WARNING
EWA10181
Always a djust both fork le gs equally,
otherwise poor han dlin g an d loss of
sta bility may result.
This front fork is equipped with re-
bound damping force adjusting screws
and compression damping force ad-
justing screws.
NOTICE
ECA10102
To avoi d d amag ing the mechanism,
d o not attempt to turn b eyond the
maximum or minimum settin gs.
Re boun d d ampin g force
1. Remove the protector.
2. Turn the adjusting screw in direc- tion (a) to increase the rebound
damping force. Turn the adjusting
screw in direction (b) to decrease
the rebound damping force. To
set the rebound damping force,
turn the adjuster in direction (a)
until it stops, and then count the
clicks in direction (b). 3. Install the protector.
TIP

Install the protector so that the
side with the notch is facing rear-
ward.
 When turning the damping force
adjuster in direction (a), the 0 click
position and the 1 click position
may be the same.
 When turning the damping force
adjuster in direction (b), it may
click beyond the stated specifica-
tions, however such adjustments
are ineffective and may damage
the suspension.

Front fork blee din g
When riding in extremely rough condi-
tions, the air temperature and pressure
in the front fork will rise. This will in-
crease the spring preload and harden
the front suspension. If this occurs,
bleed the air from each front fork leg.
WARNING
EWA10201
Always blee d b oth fork le gs, other-
wise poor han dlin g an d loss of sta-
b ility may result.
To bleed the front fork legs
1. Remove the protector.
2. Place the motorcycle on a suitable
stand. (See page 7-28.)
3. Make sure the front wheel is off the ground and the area near the
bleed screws is clean.
4. Remove the bleed screws. 5. Wait a few seconds, and then in-
stall the bleed screws.
6. Install the protector.
