• Suspend the front wheel above the ground and
adjust the left fork air pressures.
For details on left fork air pressures
adjustment, refer to page 136.
Left fork:
(1) (2) (3)
(1) inner chamber air valve
(2) outer chamber air valve
(3) balance chamber air valve
When adjusting the left fork air pressure, adjust the
inner chamber air pressure first, then outer
chamber air pressure, and finally balance chamber
air pressure.
When releasing the balance chamber air pressure,
a small amount of fork oil spraying from the
balance chamber air valve is normal. This will not
affect the fork performance.
