Well as some of you know. I have had some cooling issues with my low mileage 79 CX. After finally getting it sorted out I had cooling problems and received a lot of help from everyone here. So here is what I have done and the results. I took the thermostat housing out and took it apart. Even though the bike has 3100 miles it sat for 25 years. Inside was really corroded and the water inlet for the heads was crystalized. After sourcing a new thermostat, I put the housing back together with new o-rings. I flushed the radiator while the bike was running for ten minutes. I filled the radiator up with water and white vinegar 50/50. I then rode the bike to dinner with my wife and the bike never quite got to the red. We rode for about an hour after dinner and it only hit the red when we were riding really slow for quite a while. Out on the open road, it stays away from the red but is still a bit hotter than I would like. I am going to drain the water and vinegar tomorrow and fill it with Engine Ice and Water Wetter. I hope this will solve my cooling problems. Now, what say you on this?
