My headlight seems to have an issue that I have been putting off looking at while I get more familiar with the bike. When at an idle, the light seems pretty strong, but fluctuates slightly, and when I give the bike a little throttle, it dims considerably. I nosed around in there looking for any obvious loose connections, and also checked the battery connections, but everything seems o.k. there. Would replacing the sealed beam bulb be a good place to start troubleshooting, or does this sound like more of a problem with the rectifier-regulator? I'm going to dig into it tomorrow, but if any of you have any insight or experience with this problem I'd appreciate any input!
