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

17.Tighten the fork damper (14) to the specified
torque using a lock nut wrench (15).
Actual:
34 N·m (3.5 kgf·m, 25 lbf·ft)
Torque wrench scale reading:
31 N·m (3.2 kgf·m, 23 lbf·ft), using a 50 cm
(20 in) long torque wrench.
When using a lock nut wrench, use a 50 cm (20
in) 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 the outer tube (19) with the
top surface of the fork top bridge (20).

to the specified torque:
22 N·m (2.2 kgf·m, 16 lbf·ft)
NOTICE
Over-tightening the pinch bolts can deform the
outer tubes. Deformed outer tubes must be
replaced.
