Honda Blackbird.?
Answers:
It's FI, which is the Fuel injection/ignition electronics. If yours is lit when the bikes running it's not good. You need a dealer quick!.
Is it definitely f1? all i could think of is FI fuel injection if it has it.
If the light is lit when the bike is running, one of the sensors in the fuel circuit are detecting a problem. It's the same as the "check enging" light on a car.
