Until marks on magneto flywheel and magneto “1” cover are aligned. Mark on magneto flywheel “1” Notch on magneto cover Location of crankshaft position sensor At TDC ignition, the printed marks on the camshaft timing gear have to be parallel to cylinder head base as per following illustration. TYPICAL Printed marks on camshaft timing gear Cylinder head base Insert the feeler gauge between the valve stem end and adjusting screw on the rocker arm to check the clearance. If the valve clearance is out of specification, adjust valves as follows. Valve clearance Intake 0.05 to 0.09mm Exhaust 0.10 to 0.15mm Use mean valve of exhaust/intake to ensure a proper valve adjustment. Hold the adjustment screw at the proper position and torque the locking nut. Repeat the procedure for each valve. Adjustment screw Adjustment nut Feeler gauge Valve clearance adjuster locknut:12N.m Install the valve cover of both cylinders, spark plug cable and spark plug of both cylinders, the plug screw and of magneto cover and the crankshaft position sensor.
