Well, after a bit of digging, I can conclusively say that this frame is utter junk. it got hit in the rear and is tweaked both to the left and the upper portion is shunted so hard that the fuel tank won't mate up to the rear mount.

I'm not giving up on the idea of having a bike, and parts from this one factor in to what I'd like to build... But it's gonna call for buying a whole other non-turbo XJ650... So that's gonna be a long-term thing. Just gonna tear it down for now and sell anything that might be good other than the 4-1 turbo manifold and the fairings. those are staying mine.
