    What psi for a 04 Ultra Fatty DL Headshok?

    I've been searching around and can't find an actual amount. C'dales website says that I should be running 85 psi, but this must be on newer models. I've never actually done anything to the shock until last week . I decided my shok was running way too soft and when I went to air it up it was around 100 psi. I read somewhere that psi = to body weight was about right. Is this true? I put it up to 170 and it seems pretty stiff (too stiff?). Anybody have the instructions from a 2004 Headshok? I ride super rooty and rocky trails. Should I ere on the stiff or soft end of the range for my weight.

    BTW after lurking around for a couple years I finaly made a post!

    I match psi to how much I weight in pounds, maybe about 10% less air in the headshok. I have an older headshok 02'.

    Thank you, don't know how I missed that. Looks like I'm slightly over, should be closer to 130-140 psi instead of 170ish. Its been riding pretty good like that though!
