Important preliminary
information:
-
Link lengths and mounting
angles.
-
Shock compressed and
extended lengths.
-
Shock and mounting
angles.
-
Link and shock mounting
positions on the birdcage.
Set up the KB Rear
Suspension Simulator:
1) With the locking pin
installed, set the static height to zero and tighten the suspension
travel stop knob.
2) Set the link pivot points
and the lower shock mounting points to the desired position on the
birdcage.
3) Set the longest link to
length and attach it's chassis end to the stationary frame vertical. 4)
Set the shorter link to length and attach it's chassis end to the
movable frame vertical. 5)
Set the link angles. 6)
Set the shock travel stops to the appropriate extended and
compressed lengths for the shocks you will be using. 7)
Set the upper shock mounting points and shock angle on the
stationary frame. 8)
Zero the shock travel telltales (o-rings) and set the rear steer
pointer to zero.
Measure with the KB
Rear Suspension Simulator:
9) While holding the
birdcage center knob, remove the lock pin. 10)
Loosen the suspension travel stop knob and move the birdcage
assembly through the desired amount of bump and rebound travel. 11)
Observe the amount of rear steer, birdcage index, shock travel,
shock angle change, and link thrust angle change. For best
measurement accuracy, tighten the suspension travel stop knob before
taking a measurement. Record measurements as desired. 12)
Change desired link lengths, link angles, shock placement or
attachment points on the existing layout or repeat steps 1) through
8) for a different layout. Then repeat steps 9) through 11) to
observe the difference in rear steer, birdcage index, shock travel,
shock angle change, and link thrust angle change. For best
measurement accuracy, tighten the suspension travel stop knob before
taking a measurement. Record measurements as desired.
