I was talking to an old digger the other day when the subject of rings came up.
He said he fits some sort of Mitsubishi rings to his Vincents and reckons they are far superior to the originals. A few years ago I helped replace the rings in a Hyundai Excel and was suprised at the detail the designers went to. The top compression ring was chamfered, the second was tapered and the oil ring was in three pieces and they all had a correct side up. The NOS rings that came with my pistons are the same ones we fiddled with forty years ago. While I intend to use these rings, I'd be interested to hear if anyone has information or experience with the use of modern rings in our motors. The excel motor was hardly state of the art so there must be some benefits.
