you may say that i am creating a path of least resistance for the oil by creating a freelift at the rebound stack. By doing so, with small, high speed hits(stutter bumps) small quantities of oil can flow freely so creating no resistance, rebound is returning quickly to full length. If speed increases with bigger hits, oil forces are equally high, bending the shimstack, so damping increases likewise.
I strongly have the feeling that rebound is the culprit with small highspeed impacts, creating packing.
But perhaps i will create a pogo effect, i just have to see, i guess.
Terry, by the way, thnks simplifying things a bit! thnks for joining.
