Trou bleshootin gAlthough your Yamaha received a thor-
ough 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 your-
self. However, should your vehicle re-
quire any repair, take it to an
authorized Yamaha dealer whose
skilled technicians have the necessary
tools, experience, and know-how to
properly service your Yamaha vehicle.
Be sure to use only genuine Yamaha
replacement parts. Although imitation
parts may look similar to genuine parts,
they are often inferior in quality, have a
shorter service life, and can lead to an
expensive repair bill later on.
