Fourtrax 300 4×4

ad the idea in my head for sometime to build a 4×4 quad with a 450 sport atv motor on it for the power and the option of a manual clutch I tossed around the idea of using a chain drivin 4×4 scrambler but I really want to use a fourtrax 300, any one have any ideas of how I could pull this off? Any options or ideas are taken into thought
