Engine with an excellent stroke with its bore / stroke of 47 X 44.9mm (not far from the square), the long stroke crankshaft brings a net gain in torque especially on the AV7 engine without valves, where the piston plays the roll of opening / closing admission. This engine is built to take high power and speeds of 10,000 / 11,700 RPM. It comes preset with a sharp lowering of the carburettor jets PHBG, necessary on engines without reeds.
