My bike is leaking out fuel and it is leaking oil from the bottom of the crank case these are two separate problems. the fuel i can't tell where its coming from but its over some of the cooling fins, there's some unburnt fuel especially after i run the engine hard. its all the way around the the fins on the cylinder and on the seam where the case gasket is. the oil is seeping out of the the bottom of the crank case, its pretty consistant that after i run the engine there will be a hanging drop of oil on the screw at the bottom of the crank case. I dont have any idling problems, and the engine seems to run fine, what is going on here?
