Need some help installing a used hypercharger on a stock 1995 fxsts. I bought it off ebay and I have no idea of how the butterflies work. Can someone tell me where the vacum comes from to operate this, and how to hook it up? Do I need a crank case breather kit?

 

I think you will need a T and tap off of the carb vacuum. Go to the Kury hypercharger web site. They have instructions there.

 

1st HD is correct....there should have been instructions on how to do both the carb and fi types of hypercharger installs....the carb one has a black plastic T whereas for my installation just see the pics....the vacuum gets attached to the throttle body under the map sensor...
