Hi Mike,
Sorry, just was having a 'duh' moment. I couldn't tell from the pictures if you were comparing old and new, or requesting parts, or what. I get it now. I'm doing the same thing as you, and I have no experience at all with motorized bikes. With common tools too. No lathe, or ways to fabricate parts to join old and new. A definite challenge. What makes my build worse, is I'm combining old parts and a new era motor. Everything has to be adapted, very little is an easy swap. Flex pipe in a WC1 exhaust manifold? Nope, you have to make a piece to make it fit securely. The thing is, I'd like to document all of the things that I needed to alter to make each step in the installation work, but it would take up lots of posts and I'm not even sure that there's anyone that is all that interested, since nobody but me is foolish enough to put a modern motor, outfitted with early parts, in an early bike. Maybe together we can add our experiences with certain parts of the installation as it progresses, to answer the most common questions about any given task.
