Front fork blee din gWhen 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.

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 legs1. Remove the protector.
