 A special wrench can be ob-
tained at a Yamaha dealer to
make this adjustment.
 The spring preload setting is
determined by measuring
distance A, shown in the illus-
tration. The longer distance A
is, the lower the spring pre-
load; the shorter distance A
is, the higher the spring pre-
load. With each complete
turn of the adjusting nut, dis-
tance A is changed by 1.5
mm (0.06 in).
