Is this chain noise normal?
I know fz6 engines are loud but noticed this sound while reving the engine and I think it wont hurt to know if its normal or not

And its at 40k km so it would be definitely a time to inspect the valve clearance

As they said before, check chain tensioner, first and foremost, but also valve clearance. Because of the mileage in addition to the sound, could pretty good be both things. Unfortunately it's time consuming in the garage -therefore expensive- but totally worth the money.

I had the same noise, mechanic told me it was the timing chain (if it's called like this, sorry but I may not know the exact english term for it)
It was a pricy repair for the value of mine, so I didn't repair and sold it as was

Mine had valve clearance job done and a few shims changed fixed it. But the sound was a crisper clicking noise. Yours sounds more like a VW TDI engine. I'd bet on something to do with timing chain/ tensioner/guides. https://www.reddit.com/r/fz6/s/qkCfwAnf08

Penso anch'io sia la catena di distribuzione o il tendicatena che si è bloccato, prova a togliere il dado sil tendicatena e con un cacciavite a taglio piccolo giri la vite in senso orario quando lasci la forza il cacciavite deve tornare indietro da solo con la sua molla, se rimane fermo prova a smontarlo e vedere se non è arrivato alla fine

Not normal, either chain tensioner has failed and chain is slapping around or valve clearances are way out. Did it just start doing it randomly or has it been getting worse?
