■Φ57 SCUT Cylinder/Piston Bore diameter 57mm Φ57 SCUT cylinder has the same design in appearance as the original cylinder of the Cub series engine, but without the skirt part. By adopting this cylinder, it is possible to install the cylinder without any modification of the crankcase even for Φ57 cylinder. The cylinder is equipped with a temperature sensor as a standard feature, and the cylinder temperature can be measured by using SP Takegawa's built-in thermometer or by purchasing a thermometer. Φ57 SCUT cylinder: M5 temperature sensor Scat cylinder is equipped with an oil jet mechanism (patent pending) The oil jet cylinder is a cylinder that allows oil to be injected into the cylinder and pistons without replacing the crankcase, disassembling the crankcase, machining the oil jet holes, or adding parts for oil jetting. The oil injection holes are located directly on the inner surface of the cylinder, allowing for uninterrupted oil injection through the piston skirt and the inner wall of the piston during engine start-up for efficient lubrication and cooling. Scat pistons are pistons with a shortened skirt. By using this piston, there will be no interference with the crankcase at bottom dead center. The piston skirt is coated with molybdenum for better initial acclimation.
■MIKUNI VM22 Carburetor Kit The kit comes with a manifold that allows smooth intake from the carburetor to the combustion chamber without resistance, fuel cock, throttle cable, and air filter.
