Clutch not working lt77

[nickm]

Just tried to get the clutch working on my Westfield but it wont release.Bled the slave numerous times and it seems to work ok when removed.I fitted standard sd1 clutch parts but now wonder if they are right.Could anyone tell me what length the pivot post should be and the dimensions of the lever?Any other suggestions would be very welcome as this is driving me nuts.Thanks,Nick
