SETTING OF SPRING AFTER
REPLACEMENT
After replacement, be sure to adjust the spring to
the set length [sunken length 90–100 mm (3.5–
3.9 in)] and set it.
1. Use of soft spring
•
Adjust to decrease rebound damping force to
compensate for less spring load. Run with the
rebound damping force adjuster one or two
clicks turned out, and readjust it to suit your
preference.
2. Use of stiff spring
•
Adjust to increase rebound damping force to
compensate for greater spring load. Run with
the rebound damping force adjuster one or
two clicks turned in, and readjust it to suit your
preference.
TIP
Adjusting the rebound damping force will be fol-
lowed more or less by a change in the compres-
sion damping force. For correction, adjust to
decrease compression damping force.
WARNING

When using a rear shock absorber other
than currently installed, use the one whose
