Master cylinder boring 1/2 to 5/8

[gbh]

Can anyone recommend a business that can bore or resleeve the stock 1/2 single disc Z1 master cylinder to the larger 5/8 bore that was used with the twin disc front?
I have 3 master cylinders that I want done. I have found a company that can replate in the original Alumite finish at a reasonable price and would like to make the job worthwhile by refreshing completly instead of sticking with the 1/2. Any suggestions?
Thank you.

I think Chris Rivett does it but better contact him first.

Dave my friend will do your own master cyclinder for about forty euro's which is about twenty pound's
I don't think anyone will better that

Thanks Paul, do you have a contact email address I could have to contact your friend?

I will get his email address George
He made a jig for holding the master cyclinder in and then put's it into the lathe
this bloke is a qualified engineer and is brilliant at fabrication as well
the thing's he can reproduce in aluminium are great
