Just got my F3S but in prepping it, the dealer forgot to install the cowling. They subsequently shipped it to me and it readily goes where the passenger seat was. It also came with some hardware to eliminate the grab rails but I elected to keep them on. It also came with two bolts about 2 inches long, two nuts encased in plastic, two washers and two aluminum cylinders about 1 1/4 inches long. I have no idea what purpose they serve and the limited documentation I got from the dealer makes no mention of them. Any ideas would be appreciated.
