Hey everyone I'm a bit stuck as to know why water came out my overflow pipe yesterday after a hot days ride. The bike was hot when I pulled up and the fan kicked in, this was fine up until water came from the overflow and formed a small puddle under my bike, this is the second time thus has happened in a short while. Does anybody know why this happens and if I need to do anything to stop it happening again? Thanks in advance for your comments, ride safe.

Funny you say that, I did switch it off hot but fan kicked in, both times it's happened I've switched off hot!

The fan can run all it wants, as long as the motor is shut off, the water won't circulate. The water in the jacket gets super heated and boils off. The pressurized system keeps the water from boiling at it's normal temperature, once you surpass the that boiling point, you get coolant out the puke tube. You can purchase a race cap if it really bothers you, or wait till the fans do their jobs and bring the temp down.
