Front Suspension Adjustments
25. Tighten the fork damper lock nut (1) fully and
measure the thread length (A) as shown.
Standard: 0.7 – 0.8 in (19 – 20 mm)
26. Apply fork oil to the O-ring (11) and install it
to the fork cap (12). Install the fork cap to the
fork damper rod (10). Tighten the fork cap
fully by hand.
27. Measure the length of the fork damper lock nut
(1) and fork cap (12) clearance.
Standard: 0.04 – 0.08 in (1.0 – 2.0 mm)
If the clearance is out of specification, check the
fork damper lock nut and fork cap installation.
28. Tighten the fork damper lock nut (1) to the fork
cap (12) closely by hand. Tighten the fork
damper lock nut to the specified torque:
21 lbf·ft (29 N·m, 3.0 kgf·m)
29. Insert both fork legs into the fork clamps.
Tighten the fork bridge lower pinch bolts (13)
to the specified torque:
15 lbf·ft (20 N·m, 2.0 kgf·m)
30. Tighten the fork cap (12) to the specified
torque using the open end wrench (14):
Actual:
33 lbf·ft (45N·m, 4.6 kgf·m)
Torque wrench scale reading:
31 lbf·ft (42 N·m, 4.3 kgf·m)
The shape of the fork cap increases the torque
wrench’s leverage, so the torque wrench reading
will be less than the torque actually applied to the
fork cap.
31. Adjust the air pressure to specification.
Specified air pressure:
35 psi (240 kPa, 2.4 kgf/cm
