The multi-pin connector just after the main fuse has been a known source of agrevation as well. It will head up, and stop connectivity. May cool off, then resume working. Key switches go bad also. Kill switches go bad. Kickstand switches go bad. Clutch switches go bad.
Please give more info when this is occuring. Does the headlight come on at all when happening? Dash lights? If so, which ones? etc...
On my personal ride - the 85 - the clutch switch is being intermittant, as sometimes when I turn on the key, everything on the bike seems perfect, headlight lights, dash lights light, but ZERO happens when the start button is depressed. I quickly giggle the clutch switch, and all is right with the world. No more problems the rest of the ride, but it may, or may not, act up again the next time I turn the key on and go to start the bike.
