Even with tyga pipes on mine i ended running 124 main jets with an air box and that bike never once gave me any trouble. Thats 2 sizes down from stock. Wayne also ended up close to that although i sent him some 130's plus just to be on the safe. Its better to start off way to rich than way to lean.. as our piston thread shows... NB tyga 300 i just cant get jets big enough to stop them seizing lol
