EBU01051Speed 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.
Your ATV was delivered with an adjustable
speed limiter and also with an air intake restric-
tor plate. Yamaha recommends that all begin-
ners start off with the speed limiter screw turned
in and the air intake restrictor plate installed to
limit the amount of speed available while they
learn. The limiter screw may be gradually turned
out to increase maximum speed as the beginner
becomes more familiar with operating the ATV.
Parents should decide when to adjust the ATV
for more power as their youngster’s riding skills
improve. Once the ATV rider can operate with
skill at the top speed permitted by adjusting the
speed limiter alone, the air intake restrictor plate
can be removed.

EBU00075Parking brake
Use the parking brake when you have to start
the engine or park the machine, especially on a
slope. Apply the rear brake lever and push down
the lock plate to apply the parking brake.
Squeeze the rear brake lever to release the
parking brake.w8Always 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 con-
trol or a collision.
8Always 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.

EBU00220Parking on a slopewAvoid parking on hills or other inclines.
Parking 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 incline, put the machine in low gear, apply
the 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.
3. With the rear brake lever and pedal
applied, apply the parking brake and slowly
release the rear brake pedal.

Speed limiter
For riders inexperienced with this model, this model
is equipped with a speed limiter in the throttle lever
housing. The speed limiter limits the power and top
speed of the ATV. Turning the screw in decreases
top speed, and turning it out increases top speed.
This model also has an air intake restrictor plate to
limit the amount of engine power available.
Yamaha recommends that all beginners 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 grad-
ually adjusted to increase maximum speed as the
beginner becomes more familiar with operating the
ATV. Parents should decide when to adjust the
ATV for more power as their youngster’s riding
skills improve. Once the ATV rider can operate with
skill at the top speed permitted by adjusting 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 completely back in again; adjust it out
in stages 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.

wUse proper gear and maintain steady speed
when climbing a hill.
If you lose all forward speed:
8Keep weight uphill.
8Apply the brakes.
8Lock the parking brake, after you are
stopped.
If you begin rolling backwards:
8Keep weight uphill.
8Never apply the rear brake while rolling
backwards. Apply the front brake.
When fully stopped, apply the rear brake
as well, and then lock the parking brake.
Dismount on uphill side or to a side if point-
ed straight uphill. Turn the ATV around and
remount, following the procedure described
in the Owner’s Manual.
