Bike starts dying at low RPM once it's hot

How long has it been since you've checked your valve clearances? I don't believe it has anything to do with a thermostat, and I doubt your electronics are to blame, either. It could also be a vacuum tube that is getting soft and kinking off when it gets warm.
FIRST thing I'd check is the vacuum and vent hoses. If they are OK, I'd go to the valve clearance.

Like mine, maybe your bike came off the production line a little to the tight side of the tolerances and now the effects are finally showing up?

OP - I have a 1979 Honda trail 50 that had the same issue. It would start up fine, run perfect the first five minutes until it got hot, and then it was done with. It wouldn't fire up and would only run if I had the throttle near wide open.
At first I thought that it was a jetting issue but as it turns out it was a valve clearance issue.

Hi there,
I'm running (or not) into the same problem, i always had issue. It degraded this year.I purchase a new rectifier\regulator,waiting for it in the mail, but as the bike warms up the current stop flowing threw until there is not enough current provided to run the beast.I'll let you know if it really does solve my prob.

There is also a ground issue with the electronics piece everyone is talking about, it's symptoms were more of a high speed miss but if it was allowed to get worse it could present as a non running issue. The fix was to add a ground wire. I haven't had any issues myself so I can't be any more specific about this mod.
