twin engine conversion

hi guys, few of us have been getting into dirt karting and building out own karts. its just for frendly competion but very exciting. im not a professional racer or kart builder, lately i have converted my arrow bitumen kart into a dirt kart pwered by 6.5hp honda clone motor. ive decided to step it up to building a twin engine kart, to try and keep up. will post more pictures when complete and frame powder coated.
