having the same trouble, constantly adjusting the clutch and also quite stiff at times, tried a few cables over the years usually bought from wemoto, some are better than others but they all look identical.fitted new plates at the begining of the year as was having a bit of slipping when getting a move on. just ordered an OEM one from Fowlers...£57.01 about 3 times what i have been paying, will let you know how i get on.
