Thanks for the reply, I have a GS911 hence could identify the fault code so don't need the dealer. Anyway just disconnected the sensors and seems to have sorted the problem. Not my bike but he had a choice £130 for new sensor of just ditch em, it's what I would have done but just wondered ig anyone else on the 1200 section had already done so.
Like I say no problems on my 1150 so fingers crossed should not be problem on the 12, not bothered about the fault codes
