I have a set of throttle bodies off a 2003 R6, for my EFI 2 stroke atv project. What is the small cylindrical item located above the bores in the center of the picture? It has a spring attched, and operates some type of plunger on the side of the throttle bodies. Trying to figure out if I need to keep it or not. Thanks guys...
