I’m replacing the friction plates on my 1963 A65 Star Twin. It’s a four spring clutch.

I ordered the plates and immediately noticed they have a much bigger surface area than the old ones. See pic. But they fit really nicely and slide on easy.

The problem is that the new ones are much thicker than the old ones. I can only fit five plates on before the stack becomes too thick and I can’t get the spring plate on.

Any ideas?

PS - how do you post pics on here?

Hi Barry. I fitted one of those 4 spring clutches to my 1971 OIF motor.I found a 7 plate set of plates,added a Alloy pressure plate from SRM and now have the sweetest clutch you could hope for. No more grinding into gear-oily snick when cold. Also replaced all the springs and cups etc .with New T140 750Bonnie ones.Cheers.Beer now.

The 4 spring used 5 friction plates as standard.
It is the better clutch.
Check the centre doesn't rock about before you assemble the plates.
If it does the spider is worn and the clutch will slip+drag.
If you have one thick steel plate it goes on first, some had one some didn't.
Using that thick plate means you can't get all the plates in with a 7 plate kit..
