TUN
Setting of spring after replacement
After replacement, be sure to adjust the spring
to the set length [sunken length 75 ~ 85 mm
(3.0 ~ 3.3 in)] and set it.
1. Use of soft spring
Set the soft spring for less rebound damp-
ing to compensate for its less spring load.
Run with the rebound damping adjuster
one or two clicks on the softer side and
readjust it to suit your preference.
2. Use of stiff spring
Set the soft spring for more rebound damp-
ing to compensate for its greater spring
load. Run with the rebound damping
adjuster one or two clicks on the stiffer side
and readjust it to suit your preference.
*Adjusting the rebound damping will be fol-
lowed more or less by a change in the com-
pression damping. For correction, turn the
compression damping adjuster on the
softer side.
CAUTION:
When using a rear shock absorber other
than currently installed, use the one whose
overall length a does not exceed the stan-
dard as it may result in faulty performance.
Never use one whose overall length is
greater than standard.
