14. Check that the O-ring (12) on the fork
damper assembly (4) is in good condition.
Apply the recommended fork oil to the O-
ring.
15. Pull up the fork assembly (1) slowly and
install the fork damper assembly into the
outer tube.

16. Insert both fork legs into the fork clamps.
Tighten the fork bridge lower pinch bolts (13)
to the specified torque:
15 Ibf·ft (20 N·m, 2.0 kgf·m)

17. Tighten the fork damper (14) to the specified
torque using a lock nut wrench (15).
Actual:
25 Ibf·ft (34 N·m, 3.5 kgf·m)
Torque wrench scale reading:
23 Ibf·ft (31 N·m, 3.2 kgf·m), using a 20 in
(50 cm) long torque wrench.
When using a lock nut wrench, use a 20 in (50
cm) long deflecting beam type torque 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.

18. For ease of releasing air pressure after the
forks are installed, loosen the fork bridge
lower pinch bolts and position the outer tubes
so that the fork air pressure release screws
(16) are in front of the compression damping
adjusters (17).
Align (18) the top of the outer tube (19) with
the top surface of the fork top bridge (20).

20. Tighten the fork bridge upper pinch bolts (21)
to the specified torque:
16 Ibf·ft (22 N·m, 2.2 kgf·m)
NOTICE
Over-tightening the pinch bolts can deform
the outer tubes. Deformed outer tubes must be
replaced.
