The combination of slide cut-angle, needle taper, needle height, and needle jet make it possible to get the right mix at any throttle position. Butterfly carbs only control the butterfly opening as the throttle position changes. The mix is dependent on other factors that are harder to change and control. Yamaha used a hybrid Mikuni carb that had both butterflies and slides. There was a vacuum controlled diaphragm on top where the cable would normally enter to raise the slide, and then there was a butterfly at the narrow end of the horn. The butterfly position caused a given amount of vacuum that would raise the slide the right amount for the engine load and rpm. It made the old Yam 650 twins very nice to operate. I actually have a pair of these that I was always going to try to adapt to the 700. BobG
