1. Uhh... another language issue? I'll go out on a limb here and say that your bike doesn't have a governor.
2. If you tried to jet the stock carb and weren't happy with the results, the next step was NOT to replace the carb with a larger one.... the next step was to find-out why the re-jetted stock carb was not running well. Most likely, you needed to research jetting some more to come come-up with a better / correct combination.
3. I can only guess that "hard breathing" means you hear it bogging when you twist it wide open?
4. You said you just "restore the engine". I'll guess again; does that mean you did a new top-end? If that's so, why would it have low compression? Did the bike run poorly before the "restore" or only after ? If the compression loss happened after a new top-end, you need to start looking there. Have you actually checked the compression or are you just guessing?
