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 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.

Rebound damping force
Turn the rebound damping force adjusting
screw in direction (a) to increase the rebound
damping force and thereby harden the damp-
ing, and in direction (b) to decrease the re-
bound damping force and thereby soften the
damping.Compression damping force
Fast compression damping force
To increase the fast compression damping
force and thereby harden the compression
damping, turn the fast compression damping
force adjusting bolt in direction (a). To de-
crease the fast compression damping force
and thereby soften the compression damp-
ing, turn the adjusting bolt in direction (b).
