There is not a better sound than a three-cylinder two-stroke engine and VintCo has all new crankshafts completely assembled for your vintage 1972-1975 Kawasaki H2-750 that will get you back on the asphalt after your rebuild. These crankshafts are assembled with Heavy Duty Forged Steel connecting rods with the wrist pin bearings included. The connecting rods with a more modern design and an updated wrist pin bearing. The connecting rod has a large ventilation slot for extra cooling and lubrication. The use of special Polyetheretherketone (PEEK) coating on the lower bearing allows for superior performance. The updated lower bearing cage has additional needle rollers for added durability. The Crankshafts come with the correct multi-lip rubber oil seals and NTN/TPI main bearings. We pinned each crankshaft to help eliminate torque slip. The crankshaft does not come with the troublesome oil slinger. This Crankshaft has a 18mm Wrist Pin that is considered a High Performance version, as the stock crank has a 16mm wrist pin. Custom VintCo pistons are required to run this crankshaft. If you want the standard 16mm wrist pin version that part number is CR2009.
