i put in a 330 main, thinking it might be to large, but my blaster runs great with it. i have full fmf exhaust, +3m vitos cranks, dual stage boysen reeds, k&N filter with open cover and just an outwears. does this seem right, or is there extran air getting in somewhere compisating for the large main?
