just wondering when in the mod list the carb should be up graded? i will have a 40 over 12:1 piston, web drop in cam, slightly ported head, full system, uni or k&n filter. would the 36 mm lectron be too much or even needed? darn near forgot- it's on a 250x

i would try to find a used 400ex carb. i think they fit on a 250 with minor modifications, but i am not sure. i know you could find one of these carbs for a good price.
