I went round and round with the same issues, my stock shock was harsh at the standard setting and with all the bad reports I've read about the stock shock I thought I'd just rebuild , respring and revalve to get a better ride and then just for the Hell of it I thought I'd knock the preload down to the soft position. With Ricor's in the forks and the reset rear shock I went out and pounded the hardest terrain I could find and the bike just floated over everything, no harsh jolts no bottoming out in the rear the bike was 100% better. I ride this bike hard off road and it sees very little pavement. Maybe my shock is an odd ball but I won't even think about touching it now until it needs a rebuild. I'm just saying that it might be worth your while to mess with the preload first and maybe save yourself $600.00.
