I have a 2010 fat bob, only things different in it are the headlight, tires, and cycle shack slip ons. When I put it under hard acceleration there’s this sound that comes from the rear(sounds like left rear) that sounds almost like when a steel cord starts tightening up real hard. I can’t figure out what it is. Any ideas?

 

How long does that sound last? When was the last time you checked the slack in your belt?

 

It's called "Wind".

Start with the rear wheel alignment and belt tension....
