I have a 1999 883 Sportster. I have drag pipes and a hypercharger air cleaner installed. I need to know what jetting i should use. Stock jetting on the bike is 42 pilot and a 160 main. I know everybody is saying to go to a 45 pilot. I also picked up a 1988 sportster needle. Is a 45 pilot good? Should I bump my main jet up too? Also how many turns out on the air/fuel adjustment screw? Thanks for your help
