I still want to see one with a pull-start.

Oh F'k...IMO either the wet clutch has come apart or she's lost it's rod bearing. Better not run it any more until she gets pulled-down.

I cant believe it ran as well as it did.  I'm horrified, but a little impressed too...  Grab a picture of that will you?

If it is a heavy knock consistent with engine RPM I would say 99% sure it would be a big end, only way to be sure is to pull the cylinder off.

It was the crank the bear was shot

Only case of knocking CFMOTO was when the main bearing shells had spun.
