hehe, my lil mini bike, popped the original tire so we put a trailer tire and rim on it, stock exhaust, modded to be a tad bit louder, have a cool exhaut, but the frigger won;t stay on, sooo i put the stocker on, open airfilter, this thing is ungoverned and fast, slow takeoff tho, it is fast as a stock hhonda xr100, its funnn! just need to make some hillbilly suspension for it, lol
