On most bikes the throttle position sensor is on the throttle body, coaxial with the main throttle valve. Tap into the lead that connects to the wiper of the pot - this typically shows a voltage ranging from just over one volt at closed throttle to 3.5 volts at full throttle. On newer Yamahas with YCC-T, connect to the sensor detecting twistgrip rotation, not the one on the throttle's butterflies.
