TIP


Some maintenance items need more frequent service if you are riding in unusually wet, dusty, sandy or
muddy areas, or at full-throttle.

Hydraulic brake service

Regularly check and, if necessary, correct the brake fluid level.

Every two years replace the internal components of the brake master cylinders and calipers, and
change the brake fluid.

Replace the brake hoses every four years and if cracked or damaged.

EBU28321
Checking the spark plugs
The spark plugs are important engine compo-
nents, which are easy to check. Since heat and de-
posits will cause any spark plug to slowly erode,
the spark plugs should be removed and checked in
accordance with the periodic maintenance and lu-
brication chart. In addition, the condition of the
spark plugs can reveal the condition of the engine.
To remove a spark plug
1. Remove the spark plug cap.
2. Remove the spark plug as shown, with thespark plug wrench included in the owner’s tool
kit.
To check the spark plugs
1. Check that the porcelain insulator around the
center electrode of each spark plug is a medi-
um-to-light tan (the ideal color when the ATV
is ridden normally).
2. Check that all spark plugs installed in the en-
gine have the same color.TIP

If any spark plug shows a distinctly different color,
the engine could be operating improperly. Do not

attempt to diagnose such problems yourself. In-
stead, have a Yamaha dealer check the ATV.
3. Check each spark plug for electrode erosion
and excessive carbon or other deposits, and
replace it if necessary.
4. Measure the spark plug gap with a wire thick-
ness gauge and, if necessary, adjust the gap
to specification.
To install a 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.TIP

If a torque wrench is not available when installing
a 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.
