xr 400 pumper carb

Anyone ever cross this bridge?

I currently own a 01 xr 400 and need some help selecting a pumper carb. I'm trying to eliminate the flat spot at the bottom during rapid low rpm chops of the throttle. what's available? and where? thanks!

Looks like I got my answer indirectly. thanks!
