    1999 Xl 1200 Ltd build.

    Iíve never owned a ski, but always wanted one... so I bought this project with a blown motor.

    It has a mere 48 hours on the clock, and a hole in the block...

    . I,ve never so much as opened the hatch on a ski, nor understand how it fits together. The previous owner had pulled it apart enough to get some diagnostics on what went wrong and that,s where he left it.. so not only am I unfamiliar but I have a bit of a jigsaw at the end...

    Luckily the crank looks ok... with virtually no play in the big end bearing up or down... i note the smear of red rtv on the crank, and the cases have a good dose also...

    Test fit the cases together to see if they still sit well post welding..

    and they donít... itís about 1mm at the weld area.. iíll Check and double check, then test with the case bolts in to see if it pulls in before final assembly...
