I installed Avon heated grips, and there was no prying anything, or blowing air into anything, or even any glue required. I just used an allen wrench to quickly remove the end weights, loosen the two set screws on the left grip, it slides right off. Open up the switch housing on the throttle side, remove the push and pull cables from the cam gear, and reinstall the new throttle grip. Not really sure why all the other fuss mentioned above is necessary if you get metric grips.
