Iconic944ss,
  Spoke with Neil this morning....  
 It transpires I don't have any Lambda's sensor on my bike...
   I can only assume it has had a termi systems on it & the previous owner has removed them.. as were they should be I can only find some bolts....  
 Do I need to get hold of any? 
 or once I pick up a Zard Full system, will there be any need for them... 
 Cheers for your help thus far...
