Is this a rod knock? Video attached. 91 Club Car Ds

Can anyone tell me if this sound is a rod knock? If not, any ideas what it is? I just bought it for $1,500. If it is a knock, should I replace the motor now, or just drive it until it needs to be replaced?

Sounds roddy to me.

The crankshaft often gets damaged when the rod bearing fails. There was a place that would build up and re-grind the crankshafts on those. Springbok probably knows, so hopefully he'll see this post and chip in some info. He knows lot about the old KF motors.

Nope that does not sound at all like a rod knock, just sounds like garden-variety clutch chatter. Both my carts make that noise at times but it's not a big deal. Mine do it sometimes on decel when I'm driving at higher speeds.
