I need to pop the tank off so I can run the wires from heated grips to multi plug under the seat, how hard is it to get off? I'm presuming that when I remove the fuel pipes from the tank underneath that it's not going to piss all its fuel out, I'm more used to messing about with my 2 strokes with fuel taps, plus I think I'm a bit nervous because the bikes only 4 days old!
