I have a loaner puller I can send you if you don't want to buy your own?

They're ageing out... just old age, nothing more. After 40-50 yrs the enamel insulation is breaking down.
It's possible the regulator stuck at full charge, burning it out, but you'd see/smell signs of that.
It's a good idea to replace the regulator anyway, as it's just as old. Don't spend the big bucks on a Chinese knockoff that won't last long, you can make your own. Have a look here. https://www.xs650.com/threads/diy-reg-rec-5twins-and-jim.55842/
 
I ordered a puller, never can have enough tools. (G) Really good information on the regulator and rectifier upgrade.
More stuff to search for, but that's part of the fun isn't it? I still have three running Triumphs so this can sit till
I sort it out. Thanks for your help and I'll contact you when I'm ready to ship rotor.
 
Sure looks that way, I need to order some parts from one of the vendors on here and will include a rotor puller
in that order. Anything specific to look for that would cause rotor insulation failure? It does not look like
it overheated, no burnt smell. At one point this bike had hard bags with extra tail lights and a vetter
style front fairing with extra running lights. Maybe extra load over time? I plan on going over all parts
of circuit anyway, just looking for likely culprits.
Jim’s rotor rewind service is second to none. Every time I buy a 650, I automatically send him the rotor regardless if it’s good or not. EVERY stock rotor will eventually fail.

At the rate Jim is working there will come a time when he has all the XS650 rotors rewound and then what will he do with all the free time!
