frozen lakes and rivers that have minimal snow coverage. An overheated track will be weakened internally, which may cause fail- ure or damage.

Off-trail riding Avoid off-trail riding until there is sufficient snow cover- age. It generally takes several feet of snow to provide a good overall base to properly cover debris, such as rocks, logs, etc. If snow coverage is not sufficient, stay on trails to avoid impact damage to the drive track.

Studded track In general, track life will be shortened when studs are installed. Drilling stud holes into the drive track will cut the internal fibers, which weakens the track. Avoid spin- ning the drive track. Studs may catch on an object and pull out of the track, leaving tears and damage around the already weakened area. To minimize possible dam- age, consult your stud manufacturer for installation and stud pattern recommendations. Yamaha does not recommend track studding.

Transporting When transporting your snowmobile on a trailer or in a truck, observe the following recommendations to help protect it from damage: Make sure that the fuel level in the fuel tank is lower

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

If transporting the snowmobile in an open trailer or truck, put a tight fitting cover on the snowmobile. A cover specifically 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 snowmobile against damage from debris on the road.

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

Tool kit The owners tool kit has the tools which are sufficient for most periodic maintenance and minor repair. A torque wrench is also necessary to properly tighten nuts and bolts.

1 Tool kit

NOTICE @

Before starting the engine, make sure that the tool kit is firmly seated in the holder and is secured with the holding band. @

TIP @

If you do not have a torque wrench available during a service operation requiring one, take your snowmobile to a Yamaha dealer to check the torque settings and adjust them if necessary. @

ESU01443

Checking the spark plug The spark plug is an important engine component and is easy to inspect. The condition of the spark plug can indi- cate 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 snowmobile 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 indi- cate an intake track air leak or carburetion problem for that cylinder. Do not attempt to diagnose such problems yourself. Instead, take the snowmobile to a Yamaha dealer for inspection and possible repairs. You should periodically remove and inspect the spark plug because heat and deposits will cause a spark plug to slowly break down and erode. Consult a Yamaha dealer before chang- ing to a different type of spark plug.

Specified spark plug: BR8HS (NGK)

Spark plugs are produced in several different thread lengths. The thread length or 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 the reach is 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 speci- fied reach.

Before installing any spark plug, measure the electrode gap with a wire thickness gauge and adjust to specifica- tion.

When installing the spark plug, always clean the gasket surface. Wipe off any grime from the threads and tighten the spark plug to the specified torque.

Adjusting the carburetor

NOTICE @

It is advisable to have a Yamaha dealer make this adjustment.

Make sure that the carburetor silencer is installed before starting the engine to prevent engine dam- age.

@

The carburetor settings may have to be changed due to changes in air temperature and elevation, and use of oxygenated fuels such as gasohol.

NOTICE @

The drive chain gears and V-belt clutch must also be adjusted when operating at altitudes above 900 m (3,000 ft). See Adjusting the high altitude settings for details. @

Replacing a main jet Replace the main jet according to the setting chart which is available at a Yamaha dealer.

WARNING @

Never remove the drain plug or the float chamber while the engine is hot. Fuel will flow out from the float chamber, and could ignite and cause injury.

Adjusting the high altitude settings Operating at high altitude reduces the performance of a gasoline engine to about 3% for every 305 m (1,000 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 adjustments are the most important. Less air at high alti- tude makes the air/fuel ratio too rich, which can cause poor performance. Common problems are hard starting, bogging, and plug fouling. Follow the Main Jet Setting chart which is available at a Yamaha dealer carefully. Proper carburetion adjustments will correct the air/fuel ratio. Remember: less air at higher altitude means there is less horsepower available, even with proper carburetion. Expect accelera- tion and top speed to be reduced at higher altitudes. To overcome operating with less power at high altitudes, your snowmobile may also require different settings for the drive chain gears and V-belt clutch to avoid poor per- formance and rapid wear. If you plan to operate your snowmobile at an altitude different from the area where you bought it, be sure to consult a Yamaha dealer. They can tell you if there are any changes necessary for the altitude where you plan to ride.

NOTICE @

The drive chain gears and V-belt clutch should be adjusted when operating over a high altitude of 900 m (3,000 ft). Consult a Yamaha dealer. @

Adjusting the drive track

WARNING @

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

mobile when the engine is running. When the rear of the snowmobile is raised to

allow the drive track to spin, a suitable stand must be used to support the rear of the snowmo- bile. Never allow anyone to hold the rear of the snowmobile off the ground to allow the drive track to spin. Never allow anyone near a rotating drive track.

Inspect the drive track condition frequently. Replace any damaged slide metal. Replace the drive track if it is damaged to the depth where fabric reinforcement material is visible or support rods are broken. Otherwise, track damage or fail- ure could result in loss of braking ability and snowmobile control, which could cause an acci- dent.

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

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

NOTICE @

Improper cleaning can damage plas- tic parts such as shroud, covers, windshields, headlight lenses, meter lenses, etc. Use only a soft, clean cloth or sponge with mild detergent and water to clean plastic.

Do not use any harsh chemical prod- ucts 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 deteriora- tion in the following areas: seals (of the slide rail suspension, front sus- pension and brakes), electric com- ponents (couplers, connectors, instruments, switches and lights), breather hoses and vents.

For snowmobiles equipped with a windshield: Do not use strong clean- ers 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.

@

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-pur- pose lubricant. Proper lubrication fights corrosion while it reduces friction.

3. Fuel system preparation Add Yamaha Fuel Stabilizer and Condi- tioner, or an equivalent stabilizer, to the fuel tank to help prevent fuel oxidation and gum and varnish deposits, and to inhibit corrosion in the fuel system and carbure- tor. In areas where oxygenated fuel (gaso- hol) is used, completely drain the fuel system. Ask a Yamaha dealer if further information is needed.

4. Engine Proper storage of the engine is essential to prevent costly rust and corrosion damage to internal engine components. This is more important in 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 Engine Fogging Oil, or an equiva- lent fogging oil, to protect both the com- bustion chamber and crankshaft from corrosion. An alternate method is to remove the carburetor silencer and squirt oil into the carburetor throats while the engine is running.

10-1

E_8bd.book Page 2 Monday, May 17, 2010 4:22 PM

NOTICE @

Do not attempt to store the snowmobile by simply starting the engine occasion- ally during the storage period. This can cause more harm than good! Moisture and acids form during combustion which can actually increase the chance for corrosion damage during the stor- age period. @

5. Protection Apply a coat of wax to painted surfaces. Apply suitable protectants to the exterior of the engine, drive track, and to other metal, plastic, and rubber parts.

6. Drive track Loosen the drive track and block up the chassis so that the track is suspended above the ground.

7. V-belt Remove the V-belt and store separately.

8. Storage Store the snowmobile in a dry, well-venti- lated place out of direct sunlight. Put a fab- ric cover over the snowmobile, preferably one that is designed for it. Do not use a plastic or vinyl covercondensation could be trapped underneath which could increase the chances of rusting.

Returning to service after storage When returning your snowmobile to ser- vice, reinstall the V-belt and adjust the drive track. Remove the spark plugs and clean or replace them if necessary. Per- form all other pre-operation and seasonal maintenance checks listed in the periodic maintenance chart.

For peak performance, it is recommended that you have your snowmobile checked and tuned by a Yamaha dealer. They have the experience and training to help you get the maximum performance and use of your Yamaha snowmobile.
