I've been scratching my head working out how to get my left grip off the bars so I can just whack it back on when I get the new ones. It looks tightly attached - do I just heat the rubber and get it off that way - then reheat it to get it back on ? (thinking like airhoses on an aquarium) or do I just cut it off with extreme prejudice and get a new one ? The main dilemma is I wanna get the instrument block and clutch lever off.
