Kart Honda GX270 *11hp* - Tuned

Our tuned "Bumblebee" with the wonderful sound. At springtime/summertime we will test it the first time, of course we'll make a video of the first test run.
(Kart: 270ccm Tuning from 9hp to 11hp with harder valve springs, tuning intake air-filter by K&N, without engine speed limiter (rpm), longer exhaust manifold and a 390ccm carburetor!)
