Sled is a 2011 800 Pro. Pistons got scored . Almost certain from snow injestion. Here is a pic of cylinder. I can only feel one of those lines with my finger nail barely. Took it to most reputable shop around here that I know off. He said it's not ideal but would work with no ill effects. Measured it and deglaze it for me. What do you guys think. Does it need to be redone.
