Minimum oil 10.1 US oz Slightly softer as
capacity (300 cm 3 ) it nears full

Be sure the oil capacity is the same in both fork
legs.
6. Check that the O-ring (8) on the fork damper
(2) is in good condition. Apply the
recommended fork oil to the O-ring.
Temporarily install the fork damper to the
outer tube (1).
After installing the fork leg (page 110),
tighten the fork damper to the specified torque
using the lock nut wrench:
Actual:
22 lbf·ft (30 N·m, 3.1 kgf·m)
Torque wrench scale reading:
20 lbf·ft (27 N·m, 2.8 kgf·m), using a 20 in
(50 cm) long deflecting beam type torque
wrench.
When using the lock nut wrench, use a 20 in (50
cm) long deflecting beam type torque wrench
with a lock nut wrench. The lock nut wrench
increases the torque wrench's leverage, so the
torque wrench reading will be less than the
torque actually applied to the fork damper.
