CAUTION:
ECA10960
Be sure to install the rubber caps to
prevent dust, etc. from entering the
fork legs.
NOTE:
Although the total number of clicks of a
damping force adjusting mechanism
may not exactly match the above spec-
ifications due to small differences in
production, the actual number of clicks
always represents the entire adjusting
range. To obtain a precise adjustment,
it would be advisable to check the num-
ber of clicks of each damping force ad-
justing mechanism and to modify the
specifications as necessary.

Adjusting the shock absorber
assembly
This shock absorber assembly is
equipped with a spring preload adjust-
ing nut, a rebound damping force ad-
justing dial and a compression
damping force adjusting knob.
CAUTION:
ECA10100
Never attempt to turn an adjusting
mechanism beyond the maximum or
minimum settings.
Spring preload
1. Loosen the locknut.
2. To increase the spring preload and
thereby harden the suspension,
turn the adjusting nut in direction
(a). To decrease the spring pre-
load and thereby soften the sus-
pension, turn the adjusting nut in
direction (b).
NOTE:
●
A special wrench is needed to
make this adjustment and it can be
obtained at a Yamaha dealer.
●
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.
