Hi there Guy's, sorry don't wish to change this thread.......I'll probably start one on some racing bike theme........Yes I wanted to build a bike based on a true Vincent, and I do have the parts to do it. However, as I also have the bones of a new twin engine I wish to build that as a street bike........So that is why I bought a set of Comet cases and started to build a new engine to swap over for the 2 valve Jawa (ESO) engine that was in the racer I already had. I take a big interest in the all up weight of the machines as this gives a big advantage over heavy machines........This too was part of my reasoning for building a single racer rather than a twin, where the twin is much heavier and takes a lot more effort to stop. Before I stripped the bike it was 130 Kg's.......with the Vincent engine and many, many mods so far......minus the exhaust and the primary cover, it tips the scales at 120 Kg's at the moment. It all costs a damn fortune, and I think i'm completely nuts at times, but hey we all need our toys.......I always enjoy the challenge of it all.
