Have you torn the carbs apart and cleaned them? how about the water trap? Needle and seat alright or worn?
Also, check the Jet needle and the Needle Jet. The jet needle, is on the end of the throttle and the Jet Needle is IN the carb, in the venturi opening.
question, what size are YOUR carbs for the 600? are they VM30SS or VM34SS?
also, check your pilot jet and main jet.
