2008 Triple petrol overflow

Hi all,

I have just bought a Speed Triple, and have noticed that its leaking petrol through one of the overflow pipes... I'm not sure if there is a pipe from the injectors and one from the tank? but i noticed it 2 days ago when there was no where near a full tank and again today. I filled up this morning but have rode a good 30 miles since and there are still some droplets coming out... Anyone have any ideas why its doing it?

Thanks,
