Need advice: 2009 Revelation Dual Air oil volumes for full travel
 

Hi - I just got a 2009 Revelation Dual Air, but cannot get the last inch of travel out of it, even with extremely low air pressures. I've been told that it's a relatively common problem from having too much oil installed by the factory. I have the tech manuals from the Rockshox website, but I'm wondering if any of you have experience with this and can tell me which portion of the fork I need to drain oil from.

Each leg has a top and bottom oil volume specified, so four quantities can be changed. Any ideas on which one it should be? Or two perhaps? Or do I simply have to drain it all and start from scratch?

Many thanks in advance...
