I'd like to have a second cylinder on hand just incase anything happens, and I've got my eye on a '97 RM250 cylinder in great shape, looks about perfect, and all that I've read that is different than the '96 is that the powervalve got revised. This would probably hit the jetting a tad off, nothing major though. But physically am I looking at anything bolting it on, or should I just stick with a '96 cylinder? Pistons are the same I assume also.
