Following the ideas from expert guys on this list, it is not probably a serious problem since your bike runs fine. You have to let us know whether the red light blinks or stays lit.
As per your initial comment, it seems to me that the FI red light stays lit even though your bike operates well. If so, there should be a faulty on ECM caused probably for reasons explained by LadRodent (hiccup), or even some connector/wire needs to be checked. I suggest, disconnect your battery’s bike beginning by negative cable, then disconnect the positive, hold 5 minutes at least, then connect positive and the negative and check. If light keep on, check some wire and connector from PGM-FI, you might find water or corrosive fouling.
