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.
