I have a 1999 ForeTrax 450 ES. Last winter I had it on the ice and reving it kind of high. It shut down and when I checked the oil it was really low. It runs, but now it has an engine knock/ping. What damage do you suppose I inflicted on it ?

Welcome to the forums. It's hard to say without hearing it run. Would you describe it as a knocking sound or a ticking sound? If it's a knocking sound, it's probably the rod bearing. If it's a ticking sound, it might just be your valves.

Yep, valve clearance or worn timing chain and tensioner. Tensioners on the 450 go bad pretty often.
