I've got a 2005 FJR that I purchased used and it has the OEM heated grips on it that no longer work. I have beenlooking for instructions on the installation so I can reverse them for removal but can't find them anywhere. Do these grips have their own throttle sleeve, or do they slide over the factory one. If over the factory sleeve then I can just try heating them up and removing them (but they look like they have glue on so may have to cut them). I'd rather put some more comfortable grips on since the heat doesn't work and don't want to use the grip buddies or grip puppies.
