Hand Grips

Why don't you want to glue it on? You can buy grip glue which is not permanent, as superglue is, and this is the normal way to fit the grips, I know some use the wfes hairspray too. Brake cleaner spray can work too by making the rubber stickier, also makes fitting the rubbers easier.

 

I changed the grips on my SS for Triumph Barrel grips and the originals were a very tight fit and took some getting off!
Take your grips off, clean the bar and the inside of the grip with brake cleaner then refit them. They will always be easier to push on than pull off. An old trick I've used years ago with grips is spray the inside of the grip with hair lacquer which acts like a lube to get them on and like glue when it dries.
