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

Im looking for blueprints or dimensions for a VERY STURDY 2 seater Go-Kart frame. I plan on putting a 1400cc motor off the old bike on it. Ohh, and its a chain driven motor if thats helps any….Thanks

go to a welding shop or an atv shop to help you out or atleast point you in the right direction
