Way too spooky. Had the exact same problem last month on the wife's Fazer. (R+G) Had to cut it off and buy a new left grip only from ebay �22. Remedy - Superglue the last inch of the bar on the metal nearest the switch block and then put superglue inside the grip in the last inch of the grip tube (nearest the bar weight end).

Also, when the new grip was put on it stayed on full heat blast, so I thought I'd buggd it again somehow but it turned out to be a fault with the controller (put it on an oscilloscope) . A new controller arrived the following week after a warranty claim.
