Troubleshooting
Although Yamaha machines receive a rigid
inspection 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 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 gen-
uine 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.

contain anti-friction additives which will cause
clutch and/or starter clutch slippage, resulting
in reduced component life and poor engine
performance.

Veiller à ce que l’huile de moteur utilisée ne
contienne pas d’additifs antifriction. Les huiles
pour voitures (portant souvant la désignation
“ENERGY CONSERVING
II”) contiennent des
additifs antifriction qui vont faire patiner
l’embrayage et/ou l’embrayage de démarreur, ce
qui va provoquer une réduction de la durabilité
des organes et une baisse de rendement.
