Hey guys, I bought a 2000 yz426 a couple months ago and have only riden it 3 or 4 times, all short trips say 15 to 20 kilometers each. I decided it was time to change the oil. I pulled the oil filter and noticed small filings in the fins. I washed the filter in clean gas and saw that there was quite a bit of material, i dont have a magnet so i dont know if its steel, and i didnt see any brass. Is it normal to have some filings between oil changes, i know when braking in a new engine you will get some material on the first oil change. This is my first 4 stroke so any info would be appreciated.
