the entire range of fork travel.
Air is an unstable gas; it increases in pressure as it is
worked (such as in a fork), so the fork action on this
motorcycle will get stiffer as the race progresses.
Release built-up air pressure from the fork legs after
practice and between motos.
Be sure the fork is fully extended with the front tire off
the ground.
