Just taken all the downdraught carb nonsense off a 650 V Star and put an inch and a quarter S.U. on it. Made the manifold out of 2 Evo manifolds, cut and shut, insides welded and sanded back. Fired up straight away, idles beautifully. Just need to sort the throttle position sensor and she'll be sorted. Runs ok and rides well enough, just a bit of a flat spot to iron out, sounds great with the fishtails on.
