883 Hesitating after warming up.
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?
