I use to be able to get four wheeler and dirtbike grips off by getting some wd-40 and attach the straw to it carefully roll back the grip or slide a small screwdriver very carefully between the grip and the bar just don't try to pry it any you want to just make enough room to get the straw of the WD-40 as far in there as you can and spray it down good then slowly start twisting it back and forth as you work it off the bar. Or if your not interested in saving the old grips then bust out the razor knife, just don't cut your digits off in the process!!
