Speed limiter
The speed limiter keeps the throttle from fully
opening, even when the throttle lever is pushed to
the maximum. Screwing in the adjuster limits the
maximum engine power available and decreases
the maximum speed of the ATV.
WARNING
Improper adjustment of the speed limiter and
throttle could cause throttle cable damage or
improper throttle operation. You could lose
control, have an accident or be injured. Do not
turn the speed adjuster out more than 12 mm
or the throttle cable could be damaged. Always
make sure the throttle lever free play is adjust-
ed to 3–5 mm. See page 8-41.

a collision.


Always be sure you have released the
parking brake before you begin to ride. The
brake could overheat if you ride the ATV
without releasing the parking brake. You
could lose braking performance which
could cause an accident. You could also
wear out the brakes prematurely.

Parking on a slope
WARNING
Avoid parking on hills or other inclines. Park-
ing on a hill or other incline could cause the
ATV to roll out of control, increasing the
chance of an accident. If you must park on an

parking brake, and block the front and rear
wheels with rocks or other objects.
Do not park the ATV at all on hills that are so
steep you could not walk up them easily.1. Bring the machine to a stop by applying the
brakes in low gear.
2. Stop the engine.

apply the parking brake and slowly release
the rear brake pedal.

Speed limiter
For riders inexperienced with this model, this mod-
el is equipped with a speed limiter in the throttle le-
ver housing. The speed limiter limits the power
and top speed of the ATV. Turning the screw in de-
creases top speed, and turning it out increases top
speed.
Loading and accessories
Use extra caution when riding the ATV with addi-
tional loads, such as accessories or cargo. The
ATV’s handling may be adversely affected. Re-
duce your speed when adding additional loads.
