Adjusting the shock absorber
assembly
This shock absorber assembly is
equipped with a spring preload adjust-
ing ring.
TIP
A special wrench is required to make
this adjustment. See you Yamaha deal-
er.
NOTICE
ECA10102
To avoid damaging the mechanism,
do not attempt to turn beyond the
maximum or minimum settings.
1. Loosen the locknut.
2. Turn the adjusting ring in direction
(a) to increase the spring preload.
Turn the adjusting ring in direction
(b) to decrease the spring preload.
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.
