i have a 1998 fatboy i put on new wheels and a chrome rear pulley now it squeaks i have adjusted the belt tight ,loose,left and to the right and i even sandblasted the area where the belt runs to remove the chrome ,rough it up a little the only thing that works it dupont dry wax spray its good for a couple hundred miles or till it gets wet i never had a squeal before the new pulley also it does have an air gap on the sides between belt and pulley thanks

 

i had a pulley squeak but it turned out to be the belt guard was mounted between chrome rail and the plastic guard. just changed the order and the problem was gone.

 

Try spray silicon and check to make sure there is no rubbing.

 

is it at certain speeds? same freq? R U sure its the pulley or belt rub?

 

it squeaks under power the loudest and chirps when you let out of it not sure if its the belt or pulley the only thing that i changed was the pulley using the same belt just my luck it could be the belt and just started at the time i changed the pulley but at 180 bucks for a new belt hard to just change it to see if that fixes it thanks for your response

 

what pulley did you replace it with? you know they changed the width for 07 and newer

 

I believe that they changed the belt tooth contour or shape back around 07 when they went to the narrow belt.
So it may be that you have an old style belt and new pulley, or vice versa.
The fact that there is a gap on both sides of the belt and spray wax makes it go away leads me to wonder if its not just the belt teeth rubbing on the pulley slots.

There is a guy who "fixes" pulleys by cutting the teeth off and replacing them with a polly ring that's supposed to be virtually indestructible, lets belts last longer and is noiseless.

I have seen his stuff advertised in the back of American Iron and one of the magazines did a test and gave them high marks for it.
