As Nigel discovered, a common problem with superbikes is that after running fine and then shut off, it won't start again, say after a refueling stop. Sometimes if you wait a few minutes it will restart normally.
The culprit is the two-wire plastic connector plug located behind the starter relay (the round gold component near the battery.) The connector often makes a poor connection from distortion or corrosion. Usually jiggling or unplugging and plugging the connector will get you going again.
