93' KTM MXC 300 Oil Leak

Anyone know of a common leak on the right side of the engine. I can't tell if its comming from the joint where the Cyl meets the case or one of the bolt on flanges.. Any Ideas where to check or how to tell where its comming from.. Yes I have cleaned it well before looking. Thats kinda the problem the oil is too clear and the bike is too clean..

Thanks
Jeff
