Plumer and Thunder - you guys are hired as my lost wheelie detectives - you are really digging into this - thanks. So yes I closed the clutch switch permanently by connecting the two wire going to the clutch switch. My shop manual says nothing about the clutch switch affecting the ECU map, just when the starter will engage ( when clutch is in if in gear and kick stand up (always up as I by passed that also)). I'll try opening that circuit, but I am sceptical that the ECU map will change - only because it seams the full service manual would list that as a possible fault for poor performance. Now we need to know why the B/Y informs the ECU....I think it is just a safety feature - but we will find out. But keep feeding me ideas - I have a list from OHJim I working on. Yes it does - As a last resort I supposed I could go to them kicking and screaming - I'm a man I don't need no help - NOT just a man - an Engineer!
