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.
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 illustra-
tion. The shorter distance A is, the lower the
spring preload; the longer distance A is, the
higher the spring preload. With each com-
plete turn of the adjusting nut, distance A is
changed by 1.5 mm (0.06 in).
