A little bit of carb cleaner applied to the adhesive will dissolve it enough to get them of without forcing them. It will also make getting the grips off really easy (spray under-twist-slide off). Apply new adhesive to the back of the heaters in the form of double-sided carpet tape or grip glue and you're set.Is there a good way to install Symtec grip heater elements so that I can re-use them if I change bars?
