Engine break-inThere is never a more important period in thelife of your machine than the period betweenzero and 20 hours. For this reason, we ask that you carefully readthe following material.

During this period, prolonged full throttle oper-ation or any condition which might result in ex-cessive engine heating must be avoided.However, momentary (2–3 seconds maxi-mum) full throttle operation under load doesnot harm the engine.

CROSSING A SLOPE Traversing a sloping surface on your ATV re-quires you to properly position your weight tomaintain proper balance. Be sure that youhave learned the basic riding skills on flatground before attempting to cross a slopingsurface. Avoid slopes with slippery surfacesor rough terrain that may upset your balance.

As you travel across a slope, lean your bodyin the uphill direction. It may be necessary tocorrect the steering when riding on loose sur-faces by pointing the front wheels slightly up-hill. When riding on slopes be sure not tomake sharp turns either up or down hill.

If your ATV does begin to tip over, graduallysteer in the downhill direction if there are noobstacles in your path. As you regain properbalance, gradually steer again in the directionyou wish to travel.

NOTE:_

The air filter element should be cleaned every20–40 hours. It should be cleaned and lubri-cated more often if the machine is operated inextremely dusty areas. Each time the air filterelement maintenance is performed, check theair inlet to the filter case for obstructions.Check the air filter case rubber joint to the car-buretor and manifold fittings for an airtightseal. Tighten all fittings securely to avoid thepossibility of unfiltered air entering the engine. _

CAUTION:_

Never operate the engine with the air filterelement removed. This will allow unfilteredair to enter, causing rapid engine wear andpossible engine damage. Additionally, op-eration without the air filter element will af-fect carburetor jetting with subsequentpoor performance and possible engineoverheating. _

TroubleshootingAlthough Yamaha machines receive a rigid in-spection before shipment from the factory,trouble may occur during operation. Any prob-lem in the fuel, compression, or ignition sys-tems can cause poor starting and loss ofpower. The troubleshooting chart describes aquick, easy procedure for making checks. Ifyour machine requires any repair, take it to aYamaha dealer.The skilled technicians at a Yamaha dealer-ship have the tools, experience, and know-how to properly service your machine. Useonly genuine Yamaha parts on your machine.Imitation parts may look like Yamaha parts,but they are often inferior. Consequently, theyhave a shorter service life and can lead to ex-pensive repair bills.

prevent water entry. A plastic bag andstrong rubber band may be used.

b. Make sure the spark plug and all fillercaps are properly installed.

2. If the engine case is excessively greasy,apply degreaser with a paint brush. Donot apply degreaser to the wheel axles.

3. Rinse the dirt and degreaser off with agarden hose. Use only enough pressureto do the job.
