Don't tell them you wrecked it, just say you did some race mods. And the FI means Fuel Injection, it is a sensor that blinks when you tip your bike over. It happened to me the first time I lowsided b/c some girl with her permit was learning in a ****ing extended Tahoe and pulled out in front of me in a turn. That's besides the point. Back on track, if that FI light stays on after disconnecting your battery terminals and restarting the bike then you need to take it to a dealer. There may be a sensor problem or that wreck could have jacked up your FI worse then you know. I would disconnect the Tachometer and the battery terminals. Check for broken wires, reconnect them. Then insert your key. Flip on the starter switch and make sure the tachometer goes up and comes back down to zero. Put the bike in neutral and start it, this should reset the Tach and the electrical system. If that FI light stays on then you need to see a dealer. Hope this helps bud, just be cool with them and tell them you read the owners manual front and back. Also tell them this is your second Gix and you have experience with them or they will try to rob you. Rock on.
