I liked karting better when garage time was mechanical adjustments and cleaning instead of chemistry. All sports evolve and grow -- football players are purpose-built bulldozers instead of "average guys" now. F1 cars are gazillion dollar upside-down airplanes instead of cigars. And karts are growing in weight, cost, and complexity. But we should probably not lose sight of the fact that karts were designed as a fun weekend diversion that was intentionally simple -- as an escape from the car racing world. I'm not sure that mission creep toward the car racing world suits karting in the long term. Part of the appeal, IMO, is the simplicity. If you want to bend your brain trying to learn setups, go buy a late model. There also seems to be a growing segment of the sport that just wants to show up and race. For that segment, the LO206 would be a perfect choice. I'm sort of surprised that a track down here in the SE hasn't really tried them. They're far better than the cheater's paradise of Predator motors, IMO. Of course any class that's not policed is a cheater's paradise, so I'm also surprised that there's not more tech, especially when you can make more money racing karts than a 4 cyl. hobby stock. Oh well. I'll go back to lurking.
