Source for oil resistant clutch plates
« on: 15.04. 2019 06:56 »
Hi everyone,
A friend has left me with his 1927 FN M70, which has a badly slipping clutch.

I understand that BSA plates can be modified to fit. Don't know what model.

Because this is a wet clutch, the plate inserts need to be non slip in oil.

Who can supply BSA plates using this type of insert?

G'day richard.
I thought Surflex friction plates would handle the oil. *dunno*

Cork is the answer. Good wine corks cut oversize then placed in boiling water to soften. Push them is and clamp between two flat surfaces to dry. I use perspex sheet. If you have the facility you can true them up on a lathe with a very sharp tool once dry.

Chambrier in France (https://chambrier-pieces-motos.fr) sell bonded cork plates for clutches that you can easily cut yourself.
You have to email them as the plates are not in their catalogue ( it only shows ready cut ' pastilles' for different machines)

Not on my T110 they can’t.

I picked the friction compound off them and glued cork mat on in its place.
