●
A special wrench can be ob-
tained at a Yamaha dealer to
make this adjustment.
●
The spring preload setting is
determined by measuring dis-
tance A, shown in the illustra-
tion. The longer distance A is,
the lower the spring preload;
the shorter distance A is, the
higher the spring preload.
With each complete turn of
the adjusting nut, distance A
is changed by 1.5 mm (0.06
in).
3. Tighten the locknut to the specified
torque.
NOTICE:
Always tighten
the locknut against the adjust-
ing nut, and then tighten the
locknut to the specified torque.

Rebound damping force
To increase the rebound damping force
and thereby harden the rebound damp-
ing, turn the adjusting screw in direction
(a). To decrease the rebound damping
force and thereby soften the rebound
damping, turn the adjusting screw in di-
rection (b).
