Sportster Crisis -
Did the problems occur prior to the install of the AN BS and the PC V.
Start the bike, let it run a minute, shut it off, wait 15 seconds, then check the dip stick. That is the first thing I would do.
Regarding the battery, either the connections are bad, battery is bad, stator is bad or regulator is bad, or some combination.
But you gotta address one thing at a time, and then go step by step, using a process of elimination.
Before I did anything else, I would make sure the oil level is safe, using the process outlined above.
Then if you let us know if the problems of misfiring - engine running poorly, were occurring before, or only after AN BS AC & PC V install, we can go to the next step.
I would suggest getting a service manual also.

Thanks for the tip dude. Unfortunately I can't crank it now. I'll have to go have the battery charged again. Or get a new one.
I'll keep you guys posted as I move through these possible solutions.
If anyone has more input, it's still greatly appreciated!!

Ok, the engine misfiring was occurring before the PC V and A/C install...then you can probably rule those out as a source of the problem.
Once you get it cranked, so you can properly check the oil level (and adjust if necessary), the next step is to find out if you have a bad battery or something bad in the cables and/or charging system.
Then, after that, when you can crank it at will, and know your oil level is right, that is when you can start trouble shooting the engine.
So I got my new Yuasa battery in today and it cranked up like a dream. Here is a video of the bike running and a brief explanation. Vid is 45 sec.
Something I noticed when i got back on the bike was the Battery and Check Engine light were both back on. Could this be an issue with the charging system and not just the battery?
As for the oil on the engine, I have no clue how it got there. Maybe a bad gasket from the low oil? Should I just wipe it off and see if it appears again?
Other than these issues, its running fine so far. Only hiccups for about 30 seconds now and runs fine after. Could this be from a coarsely tuned PC V?
Thanks guys!

Does not sound like it is running right.
If a new battery is already low, that points to a problem in the charging system.
I would either get a Service Manual and start going thru it, step by step, or take it to an mechanic that has a good reputation with Sportsters. I would not take it to a Dealership (unless they have an actual mechanic there), since they have "Techs" at most dealerships now, which is just a title for a parts replacer.
btw, did you check the oil level per the procedure listed in my above post?
Also, threw on some lowbrow customs plug wires and its running a bit better it seems.
But whats up with the oil?
Im curious if all of the oil didnt drain? that would explain why the new oil is already black. What do you think?
I think it's a combination of several issues. But agreed, it's just about out of my hands on this one.
No joke though, I thought working on a harley would be easier than my sport bikes. Not the case!

Replace you battery as since it won't hold a charge. Bet it will solve most of your problems.

I think you need to check your oil before you do anything else. It sounds like it is way overfilled.
Use a turkey baster to get a bunch of it out, then check it and delete or add as needed, per the manual.
In case you don't have a manual yet (you should get one) here is what it says about oil levels.
"The correct oil level should register midway between the FULL and ADD marks on the dipstick.
If oil level is at or below the ADD mark, add only enough oil to bring the level to the middle of the two marks on the dipstick."
Until you get that right, the bike should not be ridden.
Also, another thing that can happen with an incorrect oil change on a sporty is something called "cavitation". Another reason to get a manual. It is not a matter of just pulling the plug, draining the oil, replacing the plug, and dumping some new oil in.
