No compression at all

Why would my sons 1987 honda fourtrax 250x not have any compression at all? Im praying it doesn't need a motor. I think he ran it out of oil.

Easiest thing to do is pull the valve covers and see if one of the valves stays open when you slowly cycle the engine. That’s how I found the stuck valve on my ‘87. Cost me $400 parts and labor .
