Hard to tell you if its a clutch basket or cam tensioners etc.
Get a screwdriver that’s long , place the pointy end to the engine and the other plastic part on your ear, see if you can find the real source of the noise. Then i will take a screenshot of the service manual that tells you the likely causes
Eg. sounds like AK47 on the front exhaust pipe right there but more at the top part, then it it likely means “valves need adjusting” (too lose cold, heat closes the gap a tiny bit as heat / cold have weird physics on metals) , just an example!
If you say “the middle exactly where it says “hyosung” on the clutch cover , ==> Check your clutch plates and your thrust bearings (if sounds change pulling clutch in or not etc ) , so you have to do a deeper dive if possible to locate the noise a bit more precise if you can.
