[82 XT125 cutting out over 1/2 throttle]

Main jet was clean and clear. Turned out to be one half of the stator assembly was bad, had evidence of melting the epoxy coating of the windings. Replaced with a used one , runs great now.

Just to please everyone I will pull the carb for the fourth time and check it out again. Again I will remove the main jet and run a torch tip cleaner through it as I have done before. I will try to take pictures to show also. OK lol I even have a filter in-line before the carb. This is why I wondered if it could be an electrical issue.

I know the jets are all clear and clean. Removed them and used a good carb cleaner along with compressed air to make sure all passages where clear. Does kinda make sense about the battery.

I became the new owner of a 1982 XT125 that is in great shape. But it cut's out when ever you go past 1/2 throttle. Runs awsome other-wise. Have pulled carb an cleaned, idles fine, checked fuel tank , lines , filters, all flow fine. Acts like lacking gas , but I know thats not the case. I do have an issue with the lights though. If I turn on the signal lights with the brake on , the signals won't work right and the tail-light dims. I have tried by-passing the little green thing bolted to the frame neck on the right side with a red & white wire and lights work fine then. Don't know what that part is nor can I find it to buy. Also does it need to have a battery to function properly ? I just can't afford to spend much on it replacing parts that I don't need to. Any help would be greatly appreciated.
