Fix My Hog Answers Harry,  Great kit if you are not afraid of high rpms remember that by using the stock heads that is and always will be the limiting factor for flow, you need rpm to pull air/fuel through the small port and by the small valve. Best bet is to save some money and buy a set of buell thunderbolt heads and then you will be riding a better mouse trap. Snap the throttle and wind up on your back. Make sure the boring is done 100% correct or you are wasting time and money, rings will not seat and the blow-by will kill all power. Mikuni carb is also a great option; stock ignition with rev limiter is also a problem not enough advance soon enough. Need good fuel or additive, a lot of options so, do your homework. Don’t just shop price, you may be disappointed after a few rides.    Wrench Safe, FMH
