Once you have the key housing out, you will need to remove the lock washer/thin nut off of the threaded portion of the housing unit. It is low torque, remove it then the rest of the housing. There are 2 screws on each side of the black switch housing that you will have to remove the you should be able to get to the two lower handle bar pinch bolts.
Had to do mine, purchased bike from dealer which was 3 1/2 hrs away from home. Hit a bump on the way home on the day of purchase, handle bars almost fell to the tank!!!... was almost home and was not about to turn around to go back to the dealer, so did it my self after calling the service dept for help.
