Okay, good:thumbup:
These came out of my 'used' snowmobile. The owner before me didn't like to warm things up before revving the sh!t out of it and it destroyed these pistons. I know you probably can't see the pics very clearly, but there is obvious scuffing on the sides from the pistons expanding faster than the cylinders. Two of the pistons expanded so fast and scuffed so hard that they broke the pins that locate the (gapped) piston rings. One of them is stuck in the top of the middle piston.
Again, sorry for the low res. pics., I wish you could see these better.
