Using the alignment marks on each
side of the swingarm, make sure that
both chain pullers are in the same po-
sition for proper wheel alignment.
3. Tighten the axle nut, then the lock-
nuts to their specified torques.
Tightening torques:
Axle nut:
105 Nm (10.5 m·kgf, 75 ft·lbf)
Locknut:

To adjust the drive chain slack
1. Loosen the axle nut and the lock-
nut on each side of the swingarm.
2. To tighten the drive chain, turn the
drive chain slack adjusting bolt on
each side of the swingarm in di-
rection (a). To loosen the drive
chain, turn the adjusting bolt on
each side of the swingarm in di-
rection (b), and then push the rear
wheel forward. NOTICE: Improp-
er drive chain slack will over-
load the engine as well as other
vital parts of the motorcycle
and can lead to chain slippage
or breakage. To prevent this
from occurring, keep the drive
chain slack within the specified
limits.

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.
EWA15141
WARNING0
When checking the fuel system, do
not smoke, and make sure there
are no open flames or sparks in the
area, including pilot lights from wa-
ter heaters or furnaces. Gasoline or
gasoline vapors can ignite or ex-
plode, causing severe injury or
property damage.
