Hay guys, i have a new pro rmk 800, i have a like new wideband o2 sensor and all the wiring and gauge, looking to mount it on my stock can. I will be running a aaen pipe, with no controller, that is why i want to run the o2. so anybody have an idea of where to put the sensor any help will be great thanks chris.

The stock pipe is where I've put it for a few years. The silver pipe is where a buddy installed it after a quick phone call and some begging. The silver pipe comes out and goes back in easier with the O2 installed.

Thanks Rick! how so you put the o2 in the pipe not the can? what about gettin raw gas on it, it doesnt throw off the reading or does that part of the pipe not get any raw fual thanks chris also thanks for the pictures.

Thats a pretty good spot, the 10-2 O-clock position is best as gravity helps keep oil, fuel and moisture off the sensor. The last recommendation I saw from NGK was 10x the diameter of the exhaust outlet. If your outlet is 2", then 10 x 2=20. So at least 20" from the exhaust outlet. This can be difficult on a 2 stroke, especially if you are boosted. Should not mount the O2 sensor on the pressurized side of the exhaust turbine, will shorten the lifespan. Raw fuel (too rich), too much oil and too much heat will also shorten the lifespan of the sensor.
