PERIODIC MAINTENANCE AND ADJUSTMENT
Periodic inspection, adjustment, and lubrication will keep your vehicle 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.
EWB01842
WARNING
Failure to properly maintain the vehicle or performing maintenance activities incorrectly may increase your risk of injury or death during service or while using the vehicle. If you are not familiar with vehicle service, have a Yamaha dealer perform the service.
EWB02563
WARNING
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 electrical parts that can cause shocks or fires.
Running the engine while servicing can lead to eye injury, burns, fire, or carbon monoxide poisoning - possibly leading to death. See
page 2-6 for more information about carbon
monoxide.
EWB02691
WARNING
Brake discs, calipers, drums, and linings can become very hot during use. To avoid possible burns, let brake components cool before touching them.
The intervals given in the periodic maintenance charts should be considered as a general guide under normal riding conditions. However, DE-
PENDING ON THE WEATHER, TERRAIN, GEO-
GRAPHICAL LOCATION, AND INDIVIDUAL USE,
THE MAINTENANCE INTERVALS MAY NEED TO
BE SHORTENED.

Checking the spark plug
The spark plug is an important engine component, which is easy to check. Since heat and deposits will cause any spark plug to slowly erode, the spark plug should be removed and checked in accordance with the periodic maintenance and lubrication chart. In addition, the condition of the spark plug can reveal the condition of the engine.
To remove the spark plug
1. Remove panels A and C. (See page 8-9.)
2. Remove the storage compartment by removing the bolt.

To check the spark plug
1. Check that the porcelain insulator around the center electrode of the spark plug is a medium-to-light tan (the ideal color when the vehicle is ridden normally).
TIP
If the spark plug shows a distinctly different color, the engine could be operating improperly. Do not attempt to diagnose such problems yourself. Instead, have a Yamaha dealer check the vehicle.
2. Check the spark plug for electrode erosion and excessive carbon or other deposits, and replace it if necessary.
Specified spark plug:
NGK/CPR7EA-9
3. Measure the spark plug gap with a wire thickness gauge and, if necessary, adjust the gap to specification.

1. Spark plug gap
Spark plug gap:
0.8–0.9 mm (0.031–0.035 in)
To install the spark plug
1. Clean the surface of the spark plug gasket and its mating surface, and then wipe off any grime from the spark plug threads.
2. Install the spark plug with the spark plug wrench, and then tighten it to the specified torque.
Tightening torque:
Spark plug:
11 N·m (1.1 kgf·m, 8.0 lb·ft)
TIP
If a torque wrench is not available when installing the spark plug, a good estimate of the correct torque is 1/4–1/2 turn past finger tight. However, the spark plug should be tightened to the specified torque as soon as possible.
3. Install the spark plug cap.

Insufficient brake fluid may allow air to enter the brake system, reducing braking performance.
Clean the filler cap before removing. Use only DOT 4 brake fluid from a sealed container.
Use only the specified brake fluid; otherwise, the rubber seals may deteriorate, causing leakage.
Refill with the same type of brake fluid. Adding a brake fluid other than DOT 4 may result in a harmful chemical reaction.
Be careful that water does not enter the brake fluid reservoir when refilling. Water will significantly lower the boiling point of the fluid and may result in vapor lock.
ECB01161
NOTICE
Brake fluid may damage painted surfaces or plastic parts. Always clean up spilled fluid immediately.
As the brake pads wear, it is normal for the brake fluid level to gradually go down. A low brake fluid level may indicate worn brake pads and/or brake system leakage; therefore, be sure to check the

Troubleshooting
Although Yamaha ATVs receive a thorough inspection before shipment from the factory, trouble may occur during operation. Any problem in the fuel, compression, or ignition systems, for example, can cause poor starting and loss of power.
The following troubleshooting charts represent quick and easy procedures for checking these vital systems yourself. However, should your ATV require any repair, take it to a Yamaha dealer, whose skilled technicians have the necessary tools, experience, and know-how to service the
ATV properly.
Use only genuine Yamaha replacement parts. Imitation parts may look like Yamaha parts, but they are often inferior, have a shorter service life and can lead to expensive repair bills.
EWB02281
WARNING
Do not smoke when checking the fuel system.
Fuel can ignite or explode, causing severe injury or property damage. Make sure there are no open flames or sparks in the area, including pilot lights from water heaters or furnaces.
