Always adjust the shock absorber as-
semblies on the left and right side to the
same setting. Uneven adjustment can
cause poor handling and loss of stability,
which could lead to an accident.
NOTICE
ECB00091
Never turn an adjusting mechanism be-
yond the minimum and maximum settings.
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.
TIP
A special wrench can be obtained at a
Yamaha dealer to make this adjustment.
The spring preload setting is determined by
measuring distance A, shown in the illustra-
tion. The shorter distance A is, the higher
the spring preload; the longer distance A is,
the lower the spring preload.
