Adjusting The Front Fork - Yamaha FJ-09 2014 Owner's Manual

Adjusting the front fork

WARNING
Always adjust the spring preload on
both fork legs equally, otherwise
poor handling and loss of stability
may result.
Each front fork leg is equipped with a
spring preload adjusting bolt. The right
front fork leg is equipped with a re-
bound damping force adjusting screw.
NOTICE
To avoid damaging the mechanism,
do not attempt to turn beyond the
maximum or minimum settings.
Spring preload
To increase the spring preload and
thereby harden the suspension, turn
the adjusting bolt on each fork leg in di-
rection (a). To decrease the spring pre-
load and thereby
suspension, turn the adjusting bolt on
each fork leg in direction (b).

The spring preload setting is deter-
mined by measuring distance A,

shown in the illustration. The shorter
distance A is, the higher the spring pre-
load; the longer distance A is, the lower
the spring preload.

Minimum (soft):
Distance A = 19.0 mm (0.75 in)
Standard:
Distance A = 16.0 mm (0.63 in)
Maximum (hard):
Distance A = 4.0 mm (0.16 in)
Rebound damping force
The rebound damping force is adjust-
ed on the right front fork leg only.
To increase the rebound damping
force and thereby harden the rebound
damping, turn the adjusting screw in
direction (a). To decrease the rebound
damping force and thereby soften the
rebound damping, turn the adjusting
screw in direction (b).
