Greetings fellow sufferer, because of the cable being routed over the top of the cylinder head the heat generated gradually buggers up the cable, but it's a slow process so you do not notice it straight away. I renew my clutch cable every two years, and each time I am amazed how nice and light it is with the new cable fitted!. Nice quick job, just release each end and tie the new cable to the old one and pull it through. (From the top is much easier.) Regards, Mike.
