I haven't changed the clutch cable on mine yet.I have a new one to go in but I've done loads on my other bikes over the years and use the same old trick on cables.
I disconnect at both ends but don't pull the cable out.Then I tape the new cable to the old cable using some masking tape/adhesive tape.Then pull the old cable up through and out of the top and guide the new cable through.That way I never mess up the cable routing.
The Cable routing on my old CX500s could be a real nightmare.
