I purchased the GIVI hardware and the Twisted Throttle rack for the f6b. The instructions say to remove the OEM brackets, taking off the plastic on the tail end if replacing the existing rack. The holes line up with the OEM brackets and the Twisted Throttle rack. Is it necessary to replace the brackets? I am not sure how to get the plastic tail piece off. Since the holes line up and there are spacers, I'm not sure why the brackets need replacing. Thanks in advance.
Edit: I have discovered that the bolts on the Twisted Throttle rack will not fit with the OEM brackets, as the diameter is smaller. Now I have to figure out how to take off the plastic in the back. Off to youtube. So I can't find out how to remove the plastic below the luggage rack. Anyone have instructions on how to do this?
