First ride of the season. Started off nice. Fully charged battery cranked the motor over nicely. Ran well for most of the ride until I began to get random misfires. Bike dies in the middle of a four lane road. Nursed it home by pulling the headlight fuse. Colorful language ensues. Have 8.5 volts at the brushes. Rotor ohms out at 3.9 ohms, still in the bike, brushes pulled, measured by touching the rings with the probes. Kick starts ok. 11.8 volts and dropping, regardless of revs. I am thinking if my regulator was toast I would not be getting any charging current, and if my rotor was toast, I would get infinity or very low ohms. Sill, 3.9 ohms isn't great, considering it is all new windings. Any thoughts?
