MT-07 CP2 engine rattle

Hi! I know about the usual timing chain tick/rattle in the CP2 engines.

However mine has some weird rattle at about 5000/6000RPM when releasing the throttle. It's very hard to capture, since it only does it when driving, not when stationairy. Also doesnt always do it, even when driving. I think I captured it in the recording here. It sounds like its coming from the front of the engine.

Have you guys heard ever heard this? The bike rides great, it has done about 15000 miles and has had its maintenance. I usually don't worry about these things but am planning to sell it soon so I would like to know if I need to fix something first.

Went by my local garage but they weren't able to hear anything at the time. Thought I'd consult the experts here.

Thanks!
