losing coolant but not leaking

Hello everyone. I am new to this forum and new to Husabergs and 4 strokes. I have always owned 2 strokes but I just bought a 2008 fe450e with 13 hours on it. I have no coolant leaking out of the engine or radiator but everytime I open the radiator cap the fluid is down below the fins. I just changed the oil and didn't notice any coolant in it. (What would coolant in the oil look like?) The bike does not smoke at all and I did check for bubbles in the radiator while the engine was running (nothing there). Any suggestions would be appreciated.
 
oil gets milky when it has water, past experience with a blown water pump seal on a 300 EXC. If there's no water in oil, then you might be leaking water into the cylinder and blowing it out the exhause? Head gasket? Pull plug.
 
the bikes are known for pushing coolant out when you are riding in tight slow tracks, you need to put a over flow bottle and you wont lose any coolant.
there is a hose off the top of radiator behind the radiator cap that is where the coolant comes out when it is hot


as long as you dont have milky oil then this will be your problem
 
A guy told me his leaked out the headgasket near the headers and he didn't see it because the water evaporated.

could be true, everything else he told me wasn't ! :evil:
