SECONDARY THROTTLE CONTROL SYSTEM
The secondary throttle control system (STC system) consists of the secondary throttle valve (ST valve),
secondary throttle valve actuator (STV actuator) and secondary throttle position sensor (STP sensor).
ST valve is installed in each throttle body. STV actuator and STP sensor are installed on the right side of the
throttle body assembly. The ST valve is turned by the STV actuator.
This system is designed to control the volume and the velocity of intake air so as to improve engine output
power. The system produces more seamless and linear throttle response.
This is performed by opening or closing the throttle body intake port according to the gear positions and
engine rpm.
When the engine is running in a low speed range, the intake port is almost closed for controlled intake air
volume. This improves the effect to intake air flow pulsation so that the engine can output higher power in
this speed range.
As the engine speed grows faster, the intake port are gradually open for guiding the proper volume of air
into the throttle bodies so that the engine can produce the maximum power in each speed range.

I am having a problem with a 2000 750 that is very similar to yours. All my asking around has yielded nothing. From what I have been able to figure out, I believe it is the small ecu box located next to the rectifier. Part number should be 32910-39F00. I just need to know if the 750's use them also, and what part number for a 750.

Mmmm, maybe on the right side of the throttle body assembly?

On the side of your throttle body is the stv actuator. The control box is in the tail. You may have to remove the tail fairing to see it. It should look like the one pictured in this link.http://cgi.ebay.com/ebaymotors/01-GSXR-GSX-600-750-MIKUNI-TROTTLE-CONTROL-UNIT-CDI-ECM_W0QQcmdZViewItemQQcategoryZ35594QQihZ003QQitemZ130276118622QQrdZ1QQsspagenameZWDVW
