Mystery Power Outage 84 R80

I put a new battery in this bike about 1,000 miles ago - Odyssey AGM.

I bought the bike recently and batt that came with quit on me a few hundred miles into custody. Good news is I was at the house when it Jumped it off, hooked up and verified charging at 14v so decided that it sat too many MI winters untended and replaced.

No warning yesterday 7 hours into an 8 hour ride bike stalled when I closed the throttle coming to a stop sign. I'd been riding some of our sportier two lane roads for 45 mins, not lugging along. There wasn't a drop of juice in the thing - I mean flat. About 10mins before stop, gps started 'lost external power' which I thought was jiggle but turns out I was below voltage spec. Idiot light is operational but never chose to glow.

Given some of the NGA goat trails I'd enjoyed, the interruption could have been much more of a pain in arse. Connections good. Kick start turned it over but no ignite. So the sun was going down and this town was closed except for Awesome Bill's Pool Hall, eateries and gas n go. Nearest source for new 12v was a big box 10 miles away so I found a wrecker and waited a few hours.

Was running PIAA 510s for some of the day + head lamp ~ 165 watts.

Gave it a 2 hours of 6amp charge back at the house and cranked right up.

Service manual says charge should be 14v making 280w / 20 amps with charging starting at 980 rpm. Regulator spec'd to deliver 13.5 to 14.2 at 5,000 RPM.

Observations this morning - batt at rest 12.85v, 900 rpm 12.5v. Climbs to 14v by 2250 rpm and maintains to 6,000 rpm.

Possible that regulator or diode has an issue with heat / use?

It did get up to 14.1, just below when I snapped pic.
