If you could also expound a bit more on the headlamp removal thing too...
On my old PCX, I had to take body panels off to get to the headlights, before I discovered that they could be reached by going up underneath from the wheel-well area. Problem with that was not enough grip was possible with the hand position necessary to reach, so I couldn't generate any turning force. That is, until I made a tool to fit over the bottom of the headlamp. Cut a circle out of some 1/2" thick hard plastic, and demeled out the shape of the bottom of the bulb. Worked like a charm. If I can do this to the X400i, it will simplify things when it comes to bulb upgrade.
