Hi Mike...I'm assuming it doesn't feel or sound as smooth as it did before you cleaned it? It's possable you dis-lodged some crud, and it got into the bearing. FWIW, I have a brand new Speed .50, and the bearings feel and sound a little rough and noisy. I haven't run it yet, but I'm hoping they'll wear-in a little and smoothen out some. We'll see...(there's no symbol for crossed fingers on my keyboard )
