Troubleshooting
Although Yamaha vehicles receive a rigid inspec-
tion 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 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
Do not smoke when checking the fuel system.
Fuel can ignite or explode, causing severe in-
jury or property damage. Make sure there are
no open flames or sparks in the area, including
pilot lights from water heaters or furnaces.

ATTENTION:
Ne pas mélanger d’additif chimique à l’huile afin d’éviter
tout patinage de l’embrayage, car l’huile moteur lubrifie
également l’embrayage. Ne pas utiliser d’huile de grade die-
sel “CD” ou une huile de grade supérieur à celui spécifié.
S’assurer également de ne pas utiliser une huile portant la
désignation “ENERGY CONSERVING II” ou la même dé-
signation avec un numéro plus élevé.
