Is the exhaust hitting somewhere? The sound of the engine sounds normal but I heard a sound next to it as if a sheet was hitting left and right .. my speakers are small so I can't get clear sound ..

The sound is not normal. There is a click sound abnormally. An iron looks like a thin sheet. I was like the injector sound.
