Hello All, I have a 1991 Ultra 27k miles, stock. The question I have is I have some SE slip on mufflers coming for it, is there anything I need to do once I put them on the bike? Thank you for your help on this.
Install then take it for a spin. you may need to move up your needle a spot or 2 + main jet 1 size larger..you ll know this by how it feels w/ ridding. if u had free flowing ex before u may need 2 do nothing

Have you done anything about the breather side? If that is still stock, you might get away with changing out the cans without having to retune the carb other than maybe a little tweak on the idle mixture screw.
But having said all that, if you haven't already, why not consider a full Stage 1 with the new cans and a freer flowing AC setup? The SE air cleaner kits are a good option. With these two changes, you will likely have to increase the slow speed jet to a #46, and the high speed to a 185 or so (assuming you have the Keihin CV40). Check these out on tuning your carb:
