What was found
WHILE PERFORMING A COMPRESSION CHECK ON THE CYLINDER FOR THE 100 HOUR INSPECTION, HAPPENED TO LOOK AT THE CYLINDER BOLTS AND NOTICED ONE OF THE NUTS WAS MISSING ON THE TOP FORWARD THRU BOLT ON THE NR 2 CYLINDER. LOOKED AROUND ON THE BAFFLING AND FOUND THE OTHER PIECE OF THE BOLT WITH THE NUT STILL ATTACHED. WENT OVER TO THE NR 3 CYLINDER TO LOOK AND FOUND THAT THE NUT WAS MISSING ON THE THRU BOLT AFTER LOOKING AROUND THE AREA, FOUND THE NUT ON THE CYLINDER BAFFLE. AFTER LOOKING AT THE NUT AND THE THRU BOLT, IT APPEARS THAT THE THRU BOLT WAS OVERTORQUED AT THE FACTORY. HAD TO REPLACE BOTH UPPER AND LOWER THRU BOLTS.
