oh and a little offtopic but whats the legality or w/e on gocarts? (michigan) anyone know off the top of their heads? save me some time looking it up

I know that B&S and Tecumseh engines rev to 3000-3500 rpm stock, but can push out close to 7000 rpm with some modifications. And the 6 HP Tecumseh engine we used on the chopper was like 150 cc...not as small as you would think. I have no idea about the legality in Michigan.
