Big Bore molydenum performance pistons(forged)?
I found some snowmobile pistons and I know that my ski is water cooled.These pistons are molydenum coated skirts like the kind I would use on my streetrod engines and have a small dome.I just wanted to know the difference between the 2 cycle pistons for water cooled and air I guess.I thought some sled engines were also water cooled (closed system).These come in 72mm which is what I want and I am no stranger to machine work for more power as far as shaving heads,gasket thickness and big bore jobs.These pistons also have the same pin size.Please advise.

The polaris MSX 140 uses the same pistons used in the polaris liquid cooled 800 snowmobiles.And they also have coated skirts.
