TIP
•
Be sure to remove all dirt and mud from around
the locknut and adjusting ring before adjust-
ment.
• The length of the spring (installed) changes 1.5
mm (0.06 in) per turn of the adjusting ring.
e. Tighten the locknut.
Rebound damping
NOTICE
ECA24370
Do not turn the adjuster forcibly beyond its
adjusting range.
1. Adjust:
• Rebound damping
a. Turn the adjuster “1” in the direction of “a”
or “b” to make an adjustment.
TIP
Although the total number of clicks of a damping
force adjusting mechanism may not exactly
match the above specifications due to small dif-
ferences in production, the actual number of
clicks always represents the entire adjusting
range. To obtain a precise adjustment, it would
be advisable to check the number of clicks of
each damping force adjusting mechanism and
to modify the specifications as necessary.

sion damping)

Do not turn the adjuster forcibly beyond its
adjusting range.
