I have an 05 883, DK air cleaner, Cycle shack pipes, I am running 175 main, 44 idle, screw 2 3/4 turns out, CVP velocity needle, and emulsifier tube. I get an occasional stumble at idle, and dieseling at shut down. Other then that is runs like a champ.

Took air cleaner off this am to clean, and the inside of the cleaner was wet and had a small puddle of fuel, fired it up with no cleaner, knowing it would be lean, and it seemed like there was some blow back coming back out the carb, a slight mist of fuel coming back at me.

maybe cam timing of a tooth? burned valve? or just me being paranoid?

 

Probably a good idea to double check a few things?

Your answer is in the sticky in this carburetor section at the top of the page, look at post #4 but not a bad idea to read the entire posting. YD

That is most definitely NOT running like a champ! If you can't sort it out soon, find yourself a local indy to tune your bike properly and resolve any running problems with it.
