[QUOTE="Rcannon, post: 674691, member: 26263"] BigRed, I am thinking of another bike we just rebuilt. The CR 80 had been running Yamalube R as well. The piston was allowed to stay in the bike for over a year of hard riding. Finally the intake skirt let go. Despite all the hours, there is no burn pattern on this piston. The powervalve on my YZ was also spotless. I know this is just two examples, but I would have a hard time argueing with what you say. [/QUOTE]
