During my recent ride to the BSAOC camp in Cheshire. I thought I could hear a new sound from the engine. I have a tight fitting skidlid and also I was wearing earphone buds to hear my SatNav directions. Anyway, I've been cleaning the bike today. I had not run it since the weekend. When I started it to walk it back into the shed I could deffo hear a new rattle. The sound was mostly on over-run and sounded light, like a small chain. So, I took off the timing cover and adjusted the dynamo chain. Started again; same sound. Took off the sump plate to find this!!
The bits are non-ferrous. Slightly curved bronzy appearance. There was no obvious debris at the bottom of the timing side outer case so I hope they are not from the timing side main bearing. Are they from the camshaft bush? I just know someone here can tell me where they have come from. Obviously, I've now got to take the engine down. I have a new camshaft to put in so here is my chance!
