bought a new battery wont turn over still it wants to but it struggles. Check the spark plugs they seem fine not even a couple Months old. They do have black on the ends... it had a high idle problem so i took the intake mainfold and reinstalled to fix it. Fixed the high idle and Thats when my problems started to happen. What else can i check os. I checked the new battery just now and i realized that When I tried to turn it over the voltage dropped to 11.9 volts what could cause this significan drop
Read the last line in post 8 but add "When cranking, the battery voltage of a good battery should NOT drop below 9.6. If it does, the battery needs replaced." Sorry

What is the battery voltage without draw i.e key turned off?
If you have a battery tender, charge your battery until it is fully charged. Hard to assess if you do not have a fully charged battery. Some new batteries are not fully charged when you get them....had that happen to me and a friend. My friends bike was new too and he couldn't get it to start. You can then test your VR/Stator when the battery is fully charged.
Popping could indicate an intake/exhaust leak but would lean towards an intake leak since you fussed with the manifold.
How did you test spark....did you pull each plug from the cylinder one at a time, reinsert plug into the spark plug wire, touch the plug on a ground source like the heads, then turn the motor....you should see spark on the plugs. Caution when doing this be sure to cover the plug holes because you don't want fuel shooting out while you are testing spark.

spark is good checked it that way. Battery fully charged. Compression at front 180 rear 210 checked fuel line by dissconecting fuel line and the connection that goes to the mainfold good steady stream came out. What do i check next? Trying to upload a video but cant or audio

Sorry did you say it turns over or it does not turn over?
Did you check the fuses and relays as suggested by Shanneba in post 4?
Another fuel check.....take off the air cleaner, turn on the key, and check if you see fuel shooting into the throttle body when twisting the throttle? If not, try shooting carb cleaner while starting to see if it starts.
Again, process of elimination.....but answer to the first question will kind of determine where to focus so you do not bark up the wrong tree..
A 2009 Sportster should be EFI and you will not see any fuel sprayed in the throttle body when twisting the throttle.
Seeing fuel come out of the line makes me wonder if maybe it was converted back to a carb.
The EFI fuel line has a check valve and fuel does not normally flow when it is disconnected.
Does your fuel line have a quick disconnect at the gas tank?
