Charging Issue ..HEEEELLLLPPP
My 99 EGLIDE standard (12K miles) had a dead battery last couple of times I rode. So I just did a quick charge and went for a short ride. The last time I rode it had a bad misfire at 3K rpms and above I chalked it up to the bike sitting too long between rides causing batt drain and possible bad/old gas for the misfiring going on.
Today, I charged a slow charge all morning and my Voltmeter read 12.75 volts at the battery. When I satrted her up the volt gauge read just under 12V. This bike has always shown 13.5V charging on the dash volt gauge.
Correct me if I am wrong but if I am not charging when running it is getting all its spark from the battery causing the battery to drain. Also causing the misfire because there is not enough voltage to fire the plugs at a higher RPM?
Any suggestions would be helpful

First make sure all your cable connections are tight and corrosion free.
If your battery is over 2 years old, it's probably what the problem is. Especially since you say you've had to charge it to get you bike going the last couple of times you've ridden.
I had a Sportster that did the same thing. I took the battery to a indy battery shop. They checked it and said the battery was good that the problem must be in my charging system.
I decided to buy a new battery as that was the cheapest route and just might do the trick.
The new battery fixed my charging system! I never went back to that battery shop.

Just a guess, but I am betting the regulator is bad. It could also be the alternator. The manual has a good troubleshooting guide for that. Make sure all of your connections are clean and tight. Check the plug at the stator connector. With the bike running, you should have between 13 and 15 volts at the battery.

Put a good charge on the battery ,put the meter on the bat terminals and start the bike , rev the engine does the meter show voltage change ? if not probably the reg but check the wiring for breaks or shorts . If nothing found then you can pull the plug where the reg goes into the case and set your meter to AC volts and again start the motor and test the stator output it should read anywhere from 28volts ac up when you rev it carefull not to let test leads touch the case . No ouput here means shot stator if this is the case upgrade to the newer 32 amp system well worth it because of the pin / plug arrangement . Also if replacing the battery get a Harley or one of the " Glass Matte " gel types they are trouble free and usually last 5+ yrs . good luck bud
Check the plug at the stator connector
