Old topic I know. But my 2010 with 44,000 miles on it started making the cam chain noise even when warm. I'd be sitting a light and get the noise. I could increase rpm slightly and get it to go away. Over a period of a week it started getting worse. I've been commuting on it and working long hours and I haven't given the bike any TLC in the last few months. I checked the oil and nothing in the sight gauge

I added oil and it was 2.5 quarts low! I knew my valve cover was leaking a bit but obviously leaking more than I thought. After topping off the oil, the noise went away completely (except the normal 2 seconds after cold startup).
So I was wondering if I was actually loosing oil pressure. No indication on the panel but why else would the CCT start backing off in normal riding? Still runs fine but wondering if I damaged the engine at all.
