I wouldn't think that you would need to balance the carbs Dave, as they would beoth be working to the same cylinder.
I was thinking about a two carb manifold for the RB; a 24mm on each side of the engine. My reasoning was this. The manifold on the RB is partially obscured as it enters the reed cage. Why is 25% of the reed cage obscured? I haven't heard a decent explanation. However, if you cut out the ali in the manifold, as some tuners do already, and fitted two 24mm carbs, you would have the advantages of small carbs at low revs, and the same cross-sectional area as a 34mm carb at wide open throttle.
I suggested this to John Balcomb last week and he said that he'd try it if I built a manifold. I think that was his way of saying "go away and stop talking to me"
