I'm with Pete on this. Seems like a lot of work for fear of something that may go wrong, but likely won't. The immobiliser system works just fine, and you'll need to overcome the signal sent to the ECU from the instruments that prevents engine start. The tip-over engine cut-out is a safety feature that I've had the unpleasant experience of utilising, but am thankful for.
While I'm all for people modifying there bikes, I feel this project is one I can't support.
