The V-Star Strikes Back 

If I have a bike like this, the first thing I would do, if this hadn't been done already, is attach a fuel level gauge to each of the bowls while the carburetor is installed on the bike and see where the actual fuel level is. And if you can get the bike to be running while the fuel level of each bowl is being checked, so much the better. My guess is that the fuel level is way, way above where it should be. Adjust float level as necessary. That would be just the start. If that doesn't work, return the bike as much as possible to stock condition. There's been so much tinkering with this bike that it's impossible to figure out the main issue, or combination of issues. Also, hyperchargers may look cool, but I don't believe they do anything for the bike that would justify the expense.

My bet is the needles have something on them preventing the needle seat from fully closing. And my bet is when the carbs were cleaned the needles were overlooked as was the needle seats. I had the same issue with mine when i got it.

Synchronize the carbs!

sounds like stuck floats

Well the fuel pump is not working as it should. You can hear it trying to prime itself every time. That much gas from the exhaust means there is constant gas flow. Are the gas lines to and from the pump the wrong way around?. The easy way to isolate the problem is to bypass the gas tank and fuel pump. Just feed gas directly to the carbs and see what happens.

Your float needles are not seating right. They are not sealing off the flow of gas when the float raises up. Did you check the floats and make sure there was no gas in them? Even a pin hole in a float allows fluid in them and they will not shut off the gas flow. Your fuel pump always priming is the giveaway either the floats are bad or the needles are not sealing off with the float.

Change the fuel pump….its not regulating.

Am I missing something here.. You checked clearances and did the carbs. right !? The problem is somewhere in those areas..
