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 charts
represent quick and easy procedures
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
inferior, have a shorter service life and
can lead to expensive repair bills. Tightening torques:
Axle nut:
150 Nm (15.0 m·kgf)
Brake caliper bolt:
40 Nm (4.0 m·kgf)

CAUTION:Be sure to use motor oils that do not contain anti-friction mod-
ifiers. Passenger car motor oils (often labeled
“ENERGY CONSERVING II”) contain anti-friction additives
which will cause clutch and/or starter clutch slippage, result-
ing in reduced component life and poor engine performance.
