I just adjusted mine to add bar ends for my hybrid flat bars. Remove the end plugs, using a small ( long) flat screw driver inserted between the bar and grip pry just enough to pour a small amount of alcohol into the opening. Slowly rotate the grip until it loosens and remove. Use alcohol to install the same way. It gives you time to rotate and adjust the grip then the alcohol evaporates. Don't know if this will work for grips installed with soap but it works great with factory installed grips and much easier than it sound.
