It happened to me this morning, down on the stand pivot undo the small bolt holding the black plastic switch that the sensor lead connects too. On the back of it you will see a small pin that fits into a hole on the arm that rotates to switch off and on. The problem is the bolt behind it that holds the arm onto the bracket. It came loose, just did 3 turns to tighten and the pin was then able to sit back into the hole. All done with a small shifting spanner.couple days after first service, side stand error, bike don't run !!!! the error is displayed on the screen, even when the side stand is up!!!! is anybody having same problem???
