2010 KX250F - Engine lags when truning throttle fast

I have a KX250F 2010. When I turn the throttle fast, the engine lags before it accelerates. Is there something that I can adjust in the carburetor to remove this lag and allow for a quicker response when you turn the throttle fast?

Thanks

Do you have any kind of aftermarket exhaust system on it or is it bone stock

Lift up your subframe

Look into the carb bell

Whack the throttle and look for a 'stream' of gas 'squirt' shooting into the engine (motor off)

That's the accelerator pump.
