Coming home from 4 days of riding in the Sierras in California. On my way home yesterday in the hot lower Sierras my bike was over heating with an occasional FI code showing. I started to hear a moderate clacking sound coming from the engine area. Pulled over with fellow riders. Continued riding after 15 minutes rest and sound got louder. So I stopped and started a couple of more times. Rode in neutral on the downhills and motor cooled down and less noise. Anyway finally it got louder and it started to over heat I immediately pulled over into some shade. My overflow reservoir was boiling and finally the water/anti freeze released out the overflow tube. I took it in to a shop today. I am about 330 miles from home. They will give me an idea of what needs to be repaired. What do you think it is. It sounds serious to me. Luckily fellow member Keith put me up at his home and picked up a trailer at UHaul to move it to the local shop. Connie riders are the best!
