I just bought my son a 2014 Tony Kart kid kart. He is still quite small, and needs pedal extenders to reach the pedals comfortably. The problem now is that Tony Kart has a completely different way of constructing their (throttle/brake) assemble. The round bar used for the pedal is a 10mm solid round bar, as apposed to the usual larger diameter hollow bar. On top of that, it is also bent at a 90 degree angle at the ends. So you cant even use a simple slide on extender. Is there any particular solution for this problem?
