    Pics of bent rod on GP1300R

    Hey Jim, here is the pic of the bent rod. I had seized the rear piston, so when they said I had a bent rod I had guessed it was the rear. Instead it was the front one. Luckily I sent the crank off for inspection, got it trued and welded. Crankworks did a great job.
    Interesting way of bending a rod, I thought they bent with the rotation of the bearing, not the opposite way.

    That sucks,but it is normal to bend to the side that is where the rod is the weakest.....Most cases this is what you will see or a bend and twist action..

    Well, wouldn't the top of my piston on the #1 cylinder have some kind of sign of hydrolock? The cylinder walls and the piston are prestine. There was no excess fluid at the bottom of the cases, just a little fuel and oil mix.
    Could a motor with a rod bent like that keep running for a long time or would it eventually fail within an hour or so?

    If you continue to run a rod bent as your is it will put too much pressure on the wrist pin and cause it to break or crack,also you are risking the damage of your piston skirt,etc....

    3rd cylinder is notorious for hydrolock. That looks typical.

    Surprised it was front.

    Carbs sit on floor of ski. Water either bounces off mid-wall, or get splashed up off coupler, combined with aftermarket flame arresters. The GPR is a "wet hull."
