Before & After Competition Maintenance
• 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.
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.
When adjusting the left fork air pressures to the
recommended air pressures adjust the rebound and
compression damping adjuster to the standard
settings.
Do not adjust the left fork air pressure to less than
the minimum calculated value or more than the
maximum calculated value.
