Hotgrips unstuck

[Jamieg285]

The hotgrips were already fitted to the bike when I got it.  I've discovered that the throttle grip isn't firmly attached, and is moving.  On a relatively short run, the grip can have rotated 90 degrees to the throttle handle, requiring 'reverse thottle' to rotate the grip back to where it should be.  It's also able to move left-right a bit, which has led to sticky throttle.


Any suggestions on the best way to resolve this problem?
