When you consider the amount of thread lock that Kawi puts on most of the bolts, it's not suprising that the ones they DON'T lock fall out.
A true cynic would look at the price at the dealer of bolts and wonder.
That said, the only one that fell off mine was the ornamental one in the center of the top fork bracket and my dealer replaced it free, even though it listed for 20$ +/-.
