I don’t know, I want to go faster, i have a stock 650 and thinking to put a bigger carburetor, a Solex pbic 34 might be the one since it can be found quiet cheap and I don’t want to spend a small fortune on a carb. A faster cam, suitable for daily running so not the wilder one and maybe bigger valves, combined with my 500 lighter flywheel and sport exhaust I think little car is going to kick a little and maybe reach 30hp. May I hear you opinion on valve sizes again for daily use, which camshaft to choose and what about this solex pbic 34 carb?
