Hello together, I bought a new 04 Fatboy. From the beginning I had a bad feeling about the engine. When you turn the engine into a smaller gear you feel a vibrating or clapping from the engine block as if something loose was lying in the block. You notice it amplified when you turn the engine up and then take the gas away and reduce the speed by compression. The Harley dealer said that this was completely normal. wave of the TwinCam 88 B. However, I have to remember that this is really so noticeable. Did someone have similar experiences with a TwinCam 88 B or do I really have to make a hat? Greeting Berno
