Carb performance gains?

Well i just got my leovinci exhaust on. it says its meant to fit a peugeot 103/104 sp, spx, and a couple other peugeot models, but of course, it had a completely different interface to the exhaust port. I was able to cut part of the interface tubes from the old and the new exhausts and the old exhaust's pipe happened to fit nicely in the new one's. So i then had my dad weld it for me.. anyway..its on and everything and performance is noticeably increased. The accelleration now is tolerable, though still not great.

My question is: I've heard alot mentioned about how larger carburetors are better for high rpms and smaller carbs for mid to low rpms. Right now i have a 12mm gurtner carb (stock) installed. If i were to move up to a 15mm or a 17mm(or would that be too big?) i should get more high end power, but would it noticeably decrease my low end accelleration? if so, could i even it out a bit maybe by getting a rear sprocket with a couple more teeth? now that i have some accelleration, i'd like to start trying for a higher top speed (30-35mph currently), i just dont want to get a higher top and screw it up so that my accelleration sucks again..
