They have their own needle..
150 main
125 pilot
3 turns out on the air/fuel..
This is a slip on setup with the lid off the air box..
Hope that helps.. You can specify what jets you want though..
IN the comments section just put what main, and pilot you want and they will send those..
It cost me like $27 with shipping for the jet kit.
You cant go wrong there. I'm not sure how the new needle is going to effect the mixture. It has a whole new taper so I'm really not sure if it will effect what main I need.
Hey BRIGHT YELLOW Z, I'm looking at getting the same components as you (just the Yosh slip-on and K&N setup), though. How well did it improve your low-end and mid-range? What jet sizes did you use?
