5 Brake fluid leakage (front brake)
Check to see if any brake fluid is leaking out of the
hose, joint or brake fluid reservoir of the front
brake. Apply the brake firmly for one minute. If the
lever moves slowly inward, there may be a leak in
the brake system. If there is any leakage, the brake
system should be checked by a Yamaha dealer.
Brake operation
Test the brakes at slow speed after starting out to
make sure they are working properly. If the brakes
do not provide proper braking performance, check
the brake pads and friction plates for wear. (See
page 8-27.)
WARNING
EWB00580Always check the brakes at the start of every
ride. Do not ride the ATV if you find any prob-
lem with the brakes or you could lose braking
ability, which could lead to an accident. If a
problem cannot be corrected by the adjust-
ment procedures provided in this manual, havea Yamaha dealer check for the cause.
EBU19761Throttle lever Check the operation of the throttle lever. It must
open smoothly and spring back to the idle position
when released. Have a Yamaha dealer correct if
necessary.EBU19811Tires
WARNING
EWB00591Use of improper tires on this ATV, or operation
of this ATV with improper or uneven tire pres-
sure, may cause loss of control, increasing
your risk of accident.
Pay attention to the following.
The tires listed below have been approved
by Yamaha Motor Manufacturing Corpora-
tion of America for this model. Other tire
combinations are not recommended.

The tires should be set to the recommended
pressure:
Recommended tire pressure:
Front:
25.0 kPa (3.6 psi) (0.250 kgf/cm²)
Rear:
25.0 kPa (3.6 psi) (0.250 kgf/cm²)
Check and adjust tire pressures when the
tires are cold.
Tire pressures must be equal on both
sides.
Tire pressure below the minimum speci-
fied could cause the tire to dislodge from
the rim under severe riding conditions.Minimum tire pressure:
Front:
22.0 kPa (3.2 psi) (0.220 kgf/cm²)
Rear:
22.0 kPa (3.2 psi) (0.220 kgf/cm²)
Use no more than the following pressures
when seating the tire beads.
Maximum tire seating pressure:
Front:
250 kPa (36 psi) (2.5 kgf/cm²)
Rear:
250 kPa (36 psi) (2.5 kgf/cm²)
Higher pressures and fast inflation may
cause a tire to burst. Inflate the tires very
slowly and carefully.EBU19820Measuring the tire pressure Use the low-pressure tire gauge.NOTE:The low-pressure tire gauge is included as stan-
dard equipment. Make two measurements of the
tire pressure and use the second reading. Dust or
dirt in the gauge could cause the first reading to beincorrect.
