I admire your ambitions, but $200 to get this thing running under power with electric powertrain, I don't think so. Not sure what the Kart weighs as it sits, but guessing an average weight including you sitting in it would have to be around 200-250lbs, right? To push that kind of wieght around even on flat level road you would need something worthy enough to get you moving and make it move well enough to make it worth the price of admission. Anything less than 25-30 mph would get real boring pretty fast. Finding a good BL motor that size will more than likely cost you more than $200 by itself. Even a solid brushed motor from place like Harbor Freight would cost you at least $100. Then you have to find a spec worthy control system for the size of this project. That alone will cost you more than the $200 which you intend to budget under.

In order to do this even half way right you would more than likely have to invest a grand to build up the electronics and powertrain to a point that would make it run fairly well and actually keep it running more than a couple of days without burning it up. Just look at how much it costs to create a BL HPI Baja 5b that can run 30-50mph? You would be better off finding a good karting type 2stroke engine with enough power to push you around in the 30-40mph range and even then stying under $200 would prove to be a pretty tough task. Just my 2cents.
