I have a 2014 SG and installed an RC Xhaustset of slip ons, decatted the head pipe and some V-IEDs. It was running great with just the VIEDS but once I decatted the pipe, it started acting funny. I thought it was a bad ground so I switched it, problem didn't go away. So I pulled the code and it was showing a 132, cleared it and then 131 came up. Removed the VIED completely to see if that was the problem, ride it for 20 minutes and it was very erratic and crazy. Now showing codes 131, 132, 151 and 152 so it seems my O2 sensors are crazy. Any ideas? I might swap out the decatted pipe for one with a cat and see what happens. Suggestions? Oh and I know I went the cheap route on my expensive bike but I'm just trying to get some help.

 

Maybe you damaged one of the O2 sensors while swapping. Check all grounds, make sure you didn't hook the sensors in the wrong spot. If that doesn't do it I would put the stock pipe back on and try that.

 

Sounds like you got your O2 sensors swapped and in the wrong holes. Double check that you did not get the fwd cylinder in the aft head pipe and ....

 

I made sure the plugs match colors but I may have swapped them. I saw someone say black to back and that is the way I have mine. Is that correct?

 

Correct, black is the back cylinder. this is the top / upper bung hole on the stock pipes.

 

 

Sounds like the "crosstalk" between the sensors that has been mentioned in the discussion about de-catting the head pipe.

 

Yup. That was the problem. Thanks'

 

Mine was delivered from the factory with those symptoms; HO2's were in the wrong holes from the factory.
