Lol story of my life! Well I just fine tuned my sync tonight and the bike runs like a champ! Btw, the threads for the vac ports are the same thread as a jet! I just threaded a jet into the other three ports that had bolts in them and hooked up my gauge set to them 
worked great, and you don't have to use the pesky vac sticks or buy or vac ports! Hopefully it will be a simple fix for ya!

I'm hoping so but after a little research non of the stores anywhere near me sell the sync tool. A friend of mine kind of has a shop but they don't have the sync tool (they're having a hard time getting their s**t together). So my only other option other than ordering one, which I don't really have the almost $100 to spend for a couple weeks, is to buy a single vacuum tester and do it the hard way checking one at a time, writing down what each one is at, then adjusting and rechecking from there. It'll be a pain in my *** doing it that way but the idling issue is killing me and I want to fix it now so I may just do it the hard way. Also I don't have any extra jets laying around so I'd have to figure something up on that too, but I'll get it done one way or another, the hillbilly ingenuity will prevail lol

Any bike will ride fine regardless of sync because you're opening the throttle to where air can come in! At idle though, if one plate is so far off that it fully closes and doesn't let the others come down to an idle state it can act like a dead cylinder! I'm not saying the sync is "only cause", just a suggestion! I've seen exactly what you describe on other bikes and a sync fixed it!

Problem solved, #1 and #3 vacuum ports on the head weren't plugged. Fixed that, started the bike up, now she's idling perfectly other than needing to adjust the pilot screw a little which is no big thing (other than #1 and #2 being a pain in the *** to get to with the carbs on). Thanks guys, I definitely appreciate all the input from everyone

Sounds like bad gas. This ethanol they are putting in the fuel is killing me.
Bike won't idle and stalls at lights. The ethanol is making it over heat.
Runs great once underway.
So....my advice is to empty the tank into your other vehicle and find a different pump before pulling carbs off.
If that's not the problem, you may have a vacuum leak.

Edit: What about the vacuum to the petcock? (mentioned in a different part of the forum) Without going out in the rain and looking, On should be up in 12 o-clock position. OFF is at 3 o-clock and RES is at 6 o-clock. I can't remember if fuel flows in the RES position. If so it would be easy to run a vacuum line to the petcock to turn fuel off when the bike is not running.

My carbs are in synch, I spent $100 on the synchronizer, so I imagine its decent. As was mentioned previously, the ethanol is terrible in general and particularly if it isn't fresh. Mine stalls at lights now, since its summer and hotter out and it keeps wanting to die unless the idle is around 1100, it would idle with no issue at 900 in winter. I even leaned out my idle mixture with no relief.
