I am a new Harley owner of a 03 wide glide. And i'm looking to add a some more power. it already had v&h exhaust and a high flow intake. I'm kinda new to carburetor's but I now you can jet it but is it worth it?

 

If it hasn't been done yet, it's worth doing, yes. You will see gains, but without other mods they will be minimal.
A good 2 into 1 pipe will liven up the bike. Cams, bore, etc. will really wake it up.

Oh ya, congrats and enjoy.

 

He beat me to it, cams, throttle body, shaved heads, larger bore, it goes on and on...

 

Once you start modd'ing it you will never stop. I speak from experience. Rejetting and cam's will probably net you the most gains for least amount of money.

 

thanks, I'll look into that.
