hey corbit. I posted on this thread a while ago saying that I had a strange vibration as well. Mine turned out to be a broken motor mount.

 

well, since this thread keeps popping up, here I am.

I never did figure out exactly what the problem was. I think it was a combination of a bunch of little things. Seemed like every tims i fixed something it got a bit less until it was just gone. Another thing is that it may have been the bearings breaking in in the engine...i had a machine shop press them in and wasnt entirely pleased with the job they did. So, I would say that may have been part of the cause and then fixed itself after a thousand or so miles.

sorry i cant give you guys a easy fix, although i doubt your problems are the same as mine. You might want to read thru the first part of the thread and try all the **** that didnt work for me.
