The spring preload setting is deter-
mined by measuring distance A,
shown in the illustration. The shorter
distance A is, the higher the spring pre-
load; the longer distance A is, the lower
the spring preload. Re
boun d d ampin g force
To increase the rebound damping for-
ce and thereby harden the rebound
damping, turn the adjusting knob on
each fork leg in direction (a). To de-
crease the rebound damping force and
thereby soften the rebound damping,
turn the adjusting knob on each fork
leg in direction (b). Compression

To increase the compression damping
force and thereby harden the com-
pression damping, turn the adjusting
screw on each fork leg in direction (a).
To decrease the compression damp-
ing force and thereby soften the com-
pression damping, turn the adjusting
screw on each fork leg in direction (b).

Trou
bleshootin gAlthough 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.
WARNING
EWA15142
When checkin g the fuel system, d o
not smoke, an d make sure there are
no open flames or sparks in the ar-
ea, inclu din g pilot li ghts from water heaters or furnaces. Gasoline or
g
asoline vapors can i gnite or ex-
plo de, causin g severe injury or prop-
erty damag e.
