The clutch noise is common. I just live with it. It is made of 15 M&M (peanut) sized pads.
The material is questionable in QC, and can melt if your clutch slips all the time, or you abuse it. There are expert bike abusers on the forum that can attest to that.
The pinion and ring gears also make noise. QC is even more questionable. I had to change a pinion out, brand new, because it was riding on the outside 1/2 of the ring gear. The tapered hole wasn't machined deep enough. They run thousands of these every day at the factories. Employees aren't allowed to point out flaws in parts to the boss. Not a lot of money is spent making some parts of these engines.
