Topic: Need some carb help -- WITH VIDEO

cart before the horse, man.
how will you use a vacuum sync if you cant get your bike to idle? 
even with a bad bench sync, your bike will idle.   
a vacuum sync device will not help your bike to idle well if your air fuel mixture is not close to being correct.
if you bike wont idle right now, your air fuel mixture is still off.  (pilot jets and mixture screws)

needle clip position can change and your bike will still idle. 

maybe this visual will help wrap your brain around it.

It's high time I updated this thread. So it turns out that my issues with tuning the bike ended up being bugerred emulsion tubes (I'll get some pics up of them later). Along the way somewhere someone had hammered the tubes out and destroyed the inside.diameter, thus allowing different amounts of air/fuel to flow between the carbs.

Well after sourcing a used set of emulsion tubes from a guy on ebay me and a mechanic friend were able to get the bike dialed in pretty close. I ended up putting the stock air box back on to eliminate the K&N filter as a tuning variable and the way the bike is running right now I doubt I ever put the K&N filter back on.

The setting we ended up settling with are:
38 pilot jets
115 main (will do a plug chop later to confirm it's not too rich, but for now runs great)
Needle clips in 3rd position
Screws at 1.5 turns out

The bike takes off from idle without any hesitation now, and runs strong and smooth all the way to redline in all gears. The revs don't hang up anymore either. Needless to say I'm extremely please that for the first time since owning this bike I can finally rack up some worry-free miles.

That's good, there are a lot of people trying to bypass the emulsion tube issue and instead try and correct the main jet and slow jet to significantly outside of spec.  It is a band aid that helps but not a real fix like you are experiencing.

This is also why I have turned away some jobs that are disassembled already, it's not a plus, it's a negative, if done incorrectly, the emulsion tubes (which are in fact a jet!) are easily mushroomed and damaged.  A set that has never been into before is always better/preferred than rebuilding an already "rebuilt" set.
