CVs or Flatslides?
I will try not to get too technical on this… When you open the throttle with CV carbs, they “compare” the throttle opening with the amount of revs (or vacuum created by them) to determine the perfect match that gives the best mixture. This means you can crack the throttle open at any given revs and the bike will accelerate cleanly, without hesitation. But the CV carbs always have this valve stuck in their throats, even when fully opened thus hampering the flow, which is where flatslides come in. Flatslides only have a big slide that opens as fast as you can jank open the throttle, but if you are at low revs this will bog the engine, so you have to carefully “feed” them yourself.
