I PM'd JGTurbo and he has gave me alot of useful info to take into consideration, 1st of all i am going to make a steel plate that will be bolted to the head, making this just a little easier! I guess it will sort of take the form of a header at first. Im going to be making measurements on the weekend to know how long the new steel intake ports can be. in this situation is longer or shorter better? i was thinking each one will be in the 4 1/2 to 5 inch range? i dont know if the length will change anything. but for now i am searching for the right carburetors. i need some sort of calculator to find the best possible A/F mix for every single cylinder separately. if there's six, and i still want some fuel economy, they must have to be quite small! im thinking even smaller now, like even dirtbike carburetors.
I had six 38mm Mikunis running on the Locost for a while. It revved nicely, but it never returned to a stable idle the way it should have. Just too many little levers and connections and they wouldn't go back to the same location they started. Also, you have to use a fuel pressure regulator to drop the pressure to about 1~1 1/2 psi or the stock pump overcomes the needles and seats.

wow thats really fow fuel inlet pressure only 1 1/2 pounds? or is that how much lower it has to come from stock? and yes i belive the throttle linkage will be tricky. I wonderif theres any way to tighten up the throttle springs on the carb's to make them recoil a little quicker

most motorcycle carbs are gravity fed...thus high fuel pressure causes problems.
