I'm finding oil on the ground beneath my 05 PX150 after being parked for a while but its not coming from the oil drain plug area. Its accumulating on top of the muffler mostly visible on the spare tire side of the scooter and dripping off the muffler. I think it may be less if I turn the fuel valve off but not 100% sure.
Any ideas how to investigate would be appreciated. The bowl that the carb sits in is dry. I removed the bolts that hold that black plate on beneath the seat but something down lower obviously needs to be disconnected before the tanks can be removed. I didn't see any oil around where the oil sight glass connects to the oil tank. I don't see evidence of leaking on the engine side of the scooter.
