cut em off. If you want to keep them you can try and use an air nozzle and try and work the grips off. Not sure if you could use a solvent or something on whatever glue was used. Your not trying to get the stockers off are you?
my blue grips on my 01 will fall right off if i pull the rivet. the black ones on my 99 are practically welded on. you got any extra grips around jeff?
