It could be the exhaust valve. . I learned about valves a bit now and looked some things up. Going to attempt this. But the thing is. I can’t seem to figure out this engine. It says 165fmm-p on it. But I can’t seem to find much or any info on it. I know a lot of them changed the names of the engines of something. But everyone who seems to have this kind of engine has a 5 gear. This is 6 and fuel injected. I have no idea what kind of gasket this thing uses. Would fee more confident if I knew the actual engine name. Here are some pics to maybe help? Any info would really be helpful. I can’t find shit https://drive.google.com/drive/folde...8MKAqrvK7AwRaH
Yeah, it's pretty common knowledge here that the cheaper Chinese bikes come with a Chinese plug, and it needs to be changed out immediately. Same with valve clearances. It doesn't matter what the engine is, just get the exhaust valve gap wider. Say .06 - .10 mm. Yours is probably set at something like .02 mm.

There are two Top Dead Centers BTW, and only one TDC is useful for setting the valves, the one that has both rocker arms loose. AKA the compression stroke. On some engines it is hard to get to that one, because as you rotate the motor at the flywheel, it will lurch forward on its own and pass the TDC you want. The solution is to not use a ratchet wrench, instead use a breaker bar in order to have control of the engine spinning.

You can also use a normal box wrench of the right size as a breaker bar, if you have the adapters below to insert into your socket. Any hardware store should have them. A lot cheaper than a breaker bar, if you don't have one of those. Here is the exact same product, far cheaper at HF.
