Snow X pistons

[lonerider1]

Has anyone had an issue with the Snow X p-tec/ e-tec 800 piston upgrade breaking circlip's? We had 1 fail and took out a top end. Upon inspection it was fixing to break another 1. It seems the wrist pins are thrusting to the mag side, as both pistons were beating the clip groove out of the piston. Not bashing or looking to bash. Just looking for answers. We've installed these in 4 other engines. This sled had about 1k miles after install.
Thanks

I put them in my 2013 800 etec summit but only have about 5-600 miles on them so far. I hope they hold up or I won't be happy.
