Front fork bleeding

WARNING
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 7-35.
TIP
When 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.
