Need Engine Readjustment If I Get A Thinner Size Air Cleaner?

[Gregmm]

I wanted to get more of my foot on the brake pedal when I do brake but, my air cleaner is too wide. If I do get a thinner one, would I need to remap, adjust engine, etc. Thanks
I have: 2005 Road King

I think there would have to be quite a difference in air flow before you would have to re-tune. I've ridden my 95" 2002 Road King EFI for very short runs without the air cleaner on, ust to see if there was a difference in performance, and I couldn't feel any difference at all. I think in most cases the exhaust plays a bigger part in your air flow then the air cleaner. If I were you I would make the change and see how it runs. Worse case you'll have to re-tune. Just my two cents worth!
Good Luck!

an easier solution is to get some floor board extenders and a drifferent brake pedal.
