At around 5000k and above, my turn signals are incredibly bright, as is the indicator on the "dash," and they flash super fast. I'm assuming this is too much voltage. I swapped both the regulator and rectifier with identical parts for a defunct cb360 in my garage, and it performs exactly the same. Could it be that the regulators from both bikes are toast? I read here somewhere a suggestion, to a guy complaining of the same problem, that he may not have wired the regulator correctly. Can anyone tell me what colored wires go where? Right now the three wires from the regulator plug into connectors attached to the exact same color wires. Apart from burning out light bulb filaments, is it hard on the bike to run it with too much voltage output?
