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.

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.
