I'm doing a top-end job (its first) on my 92 XR600R. I've torn it down and sent the cylinder and cylinder head out for reconditioning. I went to look up how to measure the cam chain wear and the Haynes manual procedure was to do the measurement while the cam chain was fully installed. It's a bit late for that now. Is there any other way of measuring wear? eg measuring the length of a specific number of links? Mike.
