Following the demise of a 650cc engine in a featherbed frame, we're rebuilding the bike with a 908cc engine from Norvil, more info on my blog link below http://nochangegiven.com/ncg/
The Norton's a runner, I've upped a short clip onto my site http://nochangegiven.com/ncg/
I've been thinking about that conversion myself. Nice looking and running in your video.
