They need to be sealed with a nice newish round o-ring . see full story at cycleorings.com

I checked all the boots and o-rings and there is no leaking there at all. Vacuum lines are all good too. I checked the plugs and they are black and sooty. Dry. From what I know that means I'm running rich. Any ideas?

If the advance mechanism is sticking it can do that too.

Take the ignition cover off and twist the advance unit by hand. It should turn clockwise and spring back pretty quickly.

First, did you actually remove boots and make sure o-rings are sticking above boot surface so they can compress and seal (the hanging idle stuff) ?

Second, you said this "....I did notice tho when I was trying to adjust the mixture screws that when I seated them (lightly seated) the engine didn't sputter or die. " to me, this suggests your idle passages aren't completely clear and youre compensating with throttle plate positioning to add mixture.

Could a loose exhaust valve cause the hanging idle?

You haven't checked the valve clearances yet?

I just did and the one exhaust valve was a bit loose. I did the whole works on the bike last year around this time and everything was good. That's why I never checked it. I figured it should've been ok still. Guess I was wrong. :-(. Think that May be the culprit?

No .

Well. Damn. Idk then. All my vacuum lines and fuel lines are new. O-rings at the intake boots are good. Airbox side and the engine side boots are not leaking. Did the spray test. Not the cable. It's brand new and even tried it running without the throttle cable hooked up. Took the carbs apart to see if there was a passage that was blocked that I may have missed when I cleaned it but everything is clean as a whistle in there. Could it be a jetting issue? PO put header wrap and slip on hi-flow mufflers? Possibly bump up the pilots? It has the stock airbox on.

Is your choke sticking open? And are the carbs balanced?

I'm wondering if one butterfly is opening a lot more than the other can it cause this?
