Hi everyone. Ive just purchased new Yamaha oem rings and valve stem seals to install on my bike and one of the compression rings has a white paint marker on the outer edge. Does anyone know what this is or what it indicates?

The rings have a manufactures mark to indicate which end goes up. Unless you have identified another mark as the up mark, this may be what it is for. Since the gap in the rings is what is used as a reference for the position of the rings, I wouldn't think it has anything to do with that. So as long as you have the correct side up, and the gap in the correct position, I would think you would be good to go.
