I bought a newer tall boy seat and a driver backrest with mount. The tall boy fits just right, however, the backrest mount from Kuryakyn. It won't let the seat move back enough to secure it with the screw. I have tried to reposition the mount but I'm still 1/2" short. Seems the pinch bolt is preventing the seat to move. Removing the bolt will allow the backrest to drop to the lowest setting.
Any ideas how to fix this situation?
