I bought a Suzuki Every Joy Pop. During start up of the engine there is a grating noise. After the engine is warmed up. The sound disappears, Can anyone tell me what is the problem. Any answer is much appreciated. Thank You.
Have you changed your oil lately? Could be piston ring and cylinder making the scratching noise. According from a mechanic I talked to, you should not step on the gas pedal too much when you first start your engine in the morning especially when the engine has not been running for a while. Why? Before starting, almost all of the oil is in the oil pan, there are little oil clinging in you piston ring and cylinder. After starting, the oil pump starts pumping oil through you engine to lubricate things, but its not that instant.
