Axial float plate

An internal combustion engine provided with a crankcase having a back wall and a crankshaft, the crankcase including twin cylinders arranged in a V-shape in a plane normal to the axis of the crankcase, each of the cylinders provided with inlet and outlet valves and a cam chest having a cover separated from the crankcase by a divider wall, comprising:

• a first camshaft provided between the back wall and the cam chest cover actuating the inlet valve and the outlet valve of one of the cylinders, said first camshaft provided with a first flange having a first groove;
• a second camshaft provided between the back wall and the cam chest cover actuating the inlet valve and the outlet valve of the second cylinder, said second camshaft provided with a second flange having a second groove;
• a gear train housed in the cam chest including a drive gear provided on the crankshaft for driving said first and second camshafts, said gear train additionally including a primary gear and first and second secondary gears, said primary gear and said first secondary gear provided on said first camshaft and said second secondary gear provided on said second camshaft, said drive gear engaging said primary gear, said primary gear engaging said first secondary gear engaging said second secondary gear;
• an axial float setting plate having a pair of notches secured to a divider wall in the cam chest, one of said notches nesting in said first groove of said first camshaft and said second notch nesting in said second groove of said second camshaft, said axial float setting plate controlling the longitudinal movement of said first and second camshafts constantly maintaining a first gap between said first and second flanges and said axial float setting plate.
