Yes. The grip is going to take some work to remove. I would recommend an air compressor and a blow-off tip shoved between the grip and bars to help coax the grip into sliding off. That, or a can of air (like for cleaning a pc keyboard) will do.
Or you could squirt a little wd-40 between the grip and bar. Just a little goes a long way. I've used this to help grips slide back on as well, but use just a very small amount.
