Thanks for that PMK, it's quite interesting to see. Also it appears to have a two part alternator cover but unsure of what I can see, is that something the originals had?
Something else, I was watching an old scrapheap challenge that I put on for my son in which they had to lift things up with a crane to get points. One of them chained up an engine in a car and lifted!! out came a whole CB750 motor..............shame on them.
