Questionhow do you intall an air fuel meter on a 03 gsxr 750 when their is no oxygen sensor.
AnswerHi Travis,
To install a A/F gauge, you'll have to follow manufacturer's instructions.
You may have to buy and install a compatible oxy sensor.
If you're not sure about what to do, have a pro tech do this work for you.
