I starting leaking oil on Sunday while at a mini-moto. There was oil residue on the top of the cylinder and down the sides. There would be enough at the end of a 10min session to leave a few drips in the floor. The skidplate and peg mounts were covered too, my catch can was also full. Today I checked all nuts and bolts on the motor to double check and all was up to spec. I also changed the oil to make sure that there was exactly 1qt of oil for next time. Any ideas??
