Carburetor settings
In extremely cold weather, it is necessary to
change the carburetor settings to maintain opti-
mum engine performance and to prevent engine
damage.
w
8Improperly servicing or adjusting the car-
buretor could cause malfunction with the
possibility of an accident or the carburetor
could leak fuel, which would be a fire haz-
ard.
8Carburetor adjustments should only be
performed by a Yamaha dealer. Do not
attempt to perform these procedures
unless you have mechanical knowledge
and the necessary tools.
8Do not perform this procedure while the
engine is hot. Place a rag under the carbu-
retor to catch any fuel. Wipe up any spilled
fuel completely.
8After servicing the carburetor, always
check throttle operation before operating
the ATV to make sure it is working correct-
ly.

Troubleshooting
Although Yamaha machines receive a rigid
inspection before shipment from the factory,
trouble may occur during operation.
Any problem in the fuel, compression, or ignition
systems can cause poor starting and loss of
power. The troubleshooting chart describes a
quick, easy procedure for making checks. If
your machine requires any repair, take it to a
Yamaha dealer.
The skilled technicians at a Yamaha dealership
have the tools, experience, and know-how to
properly service your machine. Use only gen-
uine Yamaha parts on your machine. Imitation
parts may look like Yamaha parts, but they are
often inferior. Consequently, they have a short-
er service life and can lead to expensive repair
bills.

Do not smoke when checking the fuel sys-
tem. Fuel can ignite or explode, causing
severe injury or property damage. Make sure
there are no open flames or sparks in the
area, including pilot lights from water
heaters or furnaces.

B. STORAGE
Long term storage (60 days or more) of your
machine will require some preventive proce-
dures to guard against deterioration. After thor-
oughly cleaning the machine, prepare for stor-
age as follows:
1. Fill the fuel tank with fresh fuel and add fuel
stabilizer (if available).
NOTE:
Use of fuel stabilizer eliminates the need to
drain the fuel system. Consult a Yamaha dealer
if the fuel system is to be drained instead.
2. Remove the spark plug, pour about one
tablespoon of SAE 10W30 or 20W40 motor
oil in the spark plug hole and reinstall the
spark plug. Ground the spark plug wire and
turn the engine over several times to coat
the cylinder wall with oil.
3. Clean the drive chain thoroughly and lubri-
cate it. (See page 8-77.)
