This is a n.o.s. (new old shit) front knucklehead. When hd machined the casting, the sunk the cutter into the head a little to deep, and cut into the combustion chamber. There is no way this bike would idle correctly with a gaping hole in the intake port. I welded it up and fixed the head into a useable piece. Any day that you learn something, or see something new is a good day.
