Adjusting the rear shock absorber as-
sembly (YFM70RSBG)
The spring preload can be adjusted to suit the rid-
er’s weight and the riding conditions.
NOTICE
ECB01091
Never turn the adjusting mechanism beyond
the minimum and maximum settings.
Adjust the spring preload as follows.
1. Loosen the locknut.
2. 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).
