Troubleshooting
Although Yamaha machines receive a rigid in-
spection before shipment from the factory,
trouble may occur during operation.
Any problem in the fuel, compression, or igni-
tion 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 genu-
ine 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.
WARNING
Do not smoke when checking the fuel system.
Fuel can ignite or explode, causing severe inju-
ry or property damage. Make sure there are no
open flames or sparks in the area, including pi-lot lights from water heaters or furnaces.

5. Tie a plastic bag over the exhaust pipe
outlet to prevent moisture from entering.
6. If storing in a humid or salt-air atmo-
sphere, coat all exposed metal surfaces
with a light film of oil. Do not apply oil to
any rubber parts or the seat cover.
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 ex-
cessively warm or cold place (less than
0 ˚C or more than 30 ˚C).
NOTE:

Make any necessary repairs before storing the
machine.
