Troubleshooting

Although Yamaha machines receive a rigid in-
spection before shipment from the factory,
trouble may occur during operation. Any prob-
lem in the fuel, compression, or ignition sys-
tems 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 dealer-
ship have the tools, experience, and know-
how to properly service your machine. Use
only genuine Yamaha parts on your machine.
Imitation parts may look like Yamaha parts,
but they are often inferior. Consequently, they
have a shorter service life and can lead to ex-
pensive repair bills.

WARNING

POTENTIAL HAZARD
Checking the fuel system while smok-
ing or near an open flame.

WHAT CAN HAPPEN
Fuel can ignite or explode, causing se-
vere injury or property damage.

HOW TO AVOID THE HAZARD
Do not smoke when checking the fuel
system. Make sure there are no open
flames or sparks in the area, including
pilot lights from water heaters or furnac-
es.
