For the gearbox oil, it doesn't. But I put a stick and checked it, it seems ok. Should it be full to the top?

Hi, Airhead. Please tell me how do I check the gearbox oil. I know where it is found, but how to check? The hole is very hollow. No, it doesn't smell of fuel. It seems only oil. My father says 2-stroke oil is so smelly and its normal. Is it?

Hi dt502001, yes I'm using coolant. I think its of green colour. And what "plug black" are you referring to? Spark plug?

Hello Everybody There is a problem in my DT50 and I think it is quite serious because it is an oil problem that can cause damage if left untreated. I feel that the engine is pulling extra oil. The symptom started when one day I was repairing the indicator lights. I started the engine and left it for about 20 minutes while accelerating from time to time because the battery was dead. However, after a while, the engine stopped unexpectedly, making a suffocating sound. I thought that the engine suffocated from too much fuel and acceleration. I tried to kick start several times but in vain. I managed to start the engine by making someone push the bike and after 4 or 5 attempts, it started, but on the point of stopping again. After a few rounds on the road, the bike was now ok. At that time, I could't figure out the problem. However, during the last few days, my father went to work with the bike. He said he managed up to 80km/h. But he at that speed, when he came home, there was drops of oil spilled on his shirt. This happened 2 times and then, we started to be conscious about the problem. I don't know from where this oil comes from I recalled the incident that happened to me and now, I think that it was OIL that suffocated the engine and not FUEL. I know too much oil can be disastrous. So can anyone tell me how to fix this problem? The smoke is also VERY smelly and sometimes white and abundant. I have uploaded a photo of the oil pump. If there is something there, screws, etc... from which this can be fixed, please tell me. Thanks in advance

I think the screw is blocked... maybe due to contraction. When the engine gets really hot, I'll try again, hoping that the little expansion will loosen the screw easily. I don't want to apply excess force because the material of which the screw is made is really soft. The head is getting damaged quite easily, as is the case with the other screws nearby . So bad.

Yes, you were right, here are 2 screws. Now which one?

Ok thanks YPVS TONE. I will post a photo when I finally open the cover...

Thanks for your reply. Here is a photo for reference. What should I unscrew?

Hello Everybody I have a DT50 year 1990 bike. I need to change the tachometer cable. But no matter how I pull the cable out (the end near the throttle cable), it won't come out. Can I just pull it to remove the cable or are there any screws to be unscrewed first? The speedo cable was straight forward. Just needed a pull... Please help me :/
