Wide Band Oxygen Sensor

Of course, it's the exhaust as Jeff & Terrarossa say, Sorry, I wasn't thinking. I have 4 into 4's, so maybe if all carbs are the same settings, I could use an adapter near, just one, of the exhaust tailpipe outlets. What dia/ size is the pitot tube or is it a screw in sensor like on automobiles?
I was hoping I can make an adapter to be temporarily attached to one and move it to another of the exhausts without drilling same.
Approx what is the cost of a LM2?

You'll more likely want to install a bung in each tail pipe to do it right.

Thanks DD, looking at your Amazon link... Possibly decided on.....Innovate Motorsports 3795 DB BLUE Complete Wideband Gauge Kit (2 1/16 52mm) with LC-1, O2 Sensor, Bung and Plug.
If I go for a mount at the extreme end of exhaust, I'm worried about ~
1. length of cable from h'bars to end of exhaust (impedance etc).
2. Tubulence around baffle orifice. Bung adapter would be mounted in this area.
3. Sensor mounting orientation (right angle) to flow.

If you mount the O2 sensor at the end of the exhaust pipe the heater will stay on continuously and run your battery flat (10 amps I think). Best idea is to mount it about 15-20 inches from the exhaust port.

It's a spark plug thread, M18 I think.

Mount it at an angle sufficient to keep water from standing in it.

Good point. At startup, each O2 sensor uses 2A for the heater(Measured on the Innovate system I have). After it comes up to temp, each uses about .7 amps in free air to maintain temp. The more heat you can get from the exhaust, the less electrical power you will need.

I got my complete kit (LC-1, Gauge, cabling & bung) for under $200...
Simpler on a 4-1 exhaust (mid pipe bung)...

Innovative LC-1 & Gauge kit

During my research for the model I chose, came across a AFR shootout between brands... Innovative rated the highest especially regarding accuracy!

I put a bung on header #2. A wideband would obviously be best, but I'm just using a narrowband jet4power which works in a pinch. Just making sure it's not way off, and also it shows artifacts which can be due to crappy seals, poor spark and whatnot.



I'm using Keihin CV34 carbs on my 1983 750. I have the ones with the two mains, which I like because its primary main changes the meat of the throttle range.

Dave, i cant read this, can u post a link.
Thanks

r u saying that the analog is better than the digital gauge ?

Not more accurate, though it seems to be a servo driven gauge, so I would think it is very accurate.

Better for riding and trying to monitor the value without looking directly at it. Probably better in sunlight as well, but I don't know for sure how bright the digital ones are.

It's the same reason an analog tach is often preferrable to a digital one. With the analog, you can get a good idea of where it is just by the angle of the needle.

It let's you monitor the gauge even when under hard acceleration, so you can tell how your carbs respond to dynamic situations.

Thats good to know.
thanks.
