Does anyone know the easiest way to adjust the headlight?? I looked at taking the underside off of the nose, but it looked like I need a special tool to get those plastic rivets off of it. I also need to know the easiest way to adjust my idle. I'm around 1000 and it dips below every now and then. The only thing is that it doesn't die where it's idling now. I know it needs to be a little higher because it sounds terrible at idle.
