If the FI light came on and stayed on at any time, that fault will be stored in the ECU.
You won't be able to find out without pluging your bike into a diagnostic computer.
What I would do for now, if the light has gone out, use the bike as normal and see if the problem persists.
Don't worry too much about it, It could have just been an anomaly of some kind, it does happen, just keep an eye on it ..
