Id make returning the carb your #1 priority. So pretty much everyone agrees that the 22mm carb is the way to go on the gx200/predator 212. If you are doing an open build (you know the ones where you have a race kart that ONLY runs at 5-9k rpm, then the 27/28mm carbs would be good for ONLY high rpms, usually in conjunction with a race head with oversize valves and other supporting modifications. These engines will make power only in the upper mid and high range, which is good for racing at relatively constant mid/high rpms, but mini bikes are different.
Think of it this way. You want a strong vacuum signal to get optimum mixing of gas at the venturi. You basically destroy that by going too big. If you stick with that carb, you will have a crappy experience during 90% of the time you ride the bike (which is starting, stopping, and going anywhere under 50 mph). Killing low end torque. Just my 2 cents. The max id go would be a 24mm flatslide.
