TIPAlthough 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.
EAU14794
Front fork bleeding
WARNING
EWA10201
Always bleed both fork legs, other-
wise poor handling and loss of sta-bility may result.
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 front fork as follows.
1. Lift the front wheel off the ground according to the procedure on
page 6-37.TIPWhen bleeding the front fork, there
should be no weight on the front end ofthe vehicle.
2. Remove the bleed screws and al- low all of the air to escape from
each fork leg.
1. Compression damping force adjusting screwCompression damping setting:Minimum (soft):
20 click(s) in direction (b)*
Standard: 14 click(s) in direction (b)*
Maximum (hard): 0 click(s) in direction (b)*
* With the adjusting screw fully turned
in direction (a)
