3. Remove the final gear oil filler cap and the fi-
nal gear oil drain bolt to drain the oil from the
final gear case.
4. Install the drain bolt, and then tighten it to the
specified torque.
5. Add the specified amount of the recommend-ed final gear oil, and then check the oil level.CAUTION:
ECB00420
Be sure no foreign material enters the final
gear case.
6. Install and tighten the oil filler cap.
7. Check the final gear case for oil leakage. If oil
is leaking, check for the cause.

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-

CAUTION:

ECB00440
Do not twist the sponge material when squeez-
ing it.
6. Check the sponge material and replace it if
damaged.
7. Apply a quality foam air filter oil to the sponge
material.
NOTE:

The sponge material should be wet but not drip-
ping.
8. Install the sponge material into the air filter el-
ement.
9. Place the air filter element in the original posi-
tion, and then hook the holder.
10. Install the air filter case cover by hooking the
holders onto the air filter case.
11. Install the panel by installing the bolts.
NOTE:

The air filter element should be cleaned every 20–
40 hours. It should be cleaned and lubricated more
often if the ATV is operated in extremely dusty ar-
eas. Each time the air filter element maintenance
is performed, check the air inlet of the air filter case
for obstructions.
CAUTION:

ECB00460

Make sure that the air filter element is prop-
erly seated in the air filter case.

Never operate the engine with the air filter el-
ement removed. This will allow unfiltered air
to enter the engine, causing rapid engine
wear and possible engine damage. Addition-
ally, operation without the air filter element
will affect carburetor jetting with subsequent
poor performance and possible engine over-
heating.

Removing the air intake restrictor plate
To obtain full engine performance capability, re-
moving the air intake restrictor plate is required.
1. Remove the air filter element. (See
page 8-12.)
2. Remove the air intake restrictor plate.
