Jetting help

I have been working on the jetting on my KTM 06 250 SXF... I see a few people mention the needle position clip (#3 to #5 and so on) I have adjusted this but not real sure what this adjustment does. The main problem I have now is when i blip the throttle it idles high for 5-7 seconds.

The altitude here is 3800 feet. I would like to know the FACTORY jet sizes.

To start with...set your pilot fuel circuit as per spec. Loads of threads/stickies on how to do this properly. Once done....go from there
