SoCal Jetting favors

I would like to jet my bike and learn about all the qwirks that come along with the Carb. I'm very mechanically inclined and wouldn't think twice about rebuilding the motor myself but when it comes to the carb I'm scared to touch it. Would anyone be willing to do a hands on tutorial of jetting this and showing me what changes do what? I'd be willing to meet you at a local track, riding spot, or the desert to do this. Give me a list of parts to buy and bring, jets, needles, etc... I hear about all these wonderful things but don't want to pull it apart only to never have it run right again.



"What's that?"

"It's a Yellow 99' YZ400!!"
