tive clothing increases your chances of severe
injury in the event of an accident.

WARNING

EWB01420
Never consume alcohol or drugs before or
while driving this ATV.
Pre-operation checks
Always perform the pre-operation checks listed on
page 5-1 before riding for proper care of the ATV
and to ensure safety.
WARNING

EWB01430
Always inspect your ATV each time you use it
to make sure the ATV is in safe operating con-
dition. Always follow the inspection and main-
tenance procedures and schedules described
in the Owner’s Manual. Failure to inspect the
ATV before operating or failure to properly
maintain the ATV increases the possibility of
an accident or equipment damage.
WARNING

EWB01440
Always use the size and type tires specified in
the Owner’s Manual for this ATV on page 5-4.
Always maintain proper tire pressure as de-
scribed in the Owner’s Manual on page 5-5.Use 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 an accident.
Do not operate at speeds too fast for your
skills or the conditions.WARNING
EWB01450
Always go at a speed that is proper for the ter-
rain, visibility and operating conditions, and
your experience. Operating this ATV at speeds
too fast for your skills or the conditions in-
creases your chances of losing control of the
ATV, which can result in an accident.
Speed limiter
For riders less experienced with this model, the
throttle lever housing is equipped with a speed lim-
iter. The speed limiter keeps the throttle from fully
opening, even when the throttle lever is pushed to
the maximum. Turning in the adjusting screw limits
the maximum engine power available and de-
creases the maximum speed of the ATV. Turning
in the adjusting screw decreases top speed, and
turning it out increases top speed. (See page 4-3.)

This model also has an air intake restrictor plate to
limit the amount of engine power available.
Yamaha recommends that all beginning riders
start off with the speed limiter turned in and the air
intake restrictor plate installed to limit the amount
of speed available while they learn. The limiter may
be gradually adjusted to increase maximum speed
as the beginner becomes more familiar with oper-
ating the ATV. Parents should decide when to ad-
just the ATV for more power as their youngster’s
riding skills improve. Once the ATV rider can oper-
ate with skill at the top speed permitted by adjust-
ing the speed limiter alone, the air intake restrictor
plate can be removed. Since removal of this plate
will result in a significant increase in power, turn
the speed limiter back in again; adjust it out in stag-
es as you did before.
Adjusting for maximum throttle lever movement
without removing the air intake restrictor plate will
cause the engine to run roughly at higher speeds.
For air intake restrictor plate removal instructions,
see page 8-17.
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.

ATV control, which could result in an accident,
including an overturn.
