The more I tear into it, the more I wonder. Now I found the tabbed camshaft thrust washer behind the cam sprocket, and the tab was bent and twisted. I am ready to split the cases, so we'll see what I find in there, so far I can see a roller bearing on the timing side. I am starting to realize not all supposed "experts" are. I have found too many bodges and butchery on this bike. All from a well know and still in business shop. Some of the frame stuff might have been the PO, But I know the shop did the superblend bulletin.
