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.
EBU00538
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 engine is warm, check if it responds to the
throttle normally with the starter (choke) turned
off.
NOTE:
When the parking brake is used, engine speed
is limited to 2,300 r/min. Be sure the parking
brake is released before moving the throttle
lever. Otherwise, the engine will misfire, pre-
venting normal operation.

Shifting
This model has a 6-speed forward transmission.
The transmission allows you to control the
amount of power you have available at a given
speed or for starting, accelerating, climbing hills,
etc. To shift into neutral, return the throttle lever
to its original position, apply the clutch and
repeatedly depress the shift pedal until it stops.
When it stops, it will be in first gear. Raise the
pedal slightly to neutral.

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
direction) 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 obstacles. 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 procedure again. If the riding surface is slip-
pery or loose, it may help to position more of
your weight over the front wheels by moving for-
ward 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 slippery surfaces or rough ter-
rain that may upset your balance.
As you travel across a slope, lean your body in
the uphill direction. It may be necessary to cor-
rect 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
The spark plugs are important engine compo-
nents and are easy to inspect. The condition of
the spark plugs can indicate the condition of the
engine.
Normally, all spark plugs from the same engine
should have the same color on the white porce-
lain insulator around the center electrode. The
ideal color at this point is a medium to light tan
color for a machine that is being ridden normal-
ly. If one spark plug shows a distinctly different
color, there could be something wrong with the
engine.
Do not attempt to diagnose such problems your-
self. Instead, take the machine to a Yamaha
dealer. You should periodically remove and
inspect the spark plugs because heat and
deposits will cause any spark plug to slowly
break down and erode. If electrode erosion
becomes excessive, or if carbon and other
deposits are excessive, you should replace the
spark plug with the specified plug.

You can be burned, or a fire could start if the
bulb touches something flammable.
