I had an unfortunate tipover in the garage and bent the fairing stay so badly I think it might be toast. Does anyone know the part number for the 3EN1 fairing stay? I don't have a parts manual for it. Thanks!

Not off the top of my head assuming you mean the main nosecone stay. However, it's the same part as the FZ400/FZ600 as the 1WG shared parts with it's predecessor. It may even be the same as the FZR600 3HE, successor to the FZ600, but I'm not sure.
