4 turns out on those idle mix screws is too much in my opinion. Should be 2.5 to start with then make very small adjustments from there. I'm talkin 1/4 - 1/2 turn and wait a couple of seconds for change then another 1/4 - 1/2. I got mine to idle beautifully by going slowly with the adjustments. I'm probably at around 2 3/4 on one and 3 on the other but I also changed my jets. If you're running the stock air cleaners (ears) then yours would probably be a little less. You asked if they should be the same...They don't need to be exact but they should be fairly close on an engine in decent condition.
Sometimes people run the idle too low on these v twins because they sound cool but they're not designed to idle low. Oil pressure will suffer and it won't charge right. May even foul up a bit if too long, like if you're in traffic a lot. They're supposed to idle at 1100. Just putting it out there in case, since you haven't had it long.
When it's idling does it smell if you stand behind it? That's a good indication that it's rich. Hope this helps. Update when you can.
