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.

TURNING YOUR ATV To achieve maximum traction while riding off-road, the two rear wheels are mounted solidlyon one axle and turn together at the samespeed. Therefore, unless the wheel on the in-side of the turn is allowed to slip or lose sometraction, the ATV will resist turning.

If your ATV has stalled or stopped and you be-lieve you can continue up the hill, restart care-fully to make sure you do not lift the frontwheels which could cause you to lose control.If you are unable to continue up the hill, dis-mount the ATV on the uphill side. Physicallyturn the ATV around and then descend the hill.

If you start to roll backwards, DO NOT applyeither brake abruptly. If you are in 2WD, applyonly the front brake. When this ATV is in 4WD,all wheels (front and rear) are interconnectedby the drive train. This means that applying ei-ther the front brake or the rear will brake allwheels. When descending hills, using eitherbrake lever or the brake pedal will brake thewheels on the downhill side. Avoid sudden ap-plication of either the front or rear brake be-cause the wheels on the uphill side couldcome off the ground. The ATV could easily tipover backwards.

RIDING DOWNHILL When riding your ATV downhill, shift yourweight as far to the rear and uphill side of theATV as possible. Move back on the seat andsit with your arms straight. Engine compres-sion will do most of the braking for you.

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.

Spark plug inspection The spark plug is an important engine compo-nent and is easy to inspect. The condition ofthe spark plug can indicate the condition ofthe engine. For example, a very white center electrodeporcelain color could indicate an intake airleak or carburetion problem for that cylinder.Do not attempt to diagnose such problemsyourself. Instead, take the ATV to a Yamaha dealer.You should periodically remove and inspectthe spark plug because heat and deposits willcause the spark plug to slowly break downand erode. If electrode erosion becomes ex-cessive, you should replace the spark plugwith one of the proper type.

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.
