Just rebuilt my Revelation U-Turn, orings looked fine, so I didn't replace any. Put it back together, and when pumped to spec with pos and neg air chambers the same (150psi for 185lbs), the fork is sitting around 135mm with U-Turn fully extended. Dropping the neg pressure to around 110psi gets the fork back to 150mm. Can't say for sure whether or not it acted like this before I pulled it apart. Whats going on?
