Adjusting the shock absorber
assembly
This shock absorber assembly is
equipped with a spring preload adjust-
ing ring.
It is recommended to have a Yamaha
dealer adjust the spring preload. How-
ever, if you choose to make this adjust-
ment yourself, obtain a special wrench
at a Yamaha dealer.
NOTICE
ECA10101
To avoid damaging the mechanism,
do not attempt to turn beyond the
maximum or minimum settings.
1. Loosen the locknut.
2. To increase the spring preload and
thereby harden the suspension,
turn the adjusting ring in direction
(a). To decrease the spring pre-
load and thereby soften the sus-
pension, turn the adjusting ring in
direction (b).
The spring preload setting is deter-
mined by measuring distance A,
shown in the illustration. The short-
er the distance A is, the higher the
spring preload; the longer distance
A is, the lower the spring preload.
3. Tighten the locknut to the specified
torque.
NOTICE:
Always tighten
the locknut against the adjust-
ing ring, and then tighten the
locknut to the specified
torque.
