I've been searching postings and have found a few about the Fat Duc. Since they were not strictly about the Fat Duc, I did not want to hijack the thread with my question.
The SF is my 3rd Duc and yes they have all had the lean, jerking, bucking, sometimes coughing/popping issues. I know it is due to the Euro 3 standards. The first 695 Monster ended up with the terms, ecu and open airbox on it for free from Ducati (because the leanness melted the paint off the engine) and it worked flawlessly. The next was a 696 that I had only for a year, so I never got around to fixing the the bump and grind of the engine.
I'm interested in getting the Fat Duc but can't get the company/individual to answer the phone or email.
I think it is an interesting take on adding more fuel to the cylinders but there is one problem (I think). So you add the Fat Duc, get it adjusted to your taste and take it for few rides. It appears that as you adjust the Fat Duc to add more fuel, the Lamda sensor's would detect the added richness and add (or subtract) more voltage. It seems you would eventually end up just where you started. I understand the concept but it appears that regardless of what you do to manipulate it, the lamda sensor is going to pick up on the richness (according to the map table) and adjust it again. Meaning that you cannot win.
Does this make sense or am I off into never, never land.
Understand that I'm not a mechanic so this is all theory in my head.
