NOTICE
ECB01091
Never turn the adjusting mechanism beyond
the minimum and maximum settings.
Adjust the spring preload as follows.
1. Elevate the vehicle and place a suitable stand
under the frame.
2. Loosen the locknut.
3. Turn the spring preload adjusting nut in direc-
tion (a) to increase the spring preload and
thereby harden the suspension, and in direc-
tion (b) to decrease the spring preload and
thereby soften the suspension.
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 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).
