Do you know that part of the frame is used to store the engine oil?

Where on the frame are you seeing the oil?

there is a hose from the top of the engine that leads down the shifter side of the bike and it will drip some oil,its a breather hose for the engne but oil also manages to be blown out there.If your rings are worn and getting excess blowby then it will be worse than normal,mine just had a new piston and rings and I still get some oil from the hose.
