I am in the process or rebuilding my motor, and when i looked up a part number for the valve lifters (bucket), it only lists lifters that have the color marker for black, blue, or yellow. The color on the bottom of my lifters is red. One of my lifters was damaged from the cam circlip not being installed in the right spot. (the reason for the rebuild) It is a Canadian bike and I don't know if this really matters or not. I was using a fiche from a buisness in Grand Rapids Michigan (Shawmutt Hill Sales and Service).
