Go-kart Blueprints Does Anyone Out There Have Blueprints For A Tough Tough Go-kart Frame??

Does anyone out there have blueprints for a tough tough Go-kart frame?? - go-kart blueprints

I am looking for plans and the dimensions of a robust 2-seater go-kart chassis. My plan is to put a 1400cc engine from the old bike on it. Ohh, and a chain driven machine, if that's any help .... Thanks
