I just installed the Big Radius exhaust on my 2012 wide glide with the stock O2 sensors. I read somewhere on the forums that I do not need to tune the bike, I can just reset the ICM so it "learns" the new exhaust. If this is true, how do i do that? Thank you!

 

It will learn on its own, no need to do anything. You won't have the big change you'd get if you changed the air cleaner too anyway.

 

yes and it will be as lean as before... i would suggest an AC and some sort of fuel managing system,, PC3 At the least
