mine doesn't drip oil at all, as to the coolant sounds like your pump seal is calling for replacement

The breather tube from the valve cover ends right at the beginning of the flat part of the skidplate on the left (shifter) side of the bike. If that is the side where most of the mung & drool is, that is most likely the problem.:worthy: Seeing as how a Yamaha is neither British or a harley it shouldn't be leaking oil.:thumbsup:
