Fork Oil Amount Adjustment
The fork oil amount affects only the final 100 mm
(4 in.) of fork travel. A higher oil amount will make
the fork rebound more quickly. A lower oil amount
will make the fork rebound more slowly.
•
Fork Springs
Optional springs, softer and stiffer than standard,
are available.
•
Fork Height
Steering is greatly affected by the fork height (how
much the outer fork tubes protrude above the steer-
ing stem head). The less the fork tube protrudes,
the lighter the front end becomes and the greater
the tendency for understeering and washout due to
weight biasing. Increasing the amount of fork tube
protrusion has opposite effects. Be sure that the
front tire does not touch the fender when the fork
is fully compressed. Make this adjustment in 10 mm
(0.39 in.) steps.
NOTICE
The right and left fork tubes must be adjusted
evenly.
Air Pressure Adjustment
The standard air pressure in the front fork legs is
atmospheric (0 kPa, 0 kgf/cm², 0 psi). Air pressure
in the fork legs increase with normal use, so the fork
action stiffens during operation. Release air pres-
sure from the fork legs prior to each race through the
air pressure relief screw located in left front fork base
valve assembly and right front fork top plug. Make
sure the front forks are fully extended with the front
wheel off the ground when releasing the pressure.
•
Raise the front wheel off the ground using a jack
(special tool: 57001-1238) and attachment (spe-
cial tool: 57001-1608).
•
Remove the screw on each front fork top plug to
let the air pressure equalize. Then, tighten the
screws.
