Strange Problem.
I get a buck/cough in 1st gear sometimes. It only seems to do it in 1st and not all the time. I am not sure if this could be an engine cough or a clutch problem. It happens when I pull out from somewhere. It will buck/cough then go. My sportster is a 03 883. Is there a problem like this they are known for? Thanks.

Does it sound like its coming through the air filter? I have been experiencing something similar on my 2006 1200. It burps through the air filter, lugs for a second, and then goes.
I've read a few threads that seem to indicate it may be a "lean" fuel issue, but I haven't really been able to follow what adjustments are necessary to resolve the problem. I am considering adjusting my enricher retention screw out to allow for more fuel flow, but am concerned it may burn up the spark plugs and do damage to the engine. I need further advice as well.

Air filter Has oil all over the bottom and the plastic is soaked with oil. I did the oil change by the book. Up right on the stick is just over halfway. Can I just remove some of the oil from the tank. Maybe 1/4 mark on the stick warm? The stick is a type that shows the oil temp on it. Would this cause a carb fart while I am trying to tune it?

Just had a though. Charge the battery overnight and see if it goes away. I have a short (4 mile) commute to work and mine would act up a bit by towards Friday and then got better after a weekend riding, it did seem to go away after I got my battery tender.

I am an x-ricer and this is my first Harley. I don't understand how a oil tank can be to full and do this. Can you explain this to me and keep it simple to understand? Thanks.
I updated the other post above. I had to pull the filter to see the oil.

EPA mandates a closed loop for the oil breather. In stock form it burps excess oil out of the crankcase into the airfilter cavity if you overfill it or let the bike sit too long and the oil settles down into the crank.
I am pretty new to HDs and Evo motors but on my Enfields they work on a dry sump with a scavange oil pump. On them the breather is pretty important to keep negative pressure in the crank to reduce pumping loss, I believe it to be the same with the Sporties since when I had the rocker covers off they appeared to have a breather valve built into them.

Cleaned everything up and put it back together. I re-adjusted the carb and took some oil out of the tank. The oil is at the 1/4 mark on the stick now with engine warm. Went for a ride and the engine seems to be alot smoother now. I will have to run it for a week and see how it does.
