The thing is with this fault is that for many of us it is speculative,as we are basing our judgements on posted symptoms without a troublesome bike to apply the theories to .There is also the possibility of more than one common cause (not the mention the seemingly random ones... e.g. my coolant temp sensor terminals were not both locked in correctly ,finally causing it to run rugged ,not a difficult one to trace ).Based on what I have read and seen I think for the most part that the fault is in the ecu ,but my bike is ok at present so there is not much to follow.The point is either way ,it is TRIUMPH that need to sort this crap out,and our energies should focus on getting them to do so.
