After riding your ATV in water, be sure to drain the
trapped water by removing the check hose at the
bottom of the air filter case.
NOTICE:
Undrained
water can cause damage or improper opera-
tion.
[ECB00841]

Wash the ATV in fresh water if it has been operat-
ed in salt water or muddy conditions.
RIDING OVER ROUGH TERRAIN
WARNING
EWB01651
Riding improperly over obstacles could cause
loss of control or a collision. Before operating
in a new area, check for obstacles. Never at-
tempt to ride over large obstacles, such as
large rocks or fallen trees. When you go over
obstacles, always follow proper procedures as
described in the Owner’s Manual.
Riding over rough terrain should be done with cau-
tion. Look out for obstacles which could cause

coolant until it reaches the top of the radiator,
and then install the radiator cap.
14. Start the engine, and then check for coolant
leakage.
TIP

If any leakage is found, have a Yamaha dealer
check the cooling system.
15. Install the radiator cover by installing the
screws.

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 or, if necessary, replace
the air filter element more frequently if you are
riding in unusually wet or dusty areas.
TIP

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. Place the ATV on a level surface.
2. Remove the seat. (See page 4-11.)
3. Remove the air filter case cover by unhooking
the holders.

6. Wash the sponge material gently but thor-
oughly in solvent.
WARNING! Always use
parts cleaning solvent to clean the sponge
material. Never use low-flash-point sol-
vents or gasoline to clean the sponge ma-
terial because the engine could catch fire
or explode.
[EWB01941]

7. Squeeze the excess solvent out of the sponge
material and let it dry.
NOTICE:
Do not twist
the sponge material when squeezing
it.
[ECB00441]
8. Check the sponge material and replace it if
damaged.
9. Apply Yamaha foam air filter oil or other qual-
ity foam air filter oil to the sponge material.
TIP

The sponge material should be wet but not drip-
ping.
10. Pull the sponge material over the air filter ele-
ment frame, and then install the lock plate by
turning it.

11. Insert the air filter element into the air filter
case, and then install the air filter case cover
by hooking the holders onto the air filter case.
NOTICE:
Make sure that the air filter ele-
ment is properly seated in the air filter
case. Never operate the engine with the air
filter element removed. This will allow un-
filtered air to enter the engine, causing rap-
id engine wear and possible engine
damage. Additionally, operation without
the air filter element will affect carburetor
jetting with subsequent poor performanceand possible engine overheating.
[ECB00461]

12. Install the seat.TIP

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 areas. Each time the air filter element main-
tenance is performed, check the air inlet of the air
filter case for obstructions. Check the air filter case
rubber joint to the carburetor fittings and the rubber
joint manifold fittings for an air-tight seal. Tighten
all fittings securely to avoid the possibility of unfil-
tered air entering the engine.

fore cleaning the spark arrester.

The engine idling speed must be checked and, if
necessary, adjusted as follows at the intervals
specified in the periodic maintenance and lubrica-tion chart.TIP

adjustment.

The carburetor synchronization and the throttle
cable free play must be checked, and adjusted if
necessary, before adjusting the engine idling
speed.
1. Start the engine and warm it up.
TIP

The engine is warm when it quickly responds to the
throttle.
2. Attach the tachometer to the spark plug lead.
3. Turn in both pilot air screws until they lightly
seat.
