INSTRUMENT AND CONTROL FUNCTIONS
1. Locknut
4
2. Spring preload adjusting nut
 A special wrench can be ob-
tained at a Yamaha dealer to
make this adjustment.
 The spring preload setting is
determined
distance A, shown in the illus-
tration. The longer distance A
is, the lower the spring pre-
load; the shorter distance A
is, the higher the spring pre-
load. With each complete
turn of the adjusting nut, dis-
tance A is changed by 1.5
mm (0.06 in).
1. Distance A
Spring preload:
Minimum (soft):
Distance A = 218.5 mm (8.60 in)
Standard:YZ85(E)
Distance A = 215.0 mm (8.46 in)
Standard:YZ85LW(E)
by measuring
Distance A = 207.0 mm (8.15 in)
For Europe only: Distance A =
212.0 mm (8.35 in)
Maximum (hard):
Distance A = 202.5 mm (7.97 in)
3. Tighten the locknut to the speci-
fied torque. NOTICE: Always
tighten the locknut against the
adjusting nut, and then tighten
the locknut to the specified
torque.

Tightening torque:
Locknut:
35 Nm (3.5 m·kgf, 25 ft·lbf)
Rebound damping force
To increase the rebound damping
force and thereby harden the rebound
damping, turn the adjusting screw in
direction (a). To decrease the rebound
damping force and thereby soften the
rebound damping, turn the adjusting
screw in direction (b).
