MAINTENANCE
TIRE MAINTENANCE
This dirt bike is equipped with low pressure tires of the size
and type listed below:
Front Rear
Size 60/100-14 80/100-12
Tire Air Pressure
Check the air pressure in all tires before riding. Improper air
pressure will affect handling, steering response, traction, tire
life and rider comfort. Be sure tires are inflated to the pres-
sures shown below.
NOTE: Tire pressure should only be measured or
adjusted when tires are cold.
Recommended Pressure
15-18 psi (103-124 kPa)
WARNING:
Check the tire pressure carefully while inflating. Too much
air in the tire could cause the tire to burst, causing serious
personal injury.
WARNING:
Maintaining correct air pressure in the tires is very impor-
tant. Too little pressure could allow the tire to rotate off
the wheel rim. Too much pressure could cause the tire to
burst. Failure to maintain correct air pressure in the tires
could cause problems with vehicle operation and stability,
causing serious personal injury.
TIRE REPAIR
If a leak or flat tire occurs due to a puncture, tire and tube
will need to be replaced.
REPLACING TIRES
When tires are worn, the traction of the vehicle will be
decreased, which increases the chance of having an acci-
dent. Tires should be replaced when the depth on the tread
is 0.16 in. (4 mm) or less. Always use the tire type and size
recommended in this operator’s manual. Using improper tires
on the unit could cause loss of control, which could increase
your risk of accident.
Have tires replaced by an authorized service center or a
qualified tire repair station.
CLEANING
A thorough cleaning of the dirt bike is a necessary part of
maintenance. It will help keep the dirt bike looking and per-
forming at its best. Proper cleaning can also extend the life
of the dirt bike.
Clean and inspect the dirt bike after every ride, especially
if it is used in mud, brush, grass, water, salt water, or very
dusty conditions. The build-up of mud, brush, grass, etc.,
especially on the engine and exhaust system, can reduce
engine cooling ability, conceal damage, or increase wear of
certain parts. Remove all debris during cleaning.
The dirt bike should be washed before any mud dries on the
unit. Avoid spraying or allowing water to flow over the igni-
tion switch, spark plug, fuel tank cap, carburetor, or air filter.
NOTE: Do not use high pressure washers such as those
found at car washes. They could cause mechanical, electri-
cal and other damage.

Hand wash the unit with mild soap or detergent and wa-
ter. Try to thoroughly remove all dirt and debris without
excessive water pressure. Cloth rags, washing mitts, or
cleaning brushes can be used, but be careful with brushes
as they can scratch plastic or painted surfaces.
 Rinse the unit thoroughly with clean water.
 Dry all areas using a chamois or soft absorbent cloth or
allow the unit to air dry.
 Lubricate the chain and run the engine at idling speed for
a few minutes.
 Follow the procedures in Pre-Ride Inspection to check
the unit for any problems that may have occurred during
your last ride.
 After washing your dirt bike, test your brakes by riding at
a slow speed. If necessary, apply brake several times to
let the friction dry out the brake linings. Wet brakes may
not provide as much stopping power as dry brakes.
WARNING:
Operating the dirt bike at high speeds when the brakes
are wet could result in serious personal injury.
