Just by way of a coda to this thread, I've found that the bite point gets lower and lower until I can't change gear at all, especially on a long run, like when I go to Wales This has happened to me a couple of times now, necessitating further adjustment. However, I think at last I've got it right. I wound the nuts right to the end of the master cylinder push rod and now the bite point is higher, and has stayed high for around 200 miles including some long fast motorway runs. I can leave the house with the clutch in perfect adjustment and after a couple of hours on the motorway I come off and struggle to make reluctant, notchy gearchanges on the exit roundabout. How embarrassing. I'm hoping that maybe it will stay put now. Even so, I haven't quite had the courage to put the little lid back on the pedal box, or travel without my specially shaped piece of wood that holds the clutch pedal down, in case I need to tinker with it again. The moral of the story is if you do this job yourself be prepared to experiment with the adjustment, and adjust boldly. If I'd wound it right out the first time I could have saved myself a lot of trouble.
