My brother has a Kawasaki klr-650 enduro bike that he never rides and little does he know I am stealing his engine to put it in a quad frame cuz 4 wheels are better then 2. Now, my question is what frame could (or should for that matter) I use to install the engine in. I am building this quad with my friend who can weld so modding a frame wont be an issue. Anyone who can help me please do. I want this thing to have my heart and soul in it.
