I had the same problem, pain going across my shoulder blades was intense after just a few hours in the saddle. My fix was to install 2" pullbacks. This made all the difference in the world, now I can drive all day without the pain I used to get from reaching too far for the bars.
Who's pullbacks did you go with? If HD, do you have the part number? I’m getting desperate to change out the Klock Werks. I’d love to find something that actually brings your hands back.
