Recommend new carburetor

[Yotgguitar]

I have a Baja warrior 200....
I recently purchased the bike and it already has a TAV, EXHAUST AND AIR FILTER UPGRADES..
I can get the bike up to 45 mph, so the previous owner obviously did something right...
My question is I want to upgrade the carb... It leaks gas from the bowl and the bike slightly sputters when applying throttle...

I tried cleaning the jet and emulsion tube ( they were already very clean) but it still sputters...
I'm thinking an upgraded carb would be best...
What would you guys recommend for a mildly modified engine?
I need something easy to replace it with... But i would like a carb with adjustments that could "grow" with me if i decide to upgrade anything else...
Is there such a thing?
I've seen the 22mm-26mm carbs, but i don't know enough about it to buy one... I would rather ask questions twice and buy once...

-Thanks, Matt

Get a 22mm round slide kit. I have a .650 carb on my bike and it makes better top end but lost some throttle response and low speed power. Part of it is my combination of other parts too but some of it is the .650 carb. Get a completer kit. I think I paid $100 for my 22mm kit.
