Hi there seams to be a lot of stuff on the Facebook page about adjusting E and A series Villiers clutches,( I couldn't add a PDF file there) so here's an article from Motorcycle dated April 1964 which should answer all the questions, the real key to the problem is the shims fitted under the cap (they are like piston rings) these actually adjust the preload on the clutch springs, new plates require a thick shim and worn plates may require no shims, if you put new plates in without any shims you end up with a heavy clutch, as the plates wear the clutch may slip, this can be remedied by removing shims.
With this in mind you can add or remove springs and end up with a clutch that is light and still grips, I hope this helps. Cheers Pete from the Antipodes
