I created this 3D model based on a Go-Kart that my good friend and I had actually built. The Go-Kart that we’ve built had a Yamaha 360 engine bolted directly to the frame. It had a 1 to 1 gear ratio. It was so radical that we could not get past second gear, it was way too fast. So, I created this 3D model using a Harley Davidson engine.I cannot even imagine what speeds could be obtained with this beast.
