Keeping with the ignition, here is a better photo of the internals. Everything is MUCH nicer and newer than any AV7 I have worked on. Big Ole condensor that is bolted down upside down with a special tract that the wire follows to avoid being chewed up.
Onto the cylinder. It's a standard motobecane stud pattern, and the cylinder has somem very nice porting, if a little conservative on the exhuast side of things. The biggest thing is look at these massive case transfers!
I don't really know what they were thinking with these. They are absolutely massive. The outstripe the transfers in my Vespa Sacre cases by 25%.
In comparison, I've outlined the case transfers onto the already very large cylinder transfers.
At this point, I am not sure what my plan is for re-assembly of the top end. That bottleneck is a SEVERE interruption in the flow of the transfers, but I don't think that I want to try and match the cylinder to the cases. Mostly because their is no material backing the portion above the stock ports, so my work would have to be very shallow to avoid blowing through. I may go this route, or look into a bigger displacement cylinder.
