went out and bought my new FAT BOY 4 pipe (duncan racing) they gave me a bunch of different jets the quiet cap and sparky for $535.00 OTD.(good deal saved about $70.00).anyway they recommend a 180 main ,45 pilot,and 3rd clip on yz needle. with my stock pipe(baffle out) i was at a 165 main,45 pilot(2 turns out) ,and 3rd clip on yz needle.(i have the cam mod and K&N).i was thinking a 48 pilot,180? main,and 4th clip on yz needle??? what would you guys recommend? i`m at sea level. i still have to put on the 15T sprocket .after that what else is there to do to get more power?
