SOUNDS LIKE THE ENGINE IS GONE. VIBRATION ISSUES USUALLY POINT TO THE LOWER-END CRANKSHAFT,ROD,ETC. PINGING IS CAUSED BY THE ENGINE NOT RECEIVING ENOUGH FUEL/2-STROKE OIL BC 2-STROKE ENGINES RECEIVE THEIR ENGINE LUBRICATION FROM THE MIXTURE OF GAS & OIL. THIS LEAN (NOT ENOUGH) CONDITION CAUSES PREMATURE ENGINE WEAR AND EVENTUALLY CATOSTROPHIC ENGINE FAILURE. STOP OPERATING THE BIKE B4 IT RUINS THE CASES OR WORSE;BLOWS A CHUNK OF ROD OUT OF THE INTAKE TRACT AND INTO UR EYES ETC. PEACE & TREAD SOFT.
