Fuel leaking into exhausts when parked up

So just bought a TRX 850. Love the bike but don´t really know my way around it yet. Anyway I filled the tank a few days ago and drove home then parked the bike in the garage. Three days later I went to get the bike out and noticed a puddle of petrol on the floor where the pipes join with the exhaust. Stripped the cans and the pipes were full of petrol. They were still dripping fuel. The fuel cock was at the 6 oclock position which I believe is the main and when I turned it to 12 oclock or reserve it seemed to stop. What would cause this, any advice?
