hi
have a hayabusa gen1 which still has pair valve fitted. A small vacuum that runs off the top of it, where does it go?

It is fed from one of the vacuum take offs on the throttle bodies. There are 2 take offs per cylinder use just one, anyone. The other take offs should all join together and go to the MAP sensor.

Thanks mate, its been cut short so wasn't sure. Think its time I invested in a manual!
