Re: Red Light On....)07 Gsxr 600????
I can't really tell you the answer to that. A: I'm not that good. B: The FI code could have been anything. So if you didn't get the code when it was flashing, then you'll never know which one of a number of systems to inspect to make sure it was nothing.
That said, my unprofessional opinion says as long as there are no symptoms: don't worry about it. Stay familiar with how to jumper the bike and keep those tools with you on the bike so you can pull the FI code ASAP if it happens again. (I recommend buying the switch for this, as after a while you may forget which cables to jumper when you're pulled over in a parking lot... fried ECUs are pricey.)
If you just turned off the bike to make the FI light go away, you're probably fine. What were you doing when the light went on? (Certain kinds of things like, ahem, hard acceleration can cause a C37 code. I learned all about that one. Perhaps you can duplicate the conditions?)
