I have read the posts on this site relating to S3 sounds but I still have questions... Here's the situation: I know the S3 has a noisy engine and components and I am used to the sound. Recently however the bike has become noticeably louder. Specifically, I am talking about the clicking sound that comes from the left side of the bike. Normally it sounds like a little ball bearing rotating in some metal container but for the past few rides it is A LOT louder. In addition, whereas it used to be somewhat rhythmic (in tune with the RPMs) it is now sporadic. This noise is so loud that when I open the bike up on the road (remember this is with a helmet on and with 80mph wind howling by) past 6 or 7k RPMs it sounds as if there is a loose part on the bike somewhere. I know the S3 is noisy but do I have something to worry about? Any ideas about what could be going on?
