Put the first "real miles " on the F6 this past Saturday with a 450 mile ride. Every thing was great, gas mileage, comfort of the stock seat, ... . Except for a little soreness between my shoulders. I need the bars back 1-2 inches and up 1-2 inches. The Kury's look to be the ones, but it says that it also narrows the width 2 inches, which I'm not sure I'd want. Also, don't want to spend the $'s on the HeliBars. Recommendations and comments appreciated.
