Bonneville America Forums Forums Technical Forums General Tech Help with cylinder block please

Hi Everyone- anybody got a super nice cylinder block for 07 Speedmaster they wanna sell? I am looking for one I can just put on with just a light honing. Mine need replaced. Thanks

Are you looking just for the barrels? If your planning on honing it, you should get new rings to go with it.

Big Bore kit?

The jugs on our bikes are coated aluminum, I am not sure you can just hone them. I think you would need to coat them again. I don't know much about the nicosil coating, how thick, honeability, etc..

I’ll mic them to see if it in spec then if not send it out- when in spec I have just deglazed them with nikasil honing tool I have. Done several as was trained to do it

Have new everything
