vacuum check

[stangcrasher]

Ok so heres the deal. Got a hypercharger, hooked it up started the bike. Butterflies only close about halfway, and flutter like crazy with the lope of the engine. This makes a ticking noise and is very annoying. Called tech support at kuryakyn and they said check the vacuum. Put a gauge on it and the needle flutters just as bad as the butterflies. Now heres where i get real confused. Bike idles down nicely just like it did before. Runs great, no hiccuping or hesitation. if you pull the vacuum line off, idle rises as it should, plug it with your finger and you can feel the pull of the vacuum, but pulsing. I know i didn't pull off any other vacuum hoses, besides the one that goes to the vacuum body that activates the reed valves, which shouldn't effect anything since these are marbled. Does anyone have any idea what could be causing this? I'm stumped!!!!!!!!!!!!!!!!
