Motor died while riding this weekend. Will not start but will turn over. All the oil from crankcase was blown into bottom of airbox. I'm am going to check compression tonight, just trying to see what direction to go in.

Welcome to the forums. I don't think they made a 350 Foreman in '02. Are you sure it's not a Rancher 350?

Anyway, yes, checking the compression would be a good start.

sounds like its time for a top end rebuild just did it to my 02 rancher, cost me $ 350 to have its bored, new rings pistons, gaskets and valve seals. that is including the labor my buddy charged me
