After fitting my new Delkevic headers and getting the old girl running, I found the fi light was on constantly. I didn't fit the O2 sensors so I assumed this was the problem. I terminated the sensors at the connecters behind the fairing, initially I used only two 330 ohm 1/4watt resistors, one per connector in the upper terminals however, this didn't work. After referring to the circuit diagrams I noticed that the sensors have in built terminating resistors built into them between the white wires. So with this new knowledge I put two resistors into each connector and off goes the light. No O2 eliminating connectors to be purchased, 4 x 330ohm 1/4 watt resistors do the job at a fraction of the price. Next job is my own tail tidy (fender eliminator) using existing parts and as inexpensive as I possible. No more than £30 ($50 approx.) including new number plate.
