Hey Frank, I found some great information about carb's over on another site I belong to.
It's an artical that really open up my eyes to how my Keihin works. I know not everyone is running that carb, but the thread really helped me.

BRed and his posts are gold.
Well thought out, great insight to mechanical issues and his write ups, have saved me hundreds of dollars. Heck, my scooter runs like a different machine with just following his threads.
I hope it helps you understand these carb's a bit anyway.
