Does anybody know of a supplier for the original type 4 ring pistons to fit the 600CC range. Or in desperation of a firm that can manufacture to order very small numbers. I am working on the restoration of a Model Z and want to do all I can to make it as original as possible.
Thanks
Chris

Thanks for that Steve but as far as I can fathom the Model Z used 68mm pistons and my poor thing has already be overbore by 0.100" to take BSA golden flash pistons.
