NOTE:


The air filter needs more frequent service if you are riding in unusually wet or dusty areas.

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.

EBU23211
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 accor-
dance with the periodic maintenance and lubrica-
tion chart. In addition, the condition of the spark
plug can reveal the condition of the engine.
To remove the 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 plug
1. Check that the porcelain insulator around the
center electrode of the spark plug is a medi-
um-to-light tan (the ideal color when the ATV
is ridden normally).
NOTE:

If the 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.

2. Check the spark plug for electrode erosion
and excessive carbon or other deposits, and
replace it if necessary.
To install the spark plug
1. Measure the spark plug gap with a wire thick-
ness gauge and, if necessary, adjust the gap
to specification.2. Clean the surface of the spark plug gasket
and its mating surface, and then wipe off any
grime from the spark plug threads.
3. Install the spark plug with the spark plug
wrench, and then tighten it to the specified
torque.NOTE:

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.
4. Install the spark plug cap.

Transmission oil
The transmission oil level should be checked be-
fore each ride. In addition, the transmission oil
must be changed at the intervals specified in the
periodic maintenance and lubrication chart. Specified spark plug:
NGK/BR8ES
Spark plug gap:
0.7–0.8 mm (0.028–0.031 in)
1. Spark plug gap
Tightening torque:
Spark plug:

To check the transmission oil level
1. Place the ATV on a level surface.
2. Start the engine, warm it up for several min-
utes, and then turn it off.
3. Wait a few minutes until the oil settles, and
then check the oil level through the check win-
dow located at the right side of the crankcase.NOTE:

The transmission oil should be between the mini-
mum and maximum level marks.
4. If the oil is at or below the minimum level mark,
remove the oil filler cap, add sufficient oil of
the recommended type to raise it to the cor-
rect level, and then install and tighten the oil
filler cap.
To change the transmission oil
1. Place the ATV on a level surface.
2. Start the engine, warm it up for several min-
utes, and then turn it off.

3. Place an oil pan under the transmission to col-
lect the used oil.
4. Remove the oil filler cap and the drain bolt to
drain the oil from the transmission.
5. Install the drain bolt, and then tighten it to the
specified torque.
6. Add the specified amount of the recommend-
ed transmission oil, and then install and tight-en the oil filler cap.CAUTION:
ECB00430

In order to prevent clutch slippage (since the
transmission oil also lubricates the clutch),
do not mix any chemical additives. Do not
use oils with a diesel specification of “CD” or
oils of a higher quality than specified. In ad-
dition, do not use oils labeled “ENERGY
CONSERVING II” or higher.

Make sure that no foreign material enters the
crankcase.
7. Start the engine, and then let it idle for several
minutes while checking the transmission for
oil leakage. If oil is leaking, immediately turn
off the engine and check for the cause.
8. Turn the engine off, and then check the oil lev-
el and correct it if necessary.

Autolube pump
The Autolube pump is a vital part of the engine and
requires very sophisticated adjustment. The Autol-
ube pump should be checked and, if necessary,
adjusted at the intervals specified in the periodic
maintenance and lubrication chart. Any adjusting
should be left to a Yamaha dealer who has the pro-
fessional knowledge and experience to do so.
EBU23781
Cleaning the air filter element
The air filter element should be cleaned at the in-
tervals specified in the periodic maintenance and
lubrication chart. Clean the air filter element more
frequently if you are riding in unusually wet or dusty
areas.
NOTE:

There is a check hose at the bottom of the air filter
case. If dust or water collects in this hose, empty
the hose and clean the air filter element and air fil-
ter case.1. Remove the seat. (See page 4-11.)
2. Remove the air filter case cover by removing
the screws.

oughly in solvent.
WARNING
EWB01940
Always use parts cleaning solvent to clean the
sponge material. Never use low-flash-point
solvents or gasoline to clean the sponge mate-
rial because the engine could catch fire or ex-
plode.
7. Squeeze the excess solvent out of the sponge
material and let it dry.
