I just got the HMF pipe and I installed with the drop in K&N filter and NO air box mods. They told me to use a 155 main. does that sound right? This bike isnt as easy to jet as others I have owned so I was hoping to get close on the first try.
If you dont have to worry about noise forget about the quiet core insert. The insert makes it as loud as the stock pipe. Without it it idels at like 108db witch it LOUD but what I have learned from my dad riding Harleys loud pipes save lives!
