anybody think i will gain any power from a 1985 Honda ATC 250 carb or will it even fit in the stock intake boot. anybody have any specs to how many mm's it is. its a Keihin carb/ or would this be better Keihin PWK carb from a middle 90's KX250. 38mm or would that be total over kill for my motor i plan on having it ported and the head reworked soon.
