Thought ya might be interested in this. this weekend they blocked off a couple city blocks dowtown and had shifterkart races. this was the first time i have seen them. man they fly. top speed for the day going threw the trap was just over 90mph and that was just on one block straight. most were running 125cc rotax motor on race fuel. they looked like a blast. lots of spin outs but couldnt catch any on film just happens to fast. but there was lots of straw flying
