I need some help. I recently dumped my bike in the sand and broke my acerbis rally brush handguard (right side). I took the bike home and started to take the handguard off. Without thinking, I unscrewed the allen bolt too far and ended up leaving the bottom portion of the bolt assembly in the handlebar! I know this sounds really dumb, but I cannot get this piece out. I've tried vacuming it, dropping a magnet on a string, duct tape on the end of a screw driver, tipping the bike on its side and tapping the bar with a hammer. Once again any help or advice would be appreciated!
