NOTE:
8 A special wrench is needed to
make this adjustment and it can
be obtained at a Yamaha dealer.
8 The spring preload setting is
determined by measuring dis-
tance A, shown in the illustration.
The shorter the distance A is, the
higher the spring preload; the
longer distance A is, the lower
the spring preload.
Spring preload:
Minimum (soft):
Distance A = 236 mm (9.3 in)
Standard:
Distance A = 228 mm (9.0 in)
Maximum (hard):
Distance A = 224 mm (8.8 in)
3. Tighten the locknut to the speci-
fied torque.
