11.1 How to perform a TPS reset
(This chapter applies for models with DDFI-2 injections only. Models from 2008 and later are usually
equipped with DDFI-3 and do not require a TPS reset done by a computer any more.)
On the front left of the engine, between the airscoop and the engine, is the idle adjust screw, which
simply adjusts the butterfly in the injector to allow air through for tickover.
• Connect the bike with the computer
• Turn ignition on and set kill switch to the run position
• Turn out this screw until the throttle voltage doesn't decrease any more
• Keep winding the screw two additional turns
• Close the throttle with light clockwise pressure on the throttle grip. The butterfly is fully closed
if it sticks inside the manifold. It's essential, that this is done whith care, as the TPS reset
needs to be done with the butterfly fully closed!
• Click the "Reset TPS ..." button to perform TPS calibration
• Turn idle adjustment cable clockwise until TPS degrees read 5.2 - 5.6 degrees. This setting is
just to make the engine start and needs to be adjusted to correct idle speed with a warm
engine afterwards.
• Run vehicle until engine temperature is at least 140 °C or 285 °F
• Set idle speed to 1050-1150 min -1
