I redlined my 2000 zx6r when someone asked for a rev.

It stalled, then had this metallic knocking noise and sounded super raspy.

In the video it turns on and idles but it sounds raspy and there was a large pop from the exhaust as you can hear.

Could this be timing chain failure? Valve float? Pls help 🙏
