Spring preload
1. Loosen the locknut.
2. Turn the spring preload adjusting nut in
direction (a) to increase the spring pre-
load and thereby harden the suspension,
and in direction (b) to decrease the spring
preload and thereby soften the suspen-
sion.
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.
