Ok so my mods included an a & d cool head with 20cc domes, fmf fattys with powercore silencers, k & n air filters bolted straight to the STOCK carbs, boyesen power reeds, bored .020 over with wiseco pro lite pistons. Ive read alot about jetting before posting this and from other similar set ups a good place to start for main jets would be 310's even 300's? just rather would start rich then to lean, but where i basically have no idea is will i need to adjust the needle and change the pilot jet as well? Just want to have a good starting spot with this and no harm done to my freshly rebuilt engine. Im 700 ft above sea level and ride from temps anywhere from 70-95 degrees
