Hi there

You should not have oil leaking from the carby. If you have over filled it with oil, then it may be coming from the crankcase breather and then into the airbox, and appearing to come from the carby. If you have not over filled it, then the bike may have blowby problems with compression gasses passing the rings, and in a similar manner forcing oil out the crankcase breather. Not sure about the hole in the side of the cylinder... do you have a picture? Unless its pouring out, or gets worse, I would not be too worried. If you have over filled the oil, maybe time for an oil change to get the level right.

regards

I think water go in to the engine oil of my bike, what can cause that? crf450, 2004


Water pump oil seal is not a possible cause. Even if the water and oil seal were so worn out that the coolant passed through both seals the weep hole in the crankcase cover would have to be completely stopped up and sealed. In that case it would leak into the transmission oil not the engine oil. The coolant leak would likely be in the cylinder/head area.

CRF 450 Honda leaking oil through carburetor


it sounds like your valve/rocker cover to spark plug tube seal is folded over or something. My reason for saying this is, because the only place for oil to get into the plug tube is a bad seal to the cover or the spark plug isn't tight? and that hole is for expelling liquid so it doesn't cook the plug into the head
