Troubleshooting

Although Yamaha motorcycles receive

a thorough inspection before shipment

from the factory, trouble may occur dur-

ing 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 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 replace-

ment parts. Imitation parts may look like

Yamaha parts, but they are often inferi-

or, have a shorter service life and can

lead to expensive repair bills.

WARNING

EWA15141

When checking the fuel system, do

not smoke, and make sure there are

no open flames or sparks in the ar-

ea, including pilot lights from water

heaters or furnaces. Gasoline or

gasoline vapors can ignite or ex-

plode, causing severe injury or

property damage.
