Assuming you are using two stroke engine oil, the pump is pumping too much into the gas. DO NOT use motor oil in the gas. If 2 stroke oil is being used, then get a new pump, fix the one you have or disconnect the pump and mix the oil with gas when you fill up. Four ounces of 2 stroke oil per gallon of gas equals the standard 32/1 fuel mix.

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

it will rev cause it is sucking air where the oil pipe used to be. the tube will be close to the rubber intake, if not on the intake itself

Yes , time to top up the oil, Yamaha just want to give you plenty of notice, cause nothing will destroy the engine quicker than running out. I would be topping it up as soon as you see a bubble in the window.
