It is the 3rd time for me that this happens to me as well. CBR500R 2016 model.
First time when I bought the bike (second hand used at 4500kms). It was empty. Brought it to the dealership (as it also had the water pump leak problem). They filled it up
Within the following 1000kms, empty again. Dealership claimed it must have been due to the water pump swap. They filled it up again.
In less than 500kms, it is now empty once again. Bike has now 6000kms. Haven't brought it back to the dealership just yet, but I'm pretty fed up with it.
I've noticed that when the bike is hot (is running or has been running shortly before), the jug seems to have at least a bit of coolant. However, when the bike is completely cold (checking in the morning for instance), the jug is 100% empty.
On an additional note regarding this bike's problems: This isn't directly related, but I've also noticed that when I turn the bike off I hear odd mild noises coming from the fuel tank. Sound is intermitent (every 10 seconds it sounds for 2 seconds or so) and the noise is just like that subtle sound of a far pipe of a neighbor in the middle of the night running water inside. When I open the fuel tank it seems to have some suction on it.
