    Are you planning on racing this ski? Just curious? There are a couple of rules associated with "updating & backdating".

    I am not aware of any changes to the 2008 model that inhibits the gas in the oil, i.e. I am not aware of any changes to the craft that will resolve the gas in oil issue. Someone please educate me on what Kawi has been done to the 08 that will cure the gas in oil issue. Thanks

    From my findings so far the machine is running leaner then an 07 with a different ventalation set up.

    The seat is also different to aviod water seaping in around the seat.
    The Ventatlators are cut off and the ECU is different with a different part number. Red paint issue resolved and the exhuast is a tiny mouse hole with only one waterbox.

    More comming with lots of photos.
