I too recently purchased a new 07' and I am following Motoman's break-in procedure. The more I thought about it the more it made sense. At 25 miles I performed an oil change but not a filter change (didn't have the filter tool) and I can tell you that there was definitely a metallic sheen to the oil. It just makes sense that seating the rings into a honed bore (even though it is a fine hone) will initially produce some metallic particles, plus materials that were not completely cleaned from newly manufactured parts during engine assembly. If you wait until 400 miles or more, my guess is that the oil darkens enough that you cannot see these near microscopic metal particles in the oil. But with clean oil it was very obvious and I'm glad I did it. I just used straight valvoline 10w-40 as suggested to help with the break-in process as opposed to something "slicker" that could actually hurt the process. After 1,500 miles I'll switch to a high quality motorcycle oil.
