883 Hesitating after warming up.

Brief History:
We just bought a 05' Sporster low with only 4000 miles that sat since November of last year.
The question or problem we face is hesitation in just 1st gear. All other gears the bike runs great and it only starts to act up after about 20 minutes of riding. It starts up fine, runs fine the first 20 minutes or so but soon as the bike is hot it starts to hesitate from stop or down shifting into 1st gear. I can shift into 2nd and 3rd gears and it runs like a charm, no issue. I just spent $100 bucks to have the carb cleaned and jets cleaned out but it still hesitates.
Not sure why the bike does this after runing so good for 15-20 minutes without a issue.
Any ideas what else I can have checked?

Do a quick search on the site here. Basically you take WD40 and spray around the intake seals note any change in idle. I have been told to do this when it is warm as well.

My guess is seal at the carb where it slides into the manifold.

Also, if you have the plastic inlet elbow it may be cracked. Do you have strong fuel smell or notice any small leak near the fuel line at the carb inlet? When mine cracked it would leak just enough to cause some stumble.

Okay I understand your train of thought...
But why would my bike act up "after" about 20 minutes of riding. The first 19 minutes of riding the bike runs great. (And hesitates only in 1st gear)

This issues has me baffled.

Ckp could be going bad, do a search on here about it, been covered a billion times, check for codes as well, there is a sticky on that procedure here as well.

well the only thing that has any hands on it is the carb and all of the attachment points.

Yes Jimmy is correct, could be Ckp

Not sure what you mean? Run codes see if anything pops up. 04-06 sportys are notorious for having ckp issues that give rough idle and hesitations off of idle. But yes you should check for an intake leak as well, simple quick and you can then rule that in or out.

Just meant the only thing that was done recently was carb work according to OP. That is why, but maybe they did not even pull it to clean it.
