basic gsxr throttle body questions
I am thinking that I want to put some gsxr600 throttle bodies on my 4age, so I bought a set without knowing anything about them.
Now I am looking at them and not knowing which way is forward (I do know which way is up!).
The biggest question, tonight, is about the butterflies, themselves.
There are two per body. Is one a choke? Never heard of a choke on a FI engine.
One set of butterflies is very easy to turn and the shaft ends in what I first thought was a very large Throttle Position Sensor. But now, I
don't thiink so. What is it?
The other set are very hard to turn (gave up trying - don't want to break anything). This shaft is equipped with what looks like a very small
TPS - am I right on this one?
These butterflies are very close to the injectors which, I am guessing, puts them closer to the valves.
Can somebody confirm/refute my assumtions, explain why those butterflies are hard to turn, and explain what that big thing is at the end of the one
shaft.
I will be getting a manual soon. But I will also continue asking here. Please bear with me.

I believe that the second set of butterflies are ECU controlled and help with part throttle air speed management
i.e. you don't need them, can remove them and should block the holes with something.
The 'large TPS' is probably some kind of electric actuator and would explain why the shaft is hard to turn.

thank you for the response. was confused, at first, because I didn't know what you were talking about "in your other post."
Further investigation shows that my finger must have "stuttered". oops.
the "large TPS" sure looks like a motor, but the butterflies attached to it are the ones that are easier to turn.
hmmmm. just have to take it apart, remove all the unneeded springs, levers, and such to see if the throttle plates will turn more easily. hope it
isn't stiff because something is bent.
