I had KOR work over my engine. Here are my mods. I will be ordering a full CT racing pipe and silencer. What should I do about the carb. Right now it's stock with different jet for the fmf fatty. The fatty was on when motor was stock, and has not been put on since the KOR work has been done. Should I just put in bigger jets, or get a bigger carb? If I should get bigger, what size and brand. I ride mostly on mx track
