    Correct me if I'm wrong, but Honda CR's did not power valve until 1992. I have a 92 CR 250 and the 91's are not power valved. Not sure about other Japanese manufacturers, but Honda was pretty much ahead of the pack back then. Possibly Kawasaki powervalved in the late 80's since the tecate had it, but for sure not Yami and Suzi
