This may not apply to your bike but a lot of the smaller engine 2strokes can still run but backfire if they have one broken reed valve.

SOURCE: yamaha DT 125 2003 Main beam headlight keeps

i have well, had a very similar problem, my headlight kept going on my 1990 dt125r from 1990 to 2003 the engine is the same so i feel it may be the same fix, the regulator/rectifier stopped working properly and was alowying to much power to get to the headlight and blew it, i got a new regulator/rectifier for around £30 ish, you could tell when it went caus the higher you reved it the brighter the light got until it blew not like when it gets brighter from tickover, it was just proggesive and just kept getting brighter the more you revved it, hope this helps

servo valve sounds like it needs adjust or the power valve adjusting do you have a manual ?
