    2007 RXP Burning Oil

    I have a 20007 RXP that is consuming oil at a very fast rate. You can see the oil being burnt through the exhaust as it smokes way more than any 2 stroke. You run the thing at idle for 2 minutes and the low oil pressure alarm is coming on. I have also noticed a lot of unburnt oil in the intake. Any ideas? maybe the supercharger oil seal has gone bad? I am just not sure if this would cause the oil to be burnt so quickly.

    I forgot to mention that there was a good amount of fresh oil in the vent valve coming off of the head going back into the intake.

    Sounds like you have way too much blow-by from bad rings.
    This also happens when a air filter is completely clogged.

    Check compression and go from there.
    If the compression test fails, then do a leak down test, so you know what your failed
    component is.

    Are you using the correct oil?? The wrong weight oils tend to be an issue.
    What type and weight oil are you using?

    How many hours on the ski?

    sounds to me like you have a piston that's damaged causing blowby

    Those are good #s but they could be incorrect due to the oil in the cylinders.
    Oil in the cylinders are going to give you higher #s.
