Yo, so I jacked the Van back up to 130mm and decided to change the oil.

I made sure to cycle the damper several times to get the old oil completely out. The fork was PUSH'd last year. I referred to the Fox manual for oil levels:

155cc R. leg
30cc L. leg

When I got it all back together, I only had 4" of travel. I drained 10cc out of the damper side and the travel increased a little. I drained another 10cc out and I was back to full 130mm

I guess after a PUSH, you need to use 135cc in the right leg.
