Nope. Instead, the pilot jets provide the additional fuel needed for on-throttle transitions.

The acc pump is a function of a carb, not necessarily any particular kind or vintage of atv. Keihin FCR carbs, which are fitted to many sport atvs these days, do have such a pump.

The Raptor carbs are vacuum operated, this is why they do not need an accelerator pump...........

You may see throttle plates in the carb, but the main air restrictor is the guillitine valve, it controls the fuel delivery and air...........
