Here is my build: 2004 Road king FLHRI

My question is, is it worth it to buy a bigger throttle body and bigger injectors? I'm sure it is to improve air and fuel to my motor. If so what size throttle body should I go with? I believe mine is a 48mm stock one. Please give me detailed answer. Thanks so much....AJ

 

you'll do just fine with a "worked" stock TB...hillside or gmr can do it for you....on the injectors, use the SE 25deg ones for an 06 SG.....anything else will be overkill on both the engine and your wallet....been there on both sides with HPI & Marren inj, runs better with a bored out stock TB and SE inj for half the money
