When I remove the end-caps and hand-rests, there is only a 5/8 inch hole in the end of the chrome (clam-shell?) grip. Compressed air would only go inside the handlebar unless I can find some type of adapter to cover the whole 5/8 inch hole. I'll be working with your tips and get it done someway.
Thanks again. Good forum. Lots of good help!
TEN MINUTES LATER:
They are off and intact. Thanks for your suggestions.
First of all they are a real bear to get off and I hope you don't want to reuse them. I sprayed some WD40 a little at a time with the little tube provided on the can at the switch end then used a coat hanger wire to open them up a little and then sprayed some more WD40 until it finally came free. However there was so much glue on mine that the rubber in the grips was ruined. Kuryakyn doesn't sell the rubber for the non clam shell grips.
Actually, they were glued securely at the upper end and not much glue on the other part. I did pry the little rubber pads aside with a small screwdriver and squirted some lacquer thinner through the holes. Got them off and they are still usable.
I will auction them off for our charity fund at our next Chapter meeting. They look new, except for the glue that still adheres to the upper end.
