Screaming Eagle

:moped: I have a 2004 Sportster 1200. I am thinking of switching to the Screaming Eagle pipes with the Screaming Eagle air cleaner. Do you have to rejet the carb with this setup or can I leave it stock and rejet at a later time?

More airflow on both sides may make it necessary to enrichen it a little, but it's hard to tell. The dealer should know from experience with your model. If not, just get a set of plugs and do a plug read. Most folks have all 3 done at once, but in the end, you have to do a plug read to see if it's correct.
