When I lost one I shook the bike...and shook the bike...and shook the bike...nothing! After searching with a flashlight, I finally decided to remove all the fairing (from the bottom up, cuz I figured it would be like T Cro said...laying in the belly pan)...and found NOTHING! I was pretty hot by this time, and, for some reason decided to start the bike...as soon as I started the bike...that well-nut came bouncing down onto the garage floor...go figure! My mechanic friends tell me they just go get another one...
