Troubleshooting

Although Yamaha motorcycles
receive a rigid inspection before
shipment from the factory, trouble
may occur during operation.
Any problem in the fuel, compres-
sion, or ignition systems can cause
poor starting and loss of power.
The troubleshooting chart
describes a quick, easy procedure
for making checks.
If your motorcycle requires any
repair, bring it to a Yamaha dealer.
The skilled technicians at a
Yamaha dealership have the tools,
experience, and know-how to
properly service your motorcycle.
Use only genuine Yamaha parts on
your motorcycle. Imitation parts
may look like Yamaha parts, but
they are often inferior.
Consequently, they have a shorter
service life and can lead to expen-
sive repair bills.

3. Install the axle nut and let the

motorcycle down.
