If you have an air compressor, use a rag or something to make a seal around the air nozzle and blow into the opposite end of the bar you want to put the grip on. It will balloon the grip and slip right on. You can also take them off this way if they have not been glued on. You may be able to work something under the grip and get the glue loose and then use the air. Much easier than it sounds. The Rincon has a bolt in the end so when you remove it, there is not a very large hole to try seal as you blow into it.
