I've always understood it that factory jetting is usually pretty good until you start making mods to your intake and exhaust. With everything else factory, the factory jets should be good(?)
I suppose you could try it with the factory jets (mine has 116 main and 35 pilot)...I know the pilot is the factory jet size but not positive if the main was ever touched or not. If you're not happy with performance you can make changes.
Carb tuning is a dark art that I don't want to get too involved in! From idle air control screw settings, jet sizes, adjusting the main needle up or down...I'm a happy camper if the factory settings just work.
