Cam Chain And Sprockets?
 

Not wanting to derail this thread reading it got me thinking...

If you replace the drive chain you should replace the sprockets at the same time as the new chain will wear quicker without (I have tried this and can confirm the theory). However if you were to replace the Cam Chain should you replace the Cams (as the sprockets are not listed separately)? And if not, why not, I assume the same wear theory as applied to the drive chain?

Also replace the crank as that's got a sprocket as part of it...

But, the camchains are a different design of chain, which spend their life with splash lubrication of (relatively) clean oil. So don't need replacing so often.
