My rear CCT was playing up so I recently had that swapped for a working one. However there is still a slight tapping/ticking noise coming from it.

After receiving the, new to me, CCT I noticed that when fully extended it made a sort of tapping/ticking noise if you shook it but when fully in, no noise when I shook it. Found out that at around half way extended there is practically no noise when it's shook but when it's extended 5/8 or more makes the ticking/taping noise when shaken.

Now could this be what the noise is, that the tensioner has extended at least 5/8 of it's length out and the tapping I could hear when I shook it in my hand is the same noise when it's fitted on the bike? Could this mean I have a worn Cam Chain?

On a side note, not sure if it's just a placebo effect. I noticed on my way back from the garage after the new CCT was fitted that the bike felt as though it pulled a little stronger and generally felt a little smoother. Could changing the CCT have this affect?

I think the original CCTs can rattle so maybe it's normal, I'm not as boned-up on it as others on here. It won't make any difference to the performance, but a quieter bike always seems to be making lighter work of things.

The CCT rattle is normal on a Curvy.
You should be concerned when its through the rev range and quite loud

I'm pretty sure that as soon as you rev it the noise disappears. It's only at idle. If it's nothing to worry about then I guess it's time to store it for the winter.

a quick test is only slightly open the throttle when warmed and the noise should reduce.

Get it away for the winter and use the Pikey magnet until late February
