Cam Chain Tensioner

Bike in question is a 2015 F4 RR. I noticed a louder than usual clicking/knocking sound lately. It sounds like an extra loud cam chain. Bike only has 8000 miles so it's a bit premature, but maybe the F4 has a known issue with cam chain tensioners going out? I made a video to show what it sounds like so hopefully someone more familiar with the bike can identify the sound. Video is from the right side of the bike.

I'm not sure why the link isn't working. Video is uploaded as unlisted, but as long as you have the link you should be good to go. It looks like it's working for some? Edited the original post to embed the link directly. That should work for everyone now.

The noise does not change if I pull the clutch in. I've tried revving it higher in neutral, but my engine/exhaust sound drowns it out. Can't really tell if it gets louder with revs.

Vid works for me, too. No particular experience with those engines, but it does sound like thereís some rattling going on. If itís obvious enough to you to take notice and apparently increased over time Iíd follow your instinct and take it to the doctors - on a trailer/truck! Or pull the cover and inspect if technically inclined.

There were issues with the gen 1 tensioners, with heaps of info on the forum. Don't know about gen 2 though.
Does it go away when your fans cut in? This has been related to the alternator gear in the gen 1. This is something that I've been dealing with on my '08 312R recently.
The centre bolt on the alternator Cush Drive was very loose.
Some possibilities anyway

MV engines are not the quietest machines. I don't really hear anything in your video that sounds different from my 910R. The early 1000 F4s had defective tensioners (machined too small in pivot pin area resulting in breakage) but I can't recall any mention of problems since.
The design is the same as used on many other brands. Pretty reliable.

You could (if you want to) remove the central bolt from the tensioner, extract the spring, insert a small drift punch or other rod, and push the adjuster inward to force another "click" in the ratchet. Do that while applying rotating pressure on the crankshaft to put maximum slack in the chain. That may quiet the chain a bit if cam chain noise is what you hear.

At the same time, if you find the tensioner moves easily in and out when the spring has been removed you will have found the problem.

I used to be fast....now I just dream about it.
