Penske Racing Shocks 8900 Series - Manual (Page 11)

Basic Start-Up Procedure
The following setup procedures are basic recommendations for reaching an
initial starting point using double adjustable Penske Racing Shocks. This
procedure is ideal for use on an open test schedule. A race weekend may not
allow enough time. Start by making the compression adjustments as described
below, until it feels right, then move to the rebound adjustments.
COMPRESSION
The idea is to set the compression damping forces to suit the bumps in critical
areas, such as corners, corner exits and braking zones.
Step 1 -Set the rebound adjuster at mid-range.
Step 2 -Starting with the compression setting at mid-range, ride a lap then
return. If the bike feels harsh, decrease the settings one click at a time until the
harshness goes away. If the bike feels plush, increase the setting on click at a
time until the bike becomes harsh, loses tire compliance and traction. At this
point you know that you have gone too far on the compression settings; back off
one click.
COMPRESSION
The idea is to tighten up the bike, stabilize the platform and eliminate the
floating "Cadillac feeling". This will also reduce the rate of weight transfer.
Step 1 -With the rebound setting at mid-range, add 4 or clicks of rebound
adjustment at a time, then return to continue the process until the bike becomes
"skittish" or the rear wheel hops under braking. At this point you know you have
gone too far on the rebound settings, back off one click at a time for final
balance.
Once again, this is a basic procedure for finding your initial setup for a given
track. If you find that you are at the end of your adjustment range and feel that
the bike is feeling better, you will need to revalve the shocks to allow for further
adjustment in the given direction.
