Cam chain question
Hi, I've heard a ticking noise coming from my 2008 street triple. It's sitting on 40,000km, so I thought it's high time to pull it apart and check the tappets and the cam chain. The inlet valves were all in spec, and I have some replacement shims on the way for a couple of the exhaust valves which were just out of range.
From what I've seen here it seems likely that the cam chain tensioner is no good and is causing the ticking. However, when I put the piston at TDC to take the cams off, I saw that the cam gears were ever so slightly misaligned, as in the attached picture. Is this a symptom of a stretched chain, or is this because of incorrect tension from the tensioner? Not sure how many things I need to replace here - if it's the tensioner I'll just get one of those manual ones and be done with it.
