IMHO, steel liners won't work with the OEM-style piston rings available on the market. Oil rings have steel rails and most likely will destroy the steel sleeves and the rest of the motor with them. Not something I want to undertake, lol
The OEM sleeve material for this application is gray iron...
Thanks for the responses.
Steel is probably out of the question due to cost and lack of desired longevity.
This is custom application, no OEM replacements available that I could think of.
What would be a recommended material for machining a cylinder sleeve?
G3000 spun-cast iron seem to be quite popular, but I'd love to hear an expert opinion on this.
Application is an air-cooled motorcycle engine; aluminum finned shell, pressed-in flanged sleeve.
The sleeves have 3-1/2" bore...
