thnx guys, but most lawnmower/waterpump engines rev only up to about 3500. which isnt too pleasing for me. as matt said, id much rather hear it running high rpms. i dont need to burn out or anything. i wouldnt care so much even if i had to push off running next to the cart if i have more top end torque. and high rpms. if i wanna start drifting with it, id like the high rpms. (and a manual clutch would help... is there a way to get a manual clutch rather than a torque converter or a centrifugal for a gocart?)
power to weight ratio with a 2 stroke or a big displacement with a big 4st. dont dirtbikes use anything as small as a 50cc? i dont know too much but say for example, a 5hp b&s lawnmower engine. whats the displacement on those?
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
