I've never had a problem before, but just recently during a very hot spell, my Zuma 50F has started to show the overheating light. The weather has since cooled down, but it still overheats after semi-long rides. I've tried changing the coolant to no avail, and I've also tried using the air bleeder screw (maybe I'm doing it wrong?).

The radiator does seem to take a really long time to actually get hot, but do the water pumps really go out on these? Could it be the temp sensor? I don't think the sensor has failed completely, because it does go away after I let it cool down for a while. Then when I ride it some more it'll come back on. I'm kind of stumped.
