After successfully building my first go-kart, I was eager to make improvements. Two weeks after completing the first go-kart I disassembled it and salvaged all the parts I could (the same 6.5 hp engine, computer chair, centrifugal clutch). I decided I wanted to be able to drive my go-kart off-road. I began sketching up a preliminary design and started doing research on vehicle dynamics. I decided to use a steering box (I salvaged from a golf kart) instead of the basic pitman-arm/tie-rod go-kart steering, I wanted independent front suspension (but didn't have the resources to make double-wishbone a-arms) and rear swing-arm suspension. So I started doing more research on off-road systems in use in go-karts and dune buggies. With a finalized design, I found some scrap metal, shocks, wheels, a lawnmower seat, ordered a 1" live axle (as well as a disk brake rotor and mechanical brake caliper) and started building the off-road go-kart. in a few months, it was finally complete, I made some basic modifications to the engine (removing governor and high-flow intake/filter) which noticeably improved power output. It worked great! I was able to reach a top speed of 50 km/h (increased weight and increased power cancelled each other out) and my steering radius was great, but I experienced some bump-steer while on rough terrain (due to the single wishbone suspension and the steering system's relative geometry).
