If the oil leak is the one where the oil drips on the black plastic scoop on the right side, that's a given. I think we are all experiencing that, at least every rider I have ever met. It is nothing to worry about, and it does come from your breather box. Your tech should know this.
The breather box does seem to be a given. However I had to have both head gaskets replaced with less than 9k miles because of them leaking.
