I was wondering why there are so many threads and posts about regulators/rectifiers. Then, as I was driving to work this morning (about 4:15 am) I suddenly saw my headlight become twice as bright as normal, then return to normal after a few seconds. This happened several times but then stopped after about 15 minutes. It doesn't take a genius to figure out the culprit. I'm guessing I should be proactive and replace the R/R before I cook my battery. I just bought the 1995 bike last year with 43K miles, I always use the switch to kill engine but cannot say what previous 2 owners did.
