Sorry to resurrect an old thread, but I seem to be having a similar issue. My right rear signal began to flake out. I noticed this because the dash indicator did not work. It would stop working, then when I'd shut the bike of and back on, it would work for a little then stop again. Then the front right stopped working as well. Both right side flashers do not work at all, but the left ones work fine. This is true for both turn signals and hazard lights. Itrider - is this the same issue you had that turned out to be the relay? I'm going to try all of the simple stuff first - negative battery terminal, look for plugs, etc., first, but I'd like to know where to go if that doesn't help. As always, thanks for your time.
