I have the SE air cleaner and Reinharts and am interested in getting a Heavy Breather AC. My PClll is tuned for this set up. Will I have to re-tune when I go to the new AC? Those that have them, can you tell me if I will notice a power bump?

Nope, should just be a bolt up. I did the same thing , no problems.

 

Thanks Marine. Where did you get yours.? If you got it from a dealer was it $300.00 or is there a cheaper source?

I had the stageI and then went to the heavy breather,I saw a difference in POWER!I got mine from the dealer,but found them on E-Bay for less!

 

Fixxr, Did you re-tune or stay with your stage I tune?

 

I have an 07 SG with V&H slip ons and a stage I kit.... I JUST last month purchased the Heavy Breather from HD and installed it myself. I didnt mess with the mapping as I was told by the Dealer that as long as i was already set up for the stage 1, I wouldnt need to get remapped.
the bike runs great. Cant say that I was able to see any "REAL" increase in power.

 

I did not notice a power increase but it sure looks cool and was an easy install.

 

Thanks guys. While we were discussing this a Monkish from this forum offered me one he had lying around at a nice discount price. I'll be installing it as soon as it gets here.
Thanks all, What a great forum this is.

Ripper, I see the backing plate is chrome on your heavy breather, where did you get it or did you have it chromed??

 

I used the forcewinder because it was less than the Harley on my Deuce. Had popping after the install, had to rejet but that was with a carb, so it might make a difference.
