When adjusting the TPS on a '99 R1, I know the TPS must be plugged in and the key must be on. I know the bike tells you which way to adjust the TPS via the tachometer.

But in order to install the TPS, you must remove the carbs, so I imagine they still have to remain off while adjusting the TPS. Am I correct? Or is the TPS like a tilt motion sensor (when you move the throttle cables, it tilts the TPS one way or another), and the TPS must be adjusted with the carbs on and completely upright?
