The thing is 'why change it for nothing?'. The s10 engine emits all sorts of noise and I wasn't sure if the CCT was failing and contributing to all the noise. From the video of Checkswrecks it sounds like a failing CCT emits a very distinct, loud metal-to-metal noise. This isn't the case with my bike (yet!).tomatocity said:If you put this much time into thinking about... change the CCT and you will never have to be concerned again.
