Safety information

ESU10193

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

● Read the Owner’s Manual and all labels.

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

● Wear protective clothing. Wear an ap-

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

creases the possibility of an accident or equipment damage. See page 55 for a list of pre-operation checks.

● 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.

While using your snowmobile

● This snowmobile was not manufactured for

use on public streets, roads, or highways. Such use is prohibited by law, and you could collide with another vehicle.

● RS90P and RS90PLT are designed to carry

the OPERATOR ONLY. Passengers are prohibited. Carrying a passenger can cause loss of control.

● Do not operate the snowmobile after or

while drinking alcohol or taking drugs. Your ability to operate the snowmobile is reduced by the influence of alcohol or drugs.

Prepare your snowmobile

● 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 in-

● 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.

● 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.

Safety information

● 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.

● Many surfaces such as ice and hardpacked

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.

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 be unable to save yourself. Also, deadly levels of carbon monoxide can linger for hours or days in enclosed or poorly-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 the 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 the engine in poorly ventilated or

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

● Do not run the engine outdoors where en-

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

Genuine Yamaha Accessories

Choosing accessories for your snowmobile 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 snowmobile. 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.

Maintenance and storage

● When laying the snowmobile on its side for

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

● Do not leave the snowmobile on its left side

for an extended period of time. Fuel may leak out from the fuel breather hose.

● Do not allow anyone to stand behind the

snowmobile when starting, inspecting, or adjusting the snowmobile. A broken track, track fittings, or debris thrown by the track could be dangerous to the operator or bystanders.

● Modifications made to the snowmobile not

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

● 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.

If the T.O.R.S. is activated, make sure that the cause of the malfunction has been corrected and that the engine can be operated without a problem before restarting the engine. Continuing to operate with a malfunction could cause loss of control or damage.

If the throttle valves or throttle cable malfunctions during operation, the T.O.R.S. will be activated when the throttle lever is released. The T.O.R.S. is designed to override the fuel injection (RS90P / RS90PLT / RST90PGT / RST90PTF) or ignition (RST90) and limit the engine speed to less than the clutch engagement speed if the throttle valves fail to return to the idle position when the throttle lever is released.

WARNING

Fuel

EWS00071

Gasoline and gasoline vapors are extremely flammable. To avoid fires and explosions and to reduce the risk of injury when refueling, follow these instructions.

Make sure there is sufficient gasoline in the tank.

1. Before refueling, turn off the engine and be sure that nobody is on the snowmobile. Never refuel while smoking, or while in the vicinity of sparks, open flames, or other sources of ignition such as the pilot lights of water heaters and clothes dryers.

2. Do not overfill the fuel tank. Stop filling when the fuel reaches the bottom of the filler tube. Because fuel expands when it heats up, heat from the engine or the sun can cause fuel to spill out of the fuel tank.

Control functions

1. Filler tube

2. Maximum fuel level

3. Wipe up any spilled fuel immediately.

4. Be sure the fuel tank cap is closed securely by turning it clockwise.

EWS00680

Gasoline is poisonous and can cause injury or death. Handle gasoline with care. Never siphon gasoline by mouth. If you should swallow some gasoline or inhale a lot of gasoline vapor, or get some gasoline in your eyes, see your doctor immediately. If gasoline spills on your skin, wash with soap and water. If gasoline spills on your clothing, change your clothes.

● Make sure that snow or ice does not en-

ter the fuel tank when refueling.

● The fuel tank should be filled with the

recommended gasoline. The use of other gasoline will cause severe damage to

internal engine parts, such as the valves and piston rings, as well as to the exhaust system.

For CANADA

● Oxygenated fuels (gasohol) containing

a maximum 10% of ethanol (E10) can be used, although richer jetting may be required to prevent engine damage. Consult a Yamaha dealer. Gasohol containing methanol is not recommended.

● Do not use alcohol deicers or water ab-

sorbing additives with oxygenated fuel.

Suspension

The suspension can be adjusted to suit rider preference. Softer settings, for example, may provide greater rider comfort, while harder settings may allow more precise handling and control over certain types of terrain or riding conditions. If you are not familiar with suspension adjustments, have a Yamaha dealer make these adjustments.

EWS00151

Read and understand the following information before handling shock absorbers that contain highly pressurized nitrogen gas.

● Do not tamper with or attempt to open

the cylinder assemblies.

● Do not subject the shock absorbers to

an open flame or other high heat source. This may cause the unit to explode due to excessive gas pressure.

● Do not deform or damage the cylinders

in any way. Cylinder damage will result in poor damping performance.

● Do not dispose of a damaged or worn

Riding your snowmobile

Getting to know your snowmobile

EWS00211

To avoid severe injury or death:

● Keep both hands on the handlebar dur-

ing operation.

● Never put your feet outside the running

boards.

● Avoid higher speeds or more difficult

maneuvers until you have become thoroughly familiar with your snowmobile and all of its controls.

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. However, it is essential to familiarize yourself with the operation of the snowmobile to achieve the skill necessary to enjoy riding safely. Before operating the snowmobile, read this Owner’s Manual completely and understand the operation of the controls.

Operation

WARNING

Pay particular attention to the safety information on page 13. Please read all warning and notice labels on your snowmobile. Also, read the Snowmobiler’s Safety Handbook that is supplied with your snowmobile (for Canada).

Learning to ride your snowmobile

Before you ride, always perform the pre-operation checks listed on page 55. The short time spent checking the condition of the snowmobile 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 operating your snowmobile at low speeds, even if you are an experienced rider. Do not attempt to operate at maximum performance until you are totally familiar with the snowmobile’s 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. Set the parking brake and follow the instructions on page 57 to start the engine. Once the engine has warmed up, you are ready to begin riding your snowmobile.

A broken track, track fittings, or debris thrown by the track could be dangerous to bystanders.

[EWS00690]

Braking

EWS00220

● 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, reduce control, and increase the possibility of an accident.

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

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.

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! Do not

allow anyone to stand behind the snowmobile when starting the engine.

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 perform it at high-

er speeds or in tighter curves. Lean more as

WARNING

the turn gets sharper or is made at higher speeds. Improper riding techniques such as abrupt throttle changes, excessive braking, incorrect 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 turning, lean more into the turn to regain balance. If necessary, gradually let off on the throttle 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

EWS00231

Operation on slopes can lead to loss of control if proper techniques are not used. Follow these instructions to reduce your risk of an accident. Do not try steeper or more difficult inclines until you have developed your skill on gentle slopes.

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 handlebar. (Also see “Traversing a slope”.)

Operation

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 snowmobile 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.

Riding downhill

EWS00240

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

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 snowmobile, and to keep the snowmobile from rolling freely down the hill. Also apply the brake frequently, with light pressure.

Operation

WARNING

Traversing a slope

EWS00251

Driving across the face of a slope (“sidehilling”) can lead to overturn or loss of control if proper techniques are not used. Follow these instructions to reduce your risk of an accident. Do not try steeper or more difficult inclines until you have developed your skill on gentle slopes.

Traversing a slope 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 your 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 to avoid being hit or caught under the snowmobile as it tips over.

[EWS00261]

Ice or icy surface

EWS00270

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

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

Hard-packed snow

It can be more difficult to negotiate on hardpacked 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 damage or result in rapid wear of the ski runners, drive

Operation

WARNING

NOTICE

track, slide runners, and drive sprockets. Operation of the snowmobile on the following surfaces should be avoided at all times:

● Dirt

● Sand

● Rocks

● Grass

● Bare pavement

Other surfaces that should be avoided for the sake of drive track and slide runner life are:

● Glare ice surfaces

● 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, literally 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.

EWS00280

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.

ECS00350

Ride on fresh snow frequently. Operating on ice or hard-packed snow will rapidly wear the slide runners.

ESU11350

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 page 107 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 failure or damage.

Off-trail riding

Avoid off-trail riding until there is sufficient snow coverage. 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 spinning the drive track. Studs may catch on an object and pull out of the track, leaving tears and damage

Operation

WARNING

TIP

around the already weakened area. To minimize possible damage, 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:

● RST90: 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 carburetors into the cylinders. 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 takes longer than 30 minutes.

Operation

● 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, 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 another protectant. This will help protect against corrosion. Be sure to clean the snowmobile when you get to your destination to remove any corrosive salts.

Periodic maintenance and adjustment

WARNING

ESU13181

Periodic inspection, adjustment, and lubrication will keep your snowmobile in the safest and most efficient condition possible. Safety is an obligation of the vehicle owner/operator. The most important points of vehicle inspection, adjustment, and lubrication are explained on the following pages.

EWS00341

Failure to properly maintain the snowmobile or performing maintenance activities incorrectly may increase your risk of injury or death during service or while using the snowmobile. If you are not familiar with snowmobile service, have a Yamaha dealer perform service.

EWS00700

Turn off the engine when performing maintenance unless otherwise specified.

● A running engine has moving parts that can catch on body parts or clothing, and elec-

trical parts that can cause shocks or fires.

● Running the engine while servicing can lead to eye injury, burns, fire, or carbon mon-

oxide poisoning–possibly leading to death. See page 13 for more information about carbon monoxide.

Checking the spark plugs

The spark plugs are important engine components and are easy to inspect. The condition of the spark plugs can indicate 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-tolight tan color for a snowmobile that is being ridden normally. If any 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 snowmobile to a Yamaha dealer for inspection and possible repairs. You should periodically remove and inspect the spark plugs because heat and deposits will cause any spark plug to slowly break down and erode. Consult a Yamaha dealer before changing to a different type of spark plug.

Specified spark plug:

Manufacturer:

NGK

Model:

CR8E

EWS00710

Be sure to use the specified spark plug and spark plug cap. Otherwise, the T.O.R.S. may not work properly.

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 specified reach.

Carburetors (RST90)

The carburetors are an important part of the engine and its emission control system, which require very sophisticated adjustment. Therefore, carburetor adjustments should be left to a Yamaha dealer, who has the necessary professional knowledge and experience.

ESU13980

High-altitude settings

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 combustion. RS90P / RS90PLT / RST90PGT / RST90PTF: Your snowmobile utilizes an electronic fuel injection system that delivers the optimal air/fuel ratio required by the engine. Therefore, the fuel injection system does not need to be adjusted, even for operation at high altitude. RST90: Your snowmobile can be adjusted to overcome most of the problems found in highaltitude riding. Carburetor adjustments are the most important. Less air at high altitude makes the air/fuel ratio too rich, which can cause poor performance. Common problems are hard starting, bogging, and plug fouling. Proper carburetion adjustments will correct the air/fuel ratio. Be sure to have a Yamaha dealer make these adjustments.

Periodic maintenance and adjustment

WARNING

NOTICE

TIP

Remember:

Less air at higher altitude means there is less horsepower available, even with the optimal air/fuel ratio. Expect 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 settings for the drive chain gears and V-belt clutch to avoid poor performance 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. The dealer 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 above a high altitude of 900 m (3000 ft). Consult a Yamaha dealer.

[ECS00431]

Valve clearance

The valve clearance changes with use, resulting in improper air-fuel mixture and/or engine noise. To prevent this from occurring, the valve clearance must be adjusted by a Yamaha dealer at the intervals specified in the periodic maintenance chart.

ESU13797

Engine oil and oil filter cartridge

The engine oil level should be checked before each use. In addition, the oil must be changed and the oil filter cartridge replaced at the intervals specified in the periodic maintenance and lubrication chart.

EWS00370

Engine oil is extremely hot immediately after the engine is turned off. Coming into contact with or getting any engine oil on your clothes could result in burns.

ECS00482

● Do not run the engine with too much or

not enough oil in the oil tank. Oil could spray out or the engine could be damaged.

● Be sure to change the engine oil after

the first 800 km (500 mi) of operation, and every 4000 km (2500 mi) thereafter or at the start of a new season, otherwise the engine will wear quickly.

● The oil filter cartridge should be re-

placed after the first 800 km (500 mi) of operation, and every 20000 km (12000 mi) of operation thereafter.

To check the engine oil level

1. Place the snowmobile on a level surface and apply the parking brake.

2. Start the engine, warm it up for 10–15 minutes, and then turn it off.

● The engine can also be warmed up by driv-

ing the snowmobile for 10–15 minutes.

● After operating the snowmobile, allow the

engine to idle for at least 10 seconds before turning it off.
