I cannot figure out how to remove the top piece of plastic just below the luggag rack? The piece on top of and just forward of the tail lights. I purchased the twisted throttle rack and have to replace the oem brackets, but can't figure out how to get this piece off to access the brackets. I have a trip coming up and was hoping to be able to mount a GIVI top case. Thanks in advance.https://d2k6fukgv6pr2f.cloudfront.ne...0000_002sm.jpg
