Almost every member here posts a pic of the magnets/drain plug on their first oil change, and let me tell you, I have seen some pretty nasty ones! But it's the nature of the beast, every brand new motor will show signs of metal shavings, chunks, burrs, fine metal particles, and silicone in the first few oil changes. The reason why a lot of people on here freak out is because it's new to them.
Most new vehicle manufacturers break in their motors before they are ever installed in the vehicle, which is why you never see anything like this in most new cars/bikes. They have already done the break in procedure and have removed all that nastiness with the first couple oil changes at the factory before you get to see it. It just adds to the charm of an RE IMO. But this is also how it was in the days of old. Before the 70's, when you bought a new car, you had to do the same kind of procedure. Take it very easy for the first 500 miles, change the oil in a few hundred miles, then 500, then 1000, then start abusing it.
Modern computerized factories have taken this joy away from the new consumer.
