Hello. Hope this is ok to ansver in english here.
As you see on myrons moped page cylinder on V1 engine is with quite small ports, changing only a carburetor without any other modifications wont give you much. In 2-stroke engine carburetor, cylinder porting and exhaust pipe is some how balanced combination.
Because tuning power out of 2-stoke engine is other hand quite easy byt if go on details its quite complex proses. First you should educate your self litle bit theory how 2-stroke engine works, specially how 2-stoke exhaust works and what is purpose of expansion chamber in 2-stroke exhaust pipe. Tuning a 2-stroke engine is all about cylinder ports and exhaust pipe.
Depending on what possibilities you had it might be good starting point to mound new litle bit bigger carburetor to your moped. Changing a carburetor might sound easy job but it might be not easy at all!
There is tons of things what can go wrong or wont fit properly. First problem might be intake manifold size, how to fit different carburetor if intake manifold outside diameter is different? Scond common issue is throtle cable how you fit or modify your throttle cable to a new carburetor? How is airfilter connected? When you got those things solved you need tune your carburetor by changing a main jet if engine is too lean or rich. In two stroke engine its essential to NOT run engine in lean condition. If 2-stroke engine runs too lean it quite easily causes major malfunction like piston meltdown.
If you deside to change a carburetor DONT by a bigger SHA because its not good carburetor to start training because its lack of features and can be tricky to get working properly.
