OK the problem is either in the ignition switch, unlikely or the plug that connects to it. This plug is located under the fuel tank and forward of the air-box (I fairly sure).
:arrow: Power going into the plug is the Red and blue wire, which turns into a blue wire the other side of the plug, it then goes into the ignition unit and back out on the red wire when the ignition is switched on. Check the plug pins for corrosion.
:idea: Do they come on when you select park ? if yes, then its the red blue wires, if not then its the red wires. :)
For Tech Questions Bike Model letters are more useful than saying the year, for uk owners anyway, as registration year is not always year of manufacturer model.
