I think someone on this board already knows the answer to my problem, so I make it quick. When I am coming to a stop, and my rpms drop between 1500 and 1000; I can hear the rattle noise (almost as if its right underneath the valve cover) like a pebble bouncing around in a tin cup. It never make a noise below 1000rpms, nor does it make a noise during acceleration. I have not exp. any loss of performance of any sort, but I am afraid this could led to BIGGER problems. And by the way, I have the Honda CARE 100K waranty on the Lude...Do ya'll think they would warrant this?
