2012 te310 "fail" code after performing power up

Hey everyone,

I recently performed the power up kit for my 2012 te310 which included the following:

-Remove throttle stopper plate.
-Replaced air filter cage.
-Removed O2 sensor
-Removed catalyzer

Now on start up I get a "fail" code which blocks the right side of my speedo. Anyone know what's going on here? It was my understanding you did not have to get the 2012s remapped because of the blue button they give you that switches between race 1 and race 2.

I appreciate any help here. Thank you.

Check you have battery screws well tightened and/or O2 sensor eliminator well plugged.
I once had a 'fail' code in my display and bike failing .. and it was battery's positive screw loose ..

did you remove the O2 sensor and put the jumper on the proper conector to override it? or just removed the sensor?

You need to put a jumper on the terminal, if not, that could be affecting..

Thank you for the replies. The O2 sensor was removed and the terminal was plugged with the jumper. Any other ideas?
