1994 KX125 Running very rich

[85' kid]

So my bike is running very rich. It's not fouling plugs or anything and it feels great on power but it just blows oil out the exhaust, like an excessive amount dripping down the entire silencer. I run a 50:1 mix so I don't think it's the mix, the jets in there I haven't touched but the main jet reads #380 and the pilot reads #40, I don't know what stock is. I'm running a hotter plug in it, a 7 on the heat range instead of the original 9, and it seemed to have gotten maybe a little better but still excessive. It has a fatty pipe with a turbinecore 2 silencer with stock fiberglass reeds. I've used both Honda hp2 oil and Motule 2 stroke oil but both have the same effect, perhaps it could be the flash point of the oil? What would be the answer to the excessive oil being blown out the exhaust? And what might be a better jet combo for the pipe?

Looks like a 160 main jet is factory.
