Troubleshooting

Although Yamaha ATVs receive a thorough in-
1
spection before shipment from the factory, trouble
2
may occur during operation. Any problem in the fu-
el, compression, or ignition systems, for example,
3
can cause poor starting and loss of power.
The following troubleshooting chart represents a
4
quick and easy procedure for checking these vital
systems yourself. However, should your ATV re-
5
quire any repair, take it to a Yamaha dealer, whose
skilled technicians have the necessary tools, expe-
6
rience, and know-how to service the ATV properly.
Use only genuine Yamaha replacement parts. Im-
7
itation parts may look like Yamaha parts, but they
are often inferior, have a shorter service life and
8
can lead to expensive repair bills.

WARNING

Do not smoke when checking the fuel system.
Fuel can ignite or explode, causing severe inju-

ry or property damage. Make sure there are no
open flames or sparks in the area, including pi-
lot lights from water heaters or furnaces.
