I had the recall service performed last year where they replace the original radiator-to-pump hoses with longer ones to prevent them from backing off. Then, a couple days ago, that's exactly what happened. No crash or other provocation, just riding the bike to work & back. The upper hose worked it's way forward off the water pump spigot just through the course of normal riding. My suspicion is that the water pump housing may have a slightly under-size spigot, and/or an insufficiently aggressive barb. The spring steel hose clamps work just fine in most applications, and there's no reason to blame the hose. There's no stress on that little length of hose except the pressure cycles generated by heating & cooling the system. The hose can't even move very far, both my hoses were jammed forward against the back of the radiator. So, I suspect the hose is being "inflated" by the hot pressurized coolant, and working it's way off the under-sized water pump spigot due to internal pressure. I will measure the spigot when I have time to disassemble the system. SO: Heads up. Even if you've had "The Fix", you should keep an eye on these hoses.
