haha, thanks justin, but he's right. all i'm good for is lip flapping bs.
anyway, the carb and intake that is on a stock a55 are both 14mm, and so is the port in the cylinder where the intake bolts up. with the right pipe and air cleaner/box, you can get 45 from a stock a55 easy. if you want more, you'll have to go to a bigger carb, intake and get to some porting.
there is nothing at all wrong with wanting to build your own intake and "show others how to do it" (i'm sure they really need you to show them, lance).. but you were asking for people to help you research how to do something that's already been researched and done. that's pretty much the only reason you got any grief to begin with.
