small chance there is an air lock in the system. when you fill up the coolant have the bike running to see if there is flow through the radiators. that will also show if the water pump is workling

(think this will only work if the thermostat is off .. or you use boiling coolant which i think would be a bad thing to try lol)

Thanks, I will try both of those things.

I didn't want to stop riding, so I removed the thermostat from the housing and flipped the housing over, thinking the hoses might hold with "free flow" and a different orientation. Now the top hose popped off.

At one point I did put a rag over the radiator cap and remove it while "hot" (or so I thought) to see if I was overheating. No boil over, no pressure, no steam - it is a somewhat of a mystery to me. There must be pressure if the hose is coming off - but then it would be seen at the cap. Maybe I didn't run it/heat it up as long as I thought.

I'm running Engine Ice btw, maybe it doesn't boil over like ordinary anti-freeze.

Thanks for the help, I'll let you know if it looks like o-ring or air lock!
