THE ENGINE CASE HAS 2 SEVERE CRACKED IN THE PLACE WHERE THE FRAME MOUNTS TO THE ENGINE. THIS IS COMMON WITH THE S2R AND ST3 BECAUSE OF A DESIGN FLAW IN FRAME DESIGN ADDING INCREASED PRESSURE TO THAT PART OF THE ENGINE CASE. *TR
FUEL TANK HAS SHIFTED AND EXPANDED TO THE POINT WHERE IT IS AFFECTING THE IGNITION SWITCH AND PRESSURING THE FASTENERS THAT HOLD THE TANK DOWN. *TR
GAS TANK HAS EXPANDED TO SUCH A POINT THAT THE LATCH SECURING THE TANK TO THE BODY CAN NO LONGER FUNCTION. THE GAS TANK COULD BECOME LOOSE WHILE THE VEHICLE IS IN MOTION CAUSING AN ACCIDENT. *TR
