Installed a Vance and Hines shortshots staggered system, Vance and Hines fuelPak, and a K&N stage 1 intake on. Now the check engine light comes on and stays on. The bike runs great!!! Ive check the codes and come up with P0051 which is a rear O2 "open" ....and It wont clear. Does anyone have any ideas on this????

 

Same thing just happened to my Lo. Take it in and they will warranty it. They did mine.

 

Did they tell you what the problem was?

 

Just had the same code pop up on my 2012 Fatboy Lo. I have the V and H Big Radius 2 into 1 installed.

 

Its an o2 sensor code.

 

Any word on if it's just a defect in the 02 sensor or if the V and H exhaust could be causing the sensor to go bad.

 

At the shop now....will let you know what happens.

 

Rear O2 sensor that I already knew was bad. They asked if I got anything on the sensor while installing pipes, I told them no. So they needed to order the sensor and I go back in to get it replaced under warranty next week.....

 

Could be an exhaust leak. I got a front 02 code when I installed mine. I put in new screaming eagle gaskets and was more careful when I installed and torqued the second time. No more code after that. If you don't torque the flange nuts correctly you will get a leak and a code.

 

My code ended up going off after I tuned back the tuner a little bit. I tuned it back went for a hard 60-90 mph ride on the interstate and the engine light went out on its own.
