To increase the rebound damping
force and thereby harden the rebound
damping, turn the adjusting screw on
each fork leg in direction

Compression damping force

To increase the compression damping
force and thereby harden the compres-
sion damping, turn the adjusting screw

CAUTION:

_ 

Never attempt to turn an adjusting
mechanism beyond the maximum
or minimum settings.

NOTE:

_ 

Although the total number of clicks of a
damping force adjusting mechanism
may not exactly match the above spec-
ifications due to small differences 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 num-
ber of clicks of each damping force ad-
justing mechanism and to modify the
specifications as necessary.
