You have to pull the gas tank off. There is a gray/red hose, you'll see it on the left side of the air inlet. Tee into it, and connect that piece of hose, run that to the nipple on the HC, that will operate the butterflies.

hello DaWay.
I have a hypercharger installation problem, and is that the butterflies
stay open all the time by any chance do you know how to solve this problem?
Any help thank you
