Last summer I installed Kuryakyn grips on my '08 650. As the instructions said, after removing the old grips, I sanded down the ridges of the plastic throttle tube (not sure of the proper name) to the point the new grip slid on with resistance. Unfortunately, when I did this I did not check to feel how the throttle worked and, after glueing the grip on found the throttle grip would turn but, not freely return on its own. It acts and feels just like my 400, on which I've installed the Cat O-ring as a throttle lock (those who've done it know exactly what I'm talking about). I would like to get it to working right. With it glued on, will the grip pry off or, can I expect to trash it in removing it? Also, what will this do to the throttle tube? If it is ruined, is it an easy thing to replace? I was hoping it would loosen up over time but, I've probably put 5k miles on it since, with no discernible change in the feel of it.
