Hit up Durwood (member here) .480 CR cam, most any 2 into 1 pipe, ditch the plastic manifold, PV tune, 45+ mpg,    2020, 114", FXLRS, CR480, S&S 2-1 (harleytechtalk.com)
Roll on

That's pretty much it, these motors really respond to a cam change, good exhaust, air cleaner, and as important as the parts, a good tune.
Peruse the Dyno section, and especially the cam comparison tests in the M8 section by Fuel Moto and Durwood.
