We have covered some of the most insane DIY projects here at RideApart, from a cooler-kart build to an electric three-wheeler. But something just seems sketchier, rawer even, about this 180 horsepower CBR 1000 swapped shifter kart from the folks at BUM (Building Ugly Machines).
For starters, the kart they picked up on Facebook's Marketplace is a rust bucket. Even with its wildly underpowered 212cc Harbor Freight Predator engine, it seems like a bit of an accident waiting to happen.
