KSC gave me a hand to complete the " Inspection of Valve Tappets " as required by Rotax " Purging of Lubrication System." All rocker arms were hard as per the inspection requirements. I re-installed the spark plugs and torqued them to 20 Nm and re-installed the valve covers and torqued them to 10Nm. The " Purging of Lubrication System " is now complete. ( No room for photo of cylinder # 3.)
