I believe the disc's allow more flow. So the more disc's, the louder it gets, along with a power increase.

If your jetting and airbox is stock, 4 discs is fine. Adding more will do nothing but make it louder
When you open the airbox and re-jet, you can go up to 12 and you will feel it. I would use 10.
Put the discs in after you jet, so you can feel the difference.
Use the red needle on the middle setting, one size larger pilot, and a 160 or larger main.
