Fair dos. The sticking choke is mainly the plungers themselves, mine builds up a bit of crap where the plunger seats so it won't shut off properly.

Default Re: Curvy Stator Issues. Bike cuts out

I have same issue with 2001 curvey, Alternator coils checked out, but battery and the bike die after 20 ish miles.
In the end I had faulty alternator coil, which shorted when hot, the lacquer insulation on the coils had small cracks which opened up to create an electrical short path.

After fitting a new alternator and cover gasket I had a problem with the bike stalling at junctions or traffic lights.
As the fuel tank had been moved to remove and re-route the new alternator harness it is common to trap the fuel tank breathers, which can also cause the bike to stall when idling, as in my case.

Interesting, thanks for sharing. I suspect your alternator was living on borrowed time, once any sort of short circuit starts in the windings they burn out fairly quickly.

Yes, the technical term F***ed.
While at Lucas some fair years ago now, the same used to happen to their alternators, mainly they failed due to the in built rectifier diode packs though.
I believe the hot oil can age the lacquer quickly.
