How To: O2 Bung Install.
Hi all, I just did my O2 bung today and took some pics along the way, so I thought I would make a "How To" on the method that I used.
I think that it is becoming more apperent how important it is to measure AF with the problems that a few have been having getting RRFPRs to work as they should amongst other issues with fuel pumps ect ect. This could go undectected without proper testing and cause major engine failure.
So 1st off it is important to decide where you want the O2 bung to be. I got the Innovate LC1 Kit and in the instructios it says to avoid putting the bung at the bottom of the exhaust pipe, somewhere between 10 and 2 O clock is where you want it. This is because of condensation which is less of an issue with running them in the J pipe coz it will not be permantly installed just fitted for testing then replaced with the bung for genaral riding. Your second consideration should be access, you want to be able to get it in and out easy.
So with your spot choosen, I got an 1 3/16 hole saw and cut through the first layer of the jacket.

With the Outer layer cut you then need to drill the actual exahust with a 7/8 hole saw. I then used a large ball pain hammer to bring the outer layer toward the inner exhaust pipe.

Now you need to have the 2 layers welded together, A good TIG welder will be able to do this for you.

Once this is done it is time to weld the actual bung into the exhaust, this maybe a little tight so file to fit. This needs to be welded all the way around to seal the exhaust again.

Finaly I had a little trouble with the bung itself It was welded with the bung installed but i think it still distorted abit and so did not want to unscrew. It did come out but left abit of damage on the threads so i had to run an M18 x 1.5 tap through to clean it up. I hope that this helps any1 who needs to have this done. I dont mean to re do anything that has already been done but i could not find much with pics to explain on this method of doing the bung install.
Now then boys what you think of my bung hole??????

That's how I do it, except I heat the surrounding metal up with a torch to get it soft before I hit it with a hammer...that way I only bend what is close to the weld
