    I ran a set of 48mm novis on a twin piped XPL years ago. They were the F booster carbs though. They were reverse jetted with 160 lows and 140 highs. 160 is the biggest low speed you can get. It was a Big bore 951, and it liked a lot of fuel on the bottom. I don't know if that will work for you, but it might be a good starting point.
