ommended to shift into neutral or park before
starting the engine.

Starting a warm engine
To start a warm engine, refer to the “Starting a cold
engine” section. The starter (choke) should not be
used. The throttle should be opened slightly.
EBU00182
Warming up
To get maximum engine life, always warm up the
engine before starting off. Never accelerate hard
with a cold engine! To see whether or not the en-
gine is warm, check if it responds to the throttle
normally with the starter (choke) turned off.

Shifting: Neutral to Reverse and Reverse to
ParkNOTE:The drive select lever cannot be shifted into or
from reverse or park without applying the rear
brake. 1. Bring the machine to a complete stop and re-
turn the throttle lever to the closed position.
2. Apply the rear brake pedal.
3. Shift from neutral to reverse or from reverse
to park and vice versa by moving the drive
select lever along the shift guide.NOTE:

When in reverse, the reverse indicator light
should be on. If the light does not come on,
ask a Yamaha dealer to inspect the reverse in-
dicator light electrical circuit.


Due to the synchronizing mechanism in the
engine, the light may not come on until the
ATV starts moving.

7-41 1. Lean towards inside of turn.
2. Support your weight on the outer footboard.
1. Se pencher vers l’intérieur du virage.
2. S’appuyer sur le repose-pied extérieur.
1. Inclínese hacia el interior del giro.
2. Descanse su peso en el descansapie exterior.
As you approach a curve, slow down and begin to
turn the handlebars in the desired direction. As
you do so, put your weight on the footboard to the
outside of the turn (opposite your desired direc-
tion) and lean your upper body into the turn. Use
the throttle to maintain an even speed through the
turn. This maneuver will let the wheel on the inside
of the turn slip slightly, allowing the ATV to make
the turn properly.
This procedure should be practiced at slow speed
many times in a large off-road area with no obsta-
cles. If an incorrect technique is used, your ATV
may continue to go straight. If the ATV doesn’t
turn, come to a stop and then practice the proce-
dure again. If the riding surface is slippery or loose,
it may help to position more of your weight over the
front wheels by moving forward on the seat.
Once you have learned this technique you should
be able to perform it at higher speeds or in tighter
curves.

CROSSING A SLOPE
Traversing a sloping surface on your ATV requires
you to properly position your weight to maintain
proper balance. Be sure that you have learned the
basic riding skills on flat ground before attempting
to cross a sloping surface. Avoid slopes with slip-
pery surfaces or rough terrain that may upset your
balance.
As you travel across a slope, lean your body in the
uphill direction. It may be necessary to correct the
steering when riding on loose surfaces by pointing
the front wheels slightly uphill. When riding on
slopes be sure not to make sharp turns either up or
down hill.

Spark plug inspection
Removal
1. Remove panel A. (See page 8-17 for panel
removal and installation procedures.)
2. Remove the spark plug cap.
3. Use the spark plug wrench in the tool kit to re-
move the spark plug as shown.
Inspection
The spark plug is an important engine component
and is easy to inspect. The condition of the spark
plug can indicate the condition of the engine.
The ideal color on the white insulator around the
center electrode is a medium-to-light tan color for a
ATV that is being ridden normally.
