I have a 2012 Fat Boy. I've made it cosmetically appealing and now I wanna enhance the engine and performance. Only thing I have done is put on BIG RADIUS' and tuned it. I am new to bikes and not sure what can be done to bikes to add HP,Speed etc? I'd appreciate any advice. THanks.. ROB

 

Good place to start is cams.

 

I agree with Gommee.
Be honest with yourself about how you ride and go to various cam manufacturer websites and peruse their cam specs. Pick the one that best matches RPM range you like to ride in.
I prefer Andrews for instance. For your 103, the 48 for low to mid range performance, or the 57 for more mid range to high end.
Lots of threads and info in here to keep you awake for weeks and your head spinning.

 

How much money you got?
Cams and big boys head work if you're on a budget.
Mackie if $ isn't an issue.

2012 is the 103, correct? How much $$$ do you have to spend is the question. The other question would be how is your ego when it gets dumped on, they're a lot of mean scoots out there. Some flaunt what they have and then there is the sleeper.
My suggestion is spend a little and just cam it, ask yourself o you really spend a lot of time doing trip digits or is the low to mid range cam more to your likening.


I, too, like Andrews and I would prefer the low to mid range. Ride the scoot, enjoy it.
