Also piston crown and head will tell you how your jetting is. with 50/NP3/185 you are good so far I can tell.

N3EJ Needle, start at #3 slot,but may need to go to #4.
That bike, especially with the SST pipe, requires that you keep using that good gas, or it will detonate alot when under a load.

Premium from the pump was not working good so I started to mix 50/50 with Sunoco 110
40:1 motul 800, stock pipe
Slow vet C, Mx only and stock jetting works pretty good on mine (48 pilot/178 main and N3EW #3)
It's a tad rich and I might play this setting as it's getting really warm and humid but shouldn't be to far off from current settings
I couldn't get my jetting right when using only premium for the pump. I met a fast local on the same bike who told me about adding a bit of 110 and it did the trick.

With the SST pipe guys are usually ending up with a little bigger main than most. Also, the porting thing can throw off jetting. You need to do some WOT chops, plug readings, etc, and determine what your bike needs. Might find lots of guys running 175 mains, but with stock pipes and porting, and going from a 185 to a 175 might be death for your bike, or perfection.
RiderX - like arnego2 said, a few minutes of street riding and using the bike under actual riding/racing conditions will bring you very different jetting requirements.

I rode all day Saturday and the jetting worked great. I started at 1 turn out on the pilot screw, which seemed to load up a bit at idle after the motor was nice and warm. I ended up at 1 3/4 to get it perfect. It ran flawlessly after getting the pilot screw dialed in. It was 100 degrees here and very dry. Where I rode was at about 800ft. No spooge. This bike rips, way more lively than any KTM I've ever owned (I've had 5 of them).
