Have you been losing any coolant at all?
Once the bike cools down it should stay around the same level in the expansion tank if the system is all good.
You say you drained and refilled the system, but have you actually cleaned the system using Radflush?
If the waterways are clogged up at all you will end up boiling the coolant then it will dump it out of the expansion tank, which in turn will mean not enough coolant, a hot engine, then the fan coming on.
Putting the bike on the centre stand to check the level of coolant (when cooled down) will immediately give you an answer to the above.
