Troubleshooting

Although Yamaha motorcycles receive
a thorough inspection before shipment
from the factory, trouble may occur
during operation. Any problem in the
fuel, compression, or ignition systems,
for example, can cause poor starting
and loss of power.
The following troubleshooting chart
represents a quick and easy procedure
for checking these vital systems
yourself. However, should your
motorcycle require any repair, take it to
a Yamaha dealer, whose skilled
technicians have the necessary tools,
experience, and know-how to service the
motorcycle properly.
Use only genuine Yamaha replacement
parts. Imitation parts may look like
Yamaha parts, but they are often inferior,
have a shorter service life and can lead
to expensive repair bills.
