I just got into riding snowmobiles here in Wyoming and absolutely love it, am hooked definitely. Bought a 2001 Ski Doo Summit 800 151", with 3500 miles on it. Only rode it twice, once in the grass

and once on hardpack early in the season on the mountain (Snowy Range near Laramie).
Just would like any tips on my sled from members here. I was talking to a guy @ an expo that said the bombardier engine in my sled is famous for breaking pistons and grenading engine, any validity here? This guy recommended throwing in a set of pistons. I am a mechanic as a profession so this wouldn't phase me much as far as the execution if it was worth it.
Any tips on this machine would be awesome!! Thanks!!
