I've just purchased and received a pair or Acerbis Rally Pro brush guards for my 2004 kdx220 to replace the stock ones. The handle bars are stock and I went to mount them last night and could get the piece that clamps on the bar to work but what about the piece that goes into the handle bar itself on the end. What came with the kit seems too long it only goes in about half way. Anyone have any experience installing these? Thanks!
