But that's the point, the pulley on the TB isn't directly connected to the butterfly. The throttle is only connected to the brain. This is not the 'simple' bike some people think it is. Ride it and enjoy but it's not a mechanical throttle, it's simply not practical with EURO4 regs.
You need to do better than "assert" the pulley on the TB isn't directly connected to the butterfly DervMan. On it's face the statement makes no sense; what else would the pulley on the throttle body be connected to if not the rod to which the butterflies are attached, and which causes them to open and close and engine speed to increase and decrease? Further, if I read the parts microfiche (THROTTLE BODY section) correctly, the cables from the hand throttle do connect directly to the throttle body pulley, on the right hand side of the TB, just where the butterflies are located. As for the throttle cables, they are both one piece and don't seem to have any connection to the ECU (brain). Unless you can show where and how that is not so, I believe Beamer has it right. your dealer has it wrong; the Africa Twin does have a mechanical throttle and is not ride by wire.

Your dealer might have misinterpreted the function of the idle air control valve assembly set (assembly), which has a "motor" but the motor regulates air needed by the engine at idle. That motor is probably controlled by the ECU but it is not connected to the butterfly rod or plates and would have no effect on engine speed other than at idle.
