    As some of you know I have been having an intermediate oil leek into my crank. It would load up and burn off the motor oil. the bike would run fine for a few more miles and then load up again. I finaly had it. went to my dealer and they told me what to look for and yup my main seal on the clutch side was in backwards, from the factory. easy to change it out and the part was only $24.

    We have a quick cheater method to check this with out doing a total leakdown test .
    Roll the motor to BDC,then run a piece of fuel line from your crank case vent into a cup of water or soapy water.
    Wrap a rag around your muffler tip to seal a air blower and blow about 15lbs of air{just guess} and if bubbles come out thats your problem.This really works for quicky diagnois when strangely fouling plugs alot for no reason.
