I had the same issue with throttle side grip and their super quick dry glue. I was half way on when it dried. I carefully took a super thin small long electronics screw driver and worked it up in between the grip and throttle tube breaking the super glues hold. With the screw driver sill in place creating a small gap I sprayed some soapy water up in the gap. Let is sit a few minutes and was able to twist the grip the rest of the way up onto the throttle tube. Once on I didn't even have to wait for the soapy water to dry the grip wasn't moving. It'll have to be cut off if ever removed.
Left side was glued on with their slick super glue and slid on the bar way too easy. I expected it to come loose in time but after 2 months both grips are working fine and have not moved.
