I also just got my ULT and I can't get it to work. I have tried 2, 3, and 4 shims (.005) and can't seem to get it right. I have 3 in right now and the bolt sticks. 2 or 4 shims is even worse. I have oiled up the ULT and the value and still nothing.

If I put my basic on/off back in my RT fires fine. I'm not sure what the problem is. Plz help!

I have a RT Pro x-value and ULT.
