    Help me bring this 2000 1100STX DI back to life

    Bought this on the cheap today. 2000 1100STX DI. It is my first DI engine, with a few carb'd pwc's under my belt. I am sure I will have a lot of questions in the future as well.

    I did some initial disassembly this morning. Looks like the rear piston was TOAST. I am not sure exactly what happened. Crank case is full of oil... not looking forward to getting that out of there while lifting the block of the hull (I presume I will be lifting the engine to inspect the bottom end).

    1. Think I can re-use the head seeing how the rear spot looks pretty bad. Maybe get it blasted?

    2. Any ideas as to what would cause this? The old owner said that the last time it was used they went out and lost power suddenly and could hear the something was wrong with the motor. It has not been used in years. 3 or 4 at least.

    3. Any way to test the fuel injectors to make sure they are working?

    4. When I first got it back I checked for spark but holding the plugs against the head and turning the engine over. COuldn't see spark, but these plugs were very old. Any other ways to check spark? I suppose I could check the resistance of the ignition coils, but if those check out I am still unsure of what is wrong and cannot produce spark.

    I haven't seen any writeup for a 1100 DI rebuild anywhere so I will try to document what I do the best I can.

    for an engine that failed, the cylinders look and feel OK considering. I thought I would be boring these out, but maybe not. I need to give them a better inspection tomorrow and maybe hone them.

    Hope you didn't pay much for it! At least there should be a lot of parts available because so many of these things have electrical problems that make them uneconomical to repair.

    The top of the piston looks very clean. I'm thinking water intrusion did that. Maybe head gasket or warped head.

    Are there means to test these electrical components? EMM, fuel injectors, other recommendations?

    I would believe water intrusion... water box and exhaust was mostly full of water. What's tha mean going forward?

    Water box and exhaust will have water in them, especially if the machine stopped suddenly. You should check the crank on the bad cylinder, it may have spit out bearing parts.

    Kawasaki diagnostic software.

    Anyone have the software? Perhaps I could ship the parts required to you for inspection?
