That is part of why I put an O2 Sensor and Gauge on mine. Still working out the idle mixture. Will move on after I get this close and let everyone know what I ended up with.

I'm very interested in your 02/Lambda sensor work. Will follow with interest

I see a couple of you are using the Innovate wide band O² sensor and I'm not sure if you've followed this instruction on free air calibrating the O² sensor so here's a link. Pretty straight forward.

Once you've got your O2 sensor is calibrated (?) I'll make a suggestion regarding the 6 idle (fuel-air) needles.

You really do need to remove the sensor from the exhaust for this. Be sure you install it in such a way that this is not a PITA to do. We end up re-calibrating the sensors in the race car regularly (multiple times a year) for various reasons. On the bike I have it mounted so I can do this and only have to cut a zip-tie or two.

I hope I didn't screw anything up, as I was being careful and connected the right wires. It's an expensive gauge....
I used Colortune for checking the spark.

We have used the Innovate meters in lots of cars. Have never messed one up. I'm confident we've not got the wiring right first time on more than one occasion. Other than an occasional O2 sensor failure (which is obvious) and needing regular calibration, we have not had a failure. On our ECU controlled cars, we can turn off auto-correction when the O2 fails until we get a replacement in. BTW, these are Bosch sensors - you don't have to order from Innovate for replacements.

But, they are sensitive to voltage. On the bike, the gauge reports an error when the engine is cranking - the voltage is too low. I've even connected it direct to the battery and it still does this. But it's not really an issue, as soon as the engine fires the gauge is happy.

Just crossed my mind. Does the sensor being screwed to the welded bung act as ground? Having mine on a stick would be a problem right there and perhaps also an answer...
I'll need to check it. It doesn't come on at all when connected to the battery (through the plug - I use the same plug for checking voltage and charger if needed). Just a dead gauge like if there is no power.

Mine is AEM, and says it doesn't need calibration.

I insert the rod into the heat protective sheet to put it inside the exhaust.
