TIP
G A special wrench can be obtained at a Yamaha
dealer to make this adjustment.
G 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 1.5 mm
(0.06 in).
Spring preload setting:
Minimum (soft):
Distance A = 243.0 mm (9.57 in)
Standard:
Distance A = 233.0 mm (9.17 in)
Maximum (hard):
Distance A = 228.0 mm (8.98 in)
