When I got back in into riding about 10 years ago, after an absence of about 20 years, I was really into being seen, so I installed a Kisan modulator on my Harley. I did get stopped once in Oregon and was told they were illegal, but that was way back when modulators were still a fairly new gadget. I didn't get a ticket, and I tried to tell the officer they were in fact legal in all 50, but I guess he didn't get the memo. I wrote his superior once I was home. I don't ride the Harley much anymore, and have not been much tempted to install a modulator on the FJR, though after reading some of these posts, I may reconsider. It was also my experience that once in awhile, pylons would pull over and let me by on my Harley, even when that was not my intent. I think most people are aware now that many motorcycles have modulators and are not LEO's.
