Been a persistent problem with the Fuel Injection on the Hayabusa, but unknown as to what was causing the FI light to come on randomly. Ntm my first FI bike so a first for me.
FI light comes on after long day of riding, and motor experiences momentary throttle surges. Tried turning the bike off (while riding) and restarting. This turned the FI light off for awhile, and it'd magically run fine. Then it'd start up again. Stumped. Finally brought the bike to Good Times Kawasaki in Sacramento and dumb problem had simple solution.
Throttle Position Sensor (TPS) was not set properly, and so mechanic reset it and bike is supposed to run fine now. Time will tell if this fixed the problem.
