Throttle position sensor is one of the inputs to the CPU on the fuel injection. It tell the CPU how far the throttle butterflies are open. The map in the CPU uses this input along with the others like rpm, etc to determine the fuel shot.
Not quite true, SW.
The bikes with K-TRIK (or whatever its called) has a throttle position sensor on the carbs. I know for a fact that the '00 that I tore apart has one, the bank of carbs is sitting in my basement witht he sensor still attached.
As for making an adjustment to provide better response, unless it is actually incorectly set, you won't beable to gain any performance by messing around with it.
I didn't do it, I swear.
And even if I did, what makes you think I would admit it to you?
