Euro bike error code 24

has any european wrr owner come across error code 24? the fazer forum says this is to do with O2 sensor but i am not sure if the ecu codes from the fazer are the same as for the wrr. I removed the O2 sensor when i removed the stock exhaust/header, so i am clueless as to why the light would come on now, a year after the mod? i cant locate the cables that attached to the o2 sensor anymore and there is no wiring diagram anywhere on the web
thanks in advance.

Can't answer your question about the code 24. But here is the wiring diagram...
