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 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).
3. Tighten the locknut to the specified
torque. NOTICE: Always tighten the
locknut against the adjusting nut, and
then tighten it to the specified torque.
