Honda CBR400RR NC23 (Tri Arm J-K 88-89) Oil Pump Assembly

Honda CBR400RR NC23 Tri-Arm (88-89) oil pump assembly including oil pump, strainer, drive chain, drive sprocket and oil pressure relief valve – all appearing to be in good usable condition.
Removed from engine number starting NC23E-109… from which all engine parts appear to be okay, presumably the CBR400RR NC23 donor having been broken for parts due to accident damage.
