I like the sound of this! I have a 2005 1200GS as well as a 2007 Ducati S4RS Monster. The two cylinder Ducati was TERRIBLE below 5000 RPM and it was due to the fact that the bike was on a closed loop ECU system below 5K (or 4K, not sure where its is set). In a closed loop, correct me if I am wrong, the engine Fuel/Air mixture is dependent on the data from the O2 sensor. There is really no "data" sent from the sensor. All the O2 sensor does is send a different level of voltage to the ECU and the ECU adjusts the fuel/air mixture depending on the voltage the O2 sensor sends. I bought a very simple solution from the folks at for my Ducati. $80

The O2 manipulator installs in line with the O2 sensor between the sensor and the ECU. It is a very small voltage regulator that you can manipulate via a small screw on the wire to adjust the voltage sent to the ECU "Tricking" the ECU into thinking it does not have enough fuel. WOW! as soon as I installed the manipulator on the Ducati it was a COMPLETELY different bike!
O2 Manipulators are an economical solution to alter the closed loop air-fuel ratio on many Ducati Motorcyles. O2 Manipulators are “plug and play” requiring NO cutting or splicing of wires and installs inline at the factory oxygen sensor connection. O2 Manipulators work by altering the oxygen sensor output voltage. This slight reduction in voltage forces the ECU to add additional fuel.

I am emailing fatduc now to see if they can make one with the connectors found on the 1200GS.
