Foretrax engine knock

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 ?

^^^^^ agree with Helmut... if it's a knocking, and turns out to be the connecting rod bearing, be looking for a lower end rebuild in your near future.... hopefully you'll get lucky and it's just some valve lashing your hearing.. but that is more of a fast ticking sound.... good luck on whatever it is...
good possibility it is the valves tapping... not sure on your model if you have seperate valve covers or not.. but the first thing I would check is the valve clearance/valve tappets... someone here will have a better idea on how to check them on your bike. if that's not the case, it may be the cam bearings are worn...
