hmmm i just put "the hands" on it and gave it a good twist. well, several good twists, and it came right off, undamaged. try that first.

 

My dealer says they just cut the left one off and have to replace it. However, if you want to try to save it, I've had a lot of experience with glues on guitars and would suggest that you try a hair dryer (think minutes, not seconds) or wrapping a heating pad around it for 20-30 minutes and then try working it loose. If it works, once you get the initial "break" from the glue you may be able to just use muscle power to get it off or you may only be mable to move it a little. If it stops on you again, go back to step one and re-apply the heat. Normally, I'd say the heat is not worth the time vs. money that you dave, but since these are 100th anniversary grips, they may have sentimental value for you.

 

Well, I tried lighter fluid, thin bladed screwdriver, air, brake cleaner, carb cleaner and got the left one off, but the throttle side would not budge. I finally had to cut it off and there was so much glue under it I ended up using a wire wheel to clean it up enough to take the new grips... I don't think the factory puts that much glue on the grips so hopefully you won't waste a couple of days like I did....
