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 8-55.

WARNING


Always set the parking brake before start-
ing the engine. The ATV could start mov-
ing unexpectedly if the parking brake is not
applied. This could cause loss of control or
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.

Rear shock absorber adjustment
The spring preload, rebound damping and com-
pression damping forces of the rear shock absorb-
er can be adjusted to suit the rider’s weight and the
riding conditions.
WARNING
_ This shock absorber contains highly pressur-
ized nitrogen gas. Read and understand the
following information before handling the
shock absorber.

Do not tamper with or attempt to open the
cylinder assembly.


Do not subject the shock absorber to an
open flame or other high heat source. This

CAUTION:_ Never turn an adjusting mechanism beyond
the minimum and maximum settings. _NOTE:_ Although the total number of clicks of a damping
force adjusting mechanism may not exactly match
the above specifications due to small differences in
production, the actual number of clicks always repre-
sents the entire adjusting range. To obtain a precise
adjustment, it would be advisable to check the num-
ber of clicks of each damping force adjusting mech-
anism and to modify the specifications as necessary. _
WARNING
_ Suspension components become hot during
operation. Never touch the compression
damping adjuster, rebound damping adjuster
or oil reservoir with your bare hand or skin un-
til suspension components have cooled. _

Brake fluid leakage

Check to see if any brake fluid is leaking out of
the pipe joints or master cylinders. Apply the
brakes firmly for one minute. If there is any
leakage, have the machine inspected 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 perfor-
mance, inspect the brake pads for wear. (See
page 8-59.)WARNING
_ Always check the brakes at the start of every
ride. Do not ride the ATV if you find any prob-

WARNING
_

Do not overfill the fuel tank. Fuel expands
when it heats up. If the fuel tank is over-
filled, fuel could spill out due to heat from
the engine or the sun.


Be careful not to spill fuel, especially on
the engine or exhaust pipe which can
cause a fire and severe injury. Wipe up any
spilled fuel immediately.


Do not refuel right after the engine has
been running and is still very hot.


Be sure the fuel tank cap is closed secure-
ly.
