It's the way they are swirled and blended in the throat of the carb, from what he tells me, just like the swirl finish inside a worked head will improve the atomization. Fred has dyno'd the carbs on bone stock bikes and gotten 5-6 rwhp on the dyno. I am going to dyno mine as well and post numbers as soon as I can. He also told me that I will be using a smaller main jet than what I have now because it's more efficient. I have 155 mains, he's got me dropping down to a 135. Thats with a 904. I guess the dyno will tell all.
Always remember to be yourself. Unless you suck. Then pretend to be someone else.
