SOURCE: hi there i have a yamaha dtr 125 thats smokes

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.

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

SOURCE: yamaha dt 125 red oil light has just started to

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.

No spark on yamaha dtr 125cc


Sounds like you are flooding the engine with gas. Put in a new spark plug then twist the throttle one time to prime the cylinder. Now get your hands off the throttle and give it a few kicks. Each time you twist the throttle the power valve gives a shot of gas. Too much can flood the engine quickly.

Hi there i have a yamaha dtr 125 "1990 on a h,plate my left hand engine casein is cracked at gear select,coul anyone tell me what year of casings will fit,ive seen a 1999 one will it fit,also piston and...


The bike is 19 years old. Caseings will be VERY hard to find. Suggestion; take the case to a welding shop and ask them to weld the crack. Teey will have a MIG or TIG welder which will do the job and the cost should only be about 20 bucks.
