Engine Grinding/Clicking Noise -- IMSB? (VIDEO)

I am not expert enough to say what might be causing this (several things come to mind but I won't speculate), but that noise is not normal. I'd shut it down and have it trailered to a shop for a professional opinion. At this point, you want to avoid a catastrophic failure that could damage a lot of engine components.

Seems risky to run it, even to provide an audio sample to us. If there is an internal part causing the noise and it hasn't fractured it may be repairable.

I would have a good indy take a look.
