2. Turn the spring preload adjusting nut in direc-
tion (a) to increase the spring preload and
thereby harden the suspension. Turn in direc-
tion (b) to decrease the spring preload and
thereby soften the suspension.
TIP
The spring preload setting is determined by
measuring distance A, shown in the illustration.
The shorter distance A is, the greater the spring
preload. The longer distance A is, the lesser the
spring preload.
Each complete turn of the adjusting nut chang-
es distance A by 1.5 mm (0.06 in).
