flyguyeddy... Sorry, but I don't have the 25cc cylinders and pistons. I bought just the cranks a while back from someone here in the forum. (It's been a while and now I can't remember who sold them to me.)

Ralphbf... Would you happen to have links or other sources you can share for those reed valve assemblies? Most everywhere I search says "no longer available."

Thanks,
