    Gp1200/1300 questions

    how do i know if i have a 1200 or 1300 gp?
    something went wrong water is getting into the hull and after 1 1/2 of riding engine starter to make funny noise and it docent sound normal did a ct and got 120,60,125 the middle piston is way low is it shoot? can new ring do the trick? or i need new piston,boring,rings etc? need help on this one since i am new to the 2 stroke deal, i was running premix premium with 10g gas to 1 qt oil.

    i have a 2006 and it is fuel injected.

    when the engine does turn on it sound like a bunch on nickles in a can.

    2006 efi would be a 1300r need to pull the head to see how bad the damage is. Excessive noise could be piston slop, however I am leaning towards bad bearings. Do not try and start it any more till u determine the damage. If it throws a rod bearing u will ruin your case.

    so finally had a chance to get to this what needs to be changed? and could this may have been caused by water going into the cylinder?
