Idle/Air Adjustment Problem

Hey guys! I installed the Vance and Hines Cruzers a few days ago and really like them! Only thing that bugged me was the popping sound when I let off the throttle, so I did some research here as usual. I read a lot of people said to adjust the idle/air adjustment screws to reduce the popping.

Anyway, I took off the caps and screwed them all the way in. Then, I unscrewed each 2.5 turns out. When I started the bike, the idle was VERY low. After about 10 seconds it died.

After this, I adjusted them to the point where the idle started to raise, then I adjusted the idle. It seems to be running fairly alright, but right now the screws are under 2 turns and not evenly twisted on each side.

I'm not that advanced when it comes to mechanical things. I installed the V&H exhaust, and adjusting these screws seemed easy enough. I just don't want to cause any harm to the bike. Can someone direct me as to how to properly adjust these, or should I take it to my mechanic for ease of mind? Thanks.

ride for a bit and check your plugs. There is really no uniform adjustment for carbs. If your plugs look good on both cylinders leave it alone. If they don't adjust accordingly.
