Why is oil coming out of your motorcycle exhaust?
This could be caused by a clogged PCV valve, worn internal seals, or worn valve guides. A clogged PCV valve will pressurize the engine internally, which force oil past important seals into the exhaust stream. Likewise with worn seals, oil simply leaks out. Worn valve guides makes it possible for oil to seep down the exhaust valve into the exhaust stream.
