3.
Tighten the locknut to the specified
torque.
NOTICE:
Always tighten the
locknut against the adjusting nut, and
then tighten the locknut to the speci-
fied torque.

Adjusting the spring preload of the
center shock absorber and the rear
torsion springs
The spring preload can be adjusted by turn-
ing the adjusting nut on the center shock ab-
sorber and the adjusters on the rear torsion
springs. Adjust the spring preload as follows.
Center shock absorber
1.
Loosen the locknut.
2.
To increase the spring preload and
thereby harden the suspension, turn the
adjusting nut in direction (a). To decrease
the spring preload and thereby soften
the suspension, turn the adjusting nut in
direction (b).
TIP
The spring preload setting is determined by
measuring distance A, shown in the illustra-
tion. The longer distance A is, the higher the
spring preload; the shorter distance A is, the
lower the spring preload.
3.
Tighten the locknut to the specified
torque.
NOTICE:
Always tighten the
locknut against the adjusting nut, and
then tighten the locknut to the speci-
fied torque.
