Coolant question

[parmalee]

Hey guys, I have a 2014 zx6r with I believe might have an issue. I noticed after a ride when I ride back from my Apknite company to my home and park the bike I notice my reservoir bottle is completely empty (I filled it up only a few days ago at the full line).

Now here is the weird thing, when the bike gets very cold and I check back on it in an hour or two I notice the reservoir is full again to where I originally topped it off.

I have no cooling problems or anything, is this normal operating procedure? My radiator is topped off as well, so I'm not sure where the bike took all the coolant from the reservoir and then spat it back out into the bottle.
