I have a stock carb on my 06 Streetglide with a jetkit, V&H ovals and Arlen Neww Big Sucker. Even with a 48 slowjet, it occasionally pops through the air cleaner and my gas mileage sucks. If I baby it, I get 31MPG. What are the advantages and disadvantages of swapping in a Mikuni vs. friggin around with the jetting more on the stocker? As far as future engine mods, I might do a 95"bigbore and cams, thats it.
