which could lead to an accident.

NOTICE
Never turn an adjusting mechanism be-
yond the minimum and maximum settings.
TIP
 When turning a damping force adjuster in
direction (a), the 0 click position and the 1
click position may be the same.
 Although a damping force adjuster may
turn or click beyond the stated minimum
settings, such adjustments are ineffective
and may damage the suspension.
Spring preload
1. Elevate the vehicle and place a suitable
stand under the frame.
2. Loosen the locknut.
3. 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.
