Here it is in the current state.  I was messing around with it with my buddy the other day.  Gotta replace the clutch plates, shorten all the cables and sadly going to wind up pulling the motor again.

When I bought it, the front left cylinder was the one that was seized up.  We found some new marks on that cylinder bore and also, that side gets super hot super fast while the right side of the motor stays nice and cool.  When I got it, I didn't open up the bottom end but at this point if the motor is going to be out again to see what's going on, might as well open the bottom to see what's happening and replace the crank and rod bearings.  Sad day but I want to be able to ride this bastard.

IT RUNS!!

Got to ride it for the first time this past Sunday.   Having a problem with the fuel flow though.  It seems like it creates a vacuum somewhere as i cannot get the fuel to flow through the filter down into the carburetors properly.
