So if this is not my issue, what could also be a culprit. So when I start it up and get it warm, it idles fine. Once its warm, if I rev it, it will stay at a very high idle (showing full advance with a light) for some time and then will eventually go back to normal idle. While I was riding it, I would come to a light/stop and pull in the clutch and the idle would be at what I presume around 3k (it was almost like a nice cruise control when riding..haha). Once stopped, I would shift into first and engage the clutch momentarily to bring the idle down and then it would idle fine again sitting at the light.
On another note and possibly unrelated, while messing with the bike yesterday I had it just idling for a few minutes. I noticed that randomly every 30 seconds to a minute the bike would have a small backfire, stumble for just a second, then return to a normal smooth idle. I guess I was just lucky on my last XS that I got spoiled. I just cleaned out the carbs, set the mixture and never had another issue after that.
