I got the same problem on my 07 Ultra. Everybody seems to think you will have to live with it. I don't think I will. Mine has 328 miles on it and it seems to be getting worse or I am more tuned in to it. Whatever the case. It is not satifactory the way it is now. I don't want to take the lowers off so I can't hear it. That is one of the reasons I bought the Ultra was for the lowers. I ride no matter what the weather is and that means cold or hot, rain or shine and the lowers help in that regard. I also think the lowers help with engine cooling. Mine is going back to the dealer and they can keep it till they fix it. If they can't then they can sell it. I have a bike that is not so offensive to ride. JMHO
