get new short hubs with American bolt pattern , use 6" wheels . I rum an old SKM with an open 100cc , these chassies like a lot of HP .
move your wheels to .025 from the frame , loosen every pivot point on the kart rear bumper bolts so loose I have to zip tie them from viberating out . Nerf bars should be loose [ move 1/2 " ] . my seat is even loose . work with the spelling I work at night
