You said it speeds up? Oh dear. That's not the fuel pump.
A friend of mine had that on his bike, ignored. Next thing he knew, the bike blew up. The ignition sends a high current pulse of voltage through the full system as a self diagnostic. The ticking you heard is a danger sign.
What isn't publicised (it's pretty rare) is that all fuel sensors have a nasty fault which means they can fail castastrophically. The ticking is the first symptom is the ticking. The fuel pump and fuel sensor are on similar circuits, and the pump runs BACKWARDS for a tad. This can mess up the fuel sensor. If you're riding, and it seems like the fuel indicator is jumping around abnormally, bail out! It means the sensor is about to fail completely, and fall out of the tank, dumping petrol onto the cylinder block, and the airbox. And if the adiabatic atmospheric sensor is faulty - boom.
You have been warned.
