On the street the Kitaco 88cc Ultrahead runs best with a Keihin PE24 carb, as the 20mm Keihin will give more low end power, but is too small overall for the application.
that ultra head you got, you will really be pleased when you get the touring cam in. the touring cam works good for the moto cross application. go try the touring cam and let us know as we will probably be able to see your smile through your writings.
