If I put reeds and change jets, what will I gain? will it help on top end? or will it hurt my blast off ? will it be worth spending the money. Is the gas mileage going to hurt. I have 1999 225 ho on a 1996 javelin. 5900rpm, 6 inch jack plate, 26 racker going to send my prop to mark. I mix my oil and gas have a new fuel pump, took oilier out. Runs 69 with load and 72 by my self I like to get a little more out of the motor any suggestions.
