   * The washer that separates the feed from the scavenge gerotors on 2007 style Buell oil pumps can freely rotate and wear against the inside bore of the pump. The pump bore is not grooved but can be worn in from the washer spinning during use. It does slowly introduce aluminum into the oil supply and return but very slowly and the oil filter should take care of any problematic debris. Also, the piston jets do not have a check valve. They are free flowing. ​   * The washer that separates the feed from the scavenge gerotors on 2007 style Buell oil pumps can freely rotate and wear against the inside bore of the pump.

 +Note: Since the XL Oil Pump (26204-91A (new style)) is the same oil pump as the 2007 later Buell Oil Pump (26357-02B),​ the same issues listed here should be expected.
