I just got my penske 8981 installed and took the bike for a quick test ride around the block. I hope I put this thing in properly, I can't really see any way to do it incorrectly and it all still bolt up. The tires were cold, and it's a little cool outside (60), but when I made a couple of easy right turns going around the block the back tire was stepping out on me, and it just didn't feel right, almost like I had a flat tire or the wheel was loose. Is there that much feeling with this shock? Is it that much more sensitive than stock? Or is it so much stiffer that it's not giving as much and causing to rear to bounce over small bumps?
