Fork felt great first two weeks. Super sensitive beginning of the stroke felt very plush, very active. Beginning last week the fork has stiffened up considerably as if someone turned in the compression and gate knobs all the way. The fork feels locked out almost, the knobs are completely unscrewed counter-clockwise though. It's as if there's some type of restriction (massive amounts of dirt in the fork or something ridiculous), the controls are busted and ARE somehow turned in without physically being turned clockwise, or like the pressure has been pumped up to a million. Any ideas anyone? Very very strange...I'm lost.

maybe it's the self-pressurisation phenomena that some cartridge based Marzocchis experience?
anyways you wont know until you crack it open

Actually easier than pulling the crowns off is to just undo the pinchbolts on one side first (say undo the damper side crown pinchbolts first), then bounce on the fork whilst on the bike and see how it feels, then do those ones back up and try it with the other side.keen said:
Ok...I try to explaine but my English not so good!
Firts of all, lower the presure to the half of what was the right amount for before the problem appears.
When the fork feels much better now, loose the bolt on the bottom of the left outer leg. Now oil will come out with much more presure the normal! If this all happens, your fork (SoloAir unit) leaks air! This air causes some kind of second airspring between the inner and the outer tube in the left leg.
You have to disasamble the outer tubes an fix the lower sealing of the SoloAirunit. Don´t forget to unpresure the SoloAir before disasambly!!!

Pull out the cartridge, and take a look at the o-rings, spray with alchy hall, and make sure to only but 5cc of oil in the positive chamber, just enough to make it moist. I've accidentally put too much fluid in the + chamber and it makes it feel as you describe...

sehr interesting, so basically you encountered bleeding from the negative chamber in the bottom of the stanchion, to the space between the lowers and the stanchion.
thinking of it its clear that the result would be additional air preload that wont be compensated for by the solo air automatic-positive-to-negative-bleed system.
these forks require regular maintenance. once a month if you ride a lot.
It's a bad seal in the bottom of the fork that is creating the problem. Call Sram, they'll fix it for you.
