I needed to remove the mounting bolts to allow me to pull the left radiator just a little bit outward on my 2003 to access the wiring where it comes from the front of the bike. No real problem, just some broken mounting/zip ties I wanted to correct. The 6mm special nut that holds the rear of the radiator to the frame broke in half as I loosened it. The outer part stayed with me, The threaded inner part fell into the frame.😐. At least it’s encased in rubber. Any way, I need the special nut now. I can’t get it before next week. I had a small group ride I wanted to take the RC51 on. I have other bikes, but dammit! Anybody have a different method of attaching the radiator to the frame other than the “special” nut as Honda calls it? It is a 6mm rubber nut, a bigger version of the rubber nuts used to attach the windscreen if anybody is wondering.
