would be advisable to check the number of clicks
or turns of each damping force adjusting mecha-

Spring preload
1. Loosen the locknut.
2. Turn the spring preload adjusting nut in direc-
tion (a) to increase the spring preload and
thereby harden the suspension, and in direc-
tion (b) to decrease the spring preload and
thereby soften the suspension.

(b)
1. Spring preload adjusting nut
2. Locknut
3. Special wrench
TIP
A special wrench can be obtained at a Yamaha
dealer to make this adjustment.
The spring preload setting is determined by
measuring distance A, shown in the illustration.
The shorter distance A is, the higher the spring
preload; the longer distance A is, the lower the
spring preload. With each complete turn of the
adjusting nut, distance A is changed by 1.5 mm
(0.06 in).

Distance A = 268.0 mm (10.55 in)
Distance A = 262.0 mm (10.31 in)
Distance A = 253.0 mm (9.96 in)
