2012 Fat Boy Lo problem code
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????

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.
