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 1.0 mm
(0.04 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.
