I couldnt take SO much for it as it is an ENGLISH bike, I could take more than 140 GBO, too bad guys you missed out on a bargain. Thanks guys, I NEARLY sold it to TP
Likely to be sensor plugs where lambda sensors go in (as Demon says)........look at (left or right, can't remember which) exhaust under engine........happened to me and caused same confusion. The plugs are made of different material to exhaust (!) and therefore when they get hold and cold over several hundred cycles they work loose.
