850 Piston Rings

Anyone know of a source and if they are even made of .010 over piston ring set for my 850? I am being told by 2 suppliers that you can only get them starting at .020 over. Any ideas? Thanks.

Hi Denny850,

FWIW ... I have seen a few go by on eBay ... maybe once every few months or so.

I found two sets of .010 over 850 pistion ring sets. I bought one set from Domiracer (Assory Mart) in Cincinnati and Phil Radford had a set at Fair Spares America. This is after I was told by Norvil in England that they do not exist and have not been made in years. You never know until you try!
