Installation of the Fast Scooters 48V "Overvolting Kit" on my Razor MX650. This is part 3, which focuses on the top speed results with the kit installed combined with the factory 11tooth sprocket and with a 13tooth sprocket change. This is supposed to maximize the power you can get out of the original motor by running / adding a fourth battery.
