Sounds like a piston ring to me. Was there any smoke coming out of the exhaust at all? And the sound was it like a loud tapping sound? If so then i would definately say a broken piston ring.

Dropped valve ?
Broken cam chain ?
Holed piston ?
Small end problem ?
Big end problem ?
Throwen rod ?
Broken rod ?
Broken camchain tensioner ?
Broken camchain guide ?

Any of the above in any combination or maybe even something else I can't think of off the top of my head

Take the airbox and exhaust off and shine a torch up in there you should see the valves............if they are still there.
There might even be a few bits of valve in the airbox/exhaust.
If it has broken something you looking at a compete rebuild or a new engine
