Rich or transoil?

I have dropped 10 main jets and my bike is still running rich (I will take care of pilot after).
Its getting better and at high rpm its clearing but Its smoking a shit ton and a good amount of oil comes out from the exhaust. Im starting to be afraid its transoil. I will upload a video so that you can see for yourselves. Please help.
Note that my engine is completely rebuilt. Seals and gaskets are new.
The bike smells like my polaris snowmobile and ive heard that if it is transoil it should stink.
 
Does it have the stock Keihin PWK carb? Did you happen to soak the carb to clean it? Have you checked that the jet block gasket in the carb is good?

Stock carb. Stock main jet is 185 and Im at 165 and its still not good.
No I did not check the jet block gasket
 
White smoke can also be caused from water vapor or coolant in the combustion chamber.

Be careful with leaning out the main that many sizes trying to address the issue, especially if you are riding the bike on the road. Smoke may become the least of your worries.

You are absolutely right but I mean I cannot even clear the bike out. I have heard and noticed myself it can be caused by water so I need to double check that its not leaking, even though everything is new
Wish this was easier but it is what it is

If it is caused by a rich condition, it could also be that the needle seat in the jet block is worn (ovalized).

I mean that is probably very uncommon though? What is the most probable things I should start out with? Check water in cylinder and change jet block gasket?
 
He's not wrong about needle jet wear. But check is just take a decent photo under light and zoom in to look for any ovality.

Easy check. But I'd put money on your main jet being dangerously small and something else being wrong.

I will go back on main and search for the issue cause it cant be the main anymore. I ordered a jet block gasket. Comes tomorrow and hopefully will fit. Ill check for ovality in the block and needle. Im also going to check my water level. If these things doesnt work, I dont know what will
 
Did you repack the muffler? Soupy mixture in there burnr on smokes like a Vaper.

Need stripping apart and burnt out inner, easy with map gas cylinder Outside.
The perforated core can be quite thin on original.

Its repacked and cleaned. Yes, smoke is problematic, but also that its running extremely rich even though Ive went down too much on jets.
 
Finally finally finally. I think it might have been the jetblock. I must admit, getting a new jet block gasket here in Sweden in a reasonable time for a good price (I wanna ride Now 😭) is hard so I wrapped the gasket In RTV. It works
Holy shit the 125 goes like crazy! My other EC125 goes nowhere as hard. Its insaneee
Thanks for the help guys, would never be possible without you.
Now in going to fix the brakes, pass inspection, and then mount supermoto wheels
 
Get that RTV out of your carb ASAP! RTV breaks down in gasoline and it could really plug up your carb making it almost impossible to clean out.
