Can anyone ID the metal fibers on this magnet? I emptied out the oil tank to get it ready for paint, well there was oil left in it so I decided to run a magnet in it to see if it would pick up anything. Well it did and this was just the oil left in the tank, I haven't even checked the other oil I drained out the bike. I'm already planning on tearing this motor down but I am still working on my frame rebuild before I touch the motor, just want to see if we can ID it.
