Hi
I installed my old o2 sensor (from my e assisted carb) and got readings between 0.46 to 0.50 ac volts at idle (my personal multimeter is not a cheap one), and under acceleration in 2nd or 3rd gears got 0.50 at 3000 rpm to 0.56 at 5000 rpm (stock cams and dual mikuni 40 carbs)
Acording to this

I am at the proper jetting for an economy setting (have to admit gas lasts a lot
)
Question is, what is a proper air fuel ratio for a performance engine? A race engine?
I found 13:1 to be a recomended setting

Thanks in advance
