you will do fine with stock box and dyna coiils. dont touch the rev limiter, you will float it and blow the gas out of the carbs and do damage to it. besides, even wit the blower, you aint making squat for hp after 6800 rpm. still picks up a couple mph but aint making enough to write home about. 3300 to 6800 is the monster hp spot for these things. Mine is a lil different, tho I cant rev past 7200 before hp tails off to nothing. and with tat 45mm mikuni, you will run outa gas above 6800 anyway. prolly runing too lean as it is with it the way it is. just run it fat at idle and you will be fine. gas mileage will suck but, the bike will run like a raped ape. 1.75 lbs of fuel pressure is all you need. anymore and you will blow the float valve out of the carb. just a few tips for ya...
