Yep it sure would....I think he was joking
Glueing them is the correct procedure but it does leave you in a bit of a fix when you want to get them off ...get it....Fix
My suggestion would be to get a syringe ( such as is supplied from a printer ink cartridge refill kit) or any other means you may know of, and try to inject something like white spirit between the heated grip and the bar. On the throttle side you wont have a problem if the two bikes are the same or use the same throttles, but obviously you will have to do the same if not.
Another option is good old Google, a weath of information is out there.
