I just got some Acerbis hand guards for my 2010 XT660r. The Acerbis plug has an M8 threaded bolt; the Yamaha bar end has an M6 threaded bolt.

To fit the Acerbis hand guards AND use the bar ends I need to remove the standard plug and drill out the bar end to 8mm. I have removed bar ends from other bikes but these yamaha ones have me stumped. I can't budge them, trying to knock em into the bar didn't work either.

Any Tips? They feel rubbery so lots of loob might help.
