riding techniques completely.
WHAT TO DO...
●If your ATV doesn’t turn when you want it
to:
Bring the ATV to a stop and practice the
turning maneuvers again. Be sure you are
putting your weight on the footboard to the
outside of the turn. Position your weight
over the front wheels for better control.
(See pages 7-39 ~ 7-43.)
●If your ATV begins to tip while turning:
Lean more into the turn to regain balance. If
necessary, gradually let off the throttle
and/or steer to the outside of the turn. (See
pages 7-39 ~ 7-43.)
●If your ATV starts to slide sideways:
Steer in the direction of the slide if you have
the room.
Applying the brakes or accelerating is not
recommended until you have corrected the
slide. (See pages 7-69 ~ 7-71.)

Front brake pad inspection
Inspect the brake pads for damage and wear. If
the thickness is less than the specified value,
have a Yamaha dealer replace the pads.
NOTE:
The wheels need to be removed to inspect the
brake pads. See page 8-71 for removal proce-
dures.
EBU00313
Rear brake shoe inspection
A wear indicator is provided on the rear brake.
This indicator allows checking of brake shoe
wear without disassembling the brake.
Apply the rear brake and check the position of
the indicator. If the indicator reaches the wear
limit line, ask a Yamaha dealer to replace
shoes as a set.

CLEANING AND STORAGE
A. CLEANING
Frequent, thorough cleaning of your machine
will not only enhance its appearance but will
improve its general performance and extend
the useful life of many components.
1. Before cleaning the machine:
a. Block off the end of the exhaust pipe to
prevent water entry. A plastic bag and
strong rubber band may be used.
b. Make sure the spark plug and all filler caps
are properly installed.
2. If the engine case is excessively greasy,
apply degreaser with a paint brush. Do
not apply degreaser to the wheel axles.
3. Rinse the dirt and degreaser off with a
garden hose. Use only enough pressure
to do the job.

9-3
CAUTION:
Excessive water pressure may cause water
seepage and deterioration of wheel bearings,
brakes, transmission seals and electrical de-
vices. Many expensive repair bills have result-
ed from improper high pressure detergent
applications such as those available in coin-
operated car washers.
4. Once the majority of the dirt has been
hosed off, wash all surfaces with warm
water and mild, detergent-type soap. An
old toothbrush or bottle brush is handy
for hard-to-get-at places.
5. Rinse the machine off immediately with
clean water and dry all surfaces with a
chamois, clean towel or soft absorbent
cloth.
6. Clean the seat with a vinyl upholstery
cleaner to keep the cover pliable and
glossy.

B. STORAGE
Long term storage (60 days or more) of your
machine will require some preventive proce-
dures to guard against deterioration. After
thoroughly cleaning the machine, prepare for
storage as follows:
1. Fill the fuel tank with fresh fuel and add
fuel stabilizer (if available).
NOTE:
Use of fuel stabilizer eliminates the need to
drain the fuel system. Consult a Yamaha dealer
if the fuel system is to be drained instead.
2. Remove the spark plug, pour about one
tablespoon of SAE 10W30 or 20W40 mo-
tor oil in the spark plug hole and reinstall
the spark plug. Ground the spark plug
wire and turn the engine over several
times to coat the cylinder wall with oil.
3. Lubricate all control cables.
4. Block up the frame to raise all wheels off
the ground.
