My guess is that the FI light is because the speed signal is faulty. The connector for the speed sensor is on the right side near the lower vent. There are 3 wires, One is ground, one is power (+12 volts from tail light circuit if I remember correctly), the other is output.
The output is 5 volts and will turn on and off every few inches of rear tire travel.

If you feed a 5 volt square wave at about 1 kHz it will put the speedo at about 100Km/h.
