Hi all Would be grateful for the advice of more experienced members! With the oil pan still removed from my GSXR250, I noticed something caught by the mesh of the oil strainer. So I removed the strainer, shook it about, and this is what came out... Other than the above, the oil pan was pretty clean with no other debris to report. At first I thought these brown chunks were oil that solidified within the oil strainer, because some of the edges seem to have a rounded form to them. But after a bit or research, perhaps they are pieces of plastic timing chain guide? Would be grateful to get your views on: 1. What you think the pieces are? 2. What you would do next?
