i am trying to rejet my 2005 400ex and have run into a problem. it has the stock keihin carb but does not have an adjustable needle. it only has one slot. do i need to buy a new needle or is this supposed to stay like that.

You can buy an adjustable needle from Dynojet. Probably your best bet if you're rejetting. Good luck
