Can you help with this knock?

Hi, its very faint in the video, and it doesn't start until you've been on the throttle for a while and it is warm. Also, after a while if the bike is just at idle it will fade away. Its not the clutch and doesnt matter if you engage the clutch or not its a knock not a tick.... and its sounds like its louder near the rear cylinder near the top. Im woundering if it maybe the tensioner is starting to fail, and the slop in the chain is making the knock? She goes like stink!... lots of power.

Any Help would be great! ... Its a replacement motor from a wrecker, I changed the oil at 400 klm and then again at 900 klm. I didnt ride it hard until the 900k and thats when it started.

Couldn't pick out the any sound of impending doom, though you might want to change the OEM CCTs to manuals pronto if you suspect something 'changing'.

I concur, no doom pending.

But if you are as paranoid as I, then buy a mechanic's stethoscope. Being able to listen to the inside of a running engine is money in your pocket. As you place the probe on the various external surfaces, your ear can pick out the internal components as they spin, slide, whir and click.
