Front fork bleedin g
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.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 7-28.TIPWhen bleeding the front fork, there
should be no weight on the front end of
the vehicle.2. Remove the bleed screws and al-low all of the air to escape from
each fork leg. 3. Install the bleed screws.
4. Lower the front wheel so that it is
on the ground, install the remov-
able sidestand, and then rest the
motorcycle on it.

Adjust the spring preload as follows. 1. Loosen the locknut.
2. To increase the spring preload and thereby harden the suspen-
sion, turn the adjusting nut in di-
rection (a). To decrease the spring
preload and thereby soften the
suspension, turn the adjusting nut
in direction (b).
