NOTE:
If the drive chain is difficult to re-
move, remove the wheel axle first,
and then lift the wheel upward
enough to remove the drive chain
from the rear sprocket.
The drive chain cannot be disas-
sembled.
7. While supporting the brake
caliper bracket, pull the wheel
axle out, and then remove the
wheel.
ECA11070CAUTION:
Do not apply the brake after the
wheel has been removed together

Make sure that there is enough
space between the brake pads
before installing the wheel.

er the rear wheel so that it is on
the ground.
4. Adjust the drive chain slack. (See
page 6-23.)
5. Tighten the axle nut to the speci-
fied torque.
Tightening torque:
Axle nut:
150 Nm (15.0 m·kgf, 108 ft·lbf)

Troubleshooting
Although Yamaha motorcycles receive
a thorough inspection before shipment
from the factory, trouble may occur
during 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.
