Jetting help

I just got rid of my airbox lid with the help of a clamp on style adapter. I have a k&n and outerwears box cover. I purchased a dyno jet kit and I see clearly in the instructions my needle setting and main pilot size but the kit didn't come with any pilots jets. Its stock exhaust, do i need to up the pilot? What are the consequences if I dont. Havent run bike yet since I didn't want to tear bavkndown if I need a new pilot.

if the pilot is too small it will be boggy and hard to start. if all you did was the air box and not the pipe you should be ok. if you need a pilot jet you can get one at rocky mt. if you do just go up one but i think you will be fine.
