Back in the day, my best friend Tommy, got bit by the racing bug. He decided to buy one of those go karts and race it on the weekends. A race track was set up at Kadena Air Base, Okinawa and we found ourselves watching every weekend. This wasn't no Briggs and stratton. A Yamaha 100cc motor powered this little beast and 35 to 40 mph was normal. For anyone who thinks that you can't overturn one of these things I will tell you that it can be done. Tommy scared the hell out of us when he ended up under the cart after a roll in turn 3.
