Troubleshooting
Although Yamaha vehicles receive an inspection
before shipment from the factory, trouble may oc-
cur during operation. Any problem in the fuel, com-
pression, or ignition systems can cause poor
starting and loss of power. The troubleshooting
chart describes a quick, easy procedure for mak-
ing checks. If your vehicle requires any repair, take
it to a Yamaha dealer.
The skilled technicians at a Yamaha dealership
have the tools, experience, and know-how to prop-
erly service your vehicle. Use only genuine
Yamaha parts on your vehicle. Imitation parts may
look like Yamaha parts, but they are often inferior.
Consequently, they have a shorter service life and
can lead to expensive repair bills.
WARNING
When checking the fuel system, do not smoke
and make sure there are no open flames or
sparks in the area, including pilot lights from
water heaters or furnaces. Gasoline or gaso-
line vapors can ignite or explode, causing se-
vere injury or property damage.

B. Storage
Long term storage (60 days or more) of your vehi-
cle will require some preventive procedures to
guard against deterioration. Make any necessary
repairs before storing the vehicle.
After thoroughly cleaning the vehicle, prepare for
storage as follows:
1. Fill the fuel tank with fresh fuel and add the
specified amount of Yamaha Fuel Stabilizer
and Conditioner or equivalent product. Oper-
ate the vehicle for at least 5 minutes to dis-
tribute treated fuel through the fuel system.
2. Remove the spark plug, pour a teaspoonful
of engine oil into the spark plug bore and re-
install the spark plug. Ground the spark plug
wire and turn the engine over several times to
coat the cylinder wall with oil. Specified amount:
1 oz of stabilizer to each gallon of fuel
(or 7.5 ml of stabilizer to each liter of fuel)

3. Lubricate all control cables.
4. Block up the frame to raise all wheels off the
ground.
5. Tie a plastic bag over the exhaust pipe outlet
to prevent moisture from entering.
6. If storing in a humid or salt-air atmosphere,
coat all exposed metal surfaces with a light
film of oil. Do not apply oil to any rubber parts
or the seat covers.
7. Remove the battery and charge it. Store it in
a dry place and recharge it once a month. Do
not store the battery in an excessively warm
or cold place [less than 0°C (30°F) or more
than 30°C (90°F)].
Use of fuel stabilizer and conditioner eliminates
the need to drain the fuel system. Consult a
Yamaha dealer if the fuel system needs to be
drained.

The figures quoted are emission levels and are not
necessarily safe working levels. Whilst there is a
correlation between the emission and exposure
levels, this cannot be used reliably to determine
whether or not further precautions are required.
Factors that influence the actual level of exposure
of work-force include the characteristics of the
work room, the other sources of noise, etc. i.e. the
number of machines and other adjacent process-
es, and the length of time for which an operator is
exposed to the noise. Also the permissible expo-
sure level can vary from country. This information,
however, will enable the user of the machine to
make a better evaluation of the hazard and risk.
