a freind of mine gave me a frame to a racing go cart. its got hydrallic disc brakes and good tires but no motor. i was looking into maybee getting into this sport. i can generally do most of the engine building my self and all of the fabrication. i was just curious if anyone knew what kind of inspection or test that i would have to pass. i live in phoenix so i would probably race some sort of south west circut. and if anyone had any pointers that they could pass along. i am planning on using a 2 stroke dirtbike engine, atleast for the timebeing. any info is welcome.
