    Sorry to hear of your bad luck. With that much damage, a second hand engine is advisable if you can find one.
    It sounds like it started with a broken rod, and the rest is a result of that.

    it started in your jet pump !!!!!!!!

    upgrade the jetpump to 310 series shaft and bearing setup

    Hey thanks for the info.
    I stop the engine failure only by the update on the stock and the jet pump wave of 2011?

    Or there are other problems such as pistons or connecting rods? Valve springs? Oil cooling?

    Which oil would you take? 10W40 according to Kawasaki I find inappropriate. in my Tubofahrzeugen I've always driven a 10W60 because the oil temperature is not entirely irrelevant.

    10w40 is fine, no other failures all internals are good.
