I hope you didn't order a slide off a KTM parts fiche....mucho bucks.
Sudco is tough to deal with, but check this out:

jet needle clip, 018-033, 16155-169-0040 , $1.38

My suggestion for dealing with Sudco is have an order like this and throw in all the jets you will ever need (forget the needles - unless you know how to translate between KTM's profiles and Keihin's) and make it a one time shot - they don't typically deal with retail customers and it shows on occasion.
Have your parts list, prices, quantity and credit card ready to go before you call (no web orders).
They handle Keihin and Mikuni so pretty much every BAP bike is covered.
If you don't have a large parts order, check out www.carbparts.com - not the best website, but they're a retail distributer - gotta call them too and they've got better prices than KTM's retail prices.
If you're just ordering jets (main, pilot, etc) - Rockymountain or your local dealer - if you're ordering needles you'll have to go to a KTM dealer - they're still not expensive though.
Yes, Kenny - they even have pink jets for your bike too so quit asking.
