A special wrench can be ob-
tained at a Yamaha dealer to
make this adjustment.
The spring preload setting is
determined by measuring
distance A, shown in the illus-
tration. The longer distance A
is, the lower the spring pre-
load; the shorter distance A
is, the higher the spring pre-
load. With each complete
turn of the adjusting nut, dis-
tance A is changed by 1.5
mm (0.06 in).
3. Tighten the locknut to the speci-
fied torque.

To increase the rebound damping
force and thereby harden the rebound
damping, turn the adjusting screw in
direction (a). To decrease the rebound
damping force and thereby soften the
rebound damping, turn the adjusting
screw in direction (b).
