I want to ride my bike a couple of days ago and neither if the headlights would work. I checked the fuse and it was good so it has to be either the switch or the relay. I decided to throw a relay at it bacause it is relatively easy to get to and they go bad more often. Honda only uses 2 different relays on the F4i the headlight uses a 20a relay. That looks like this...

It is located in between the headlights in the front fairing. The hardest part is getting the fairing off and on the only tool you need is a allen (hex key) wrench...
