I'm sorry that you have had such bad luck and trouble with your bike however there are many of us who have accrued thousands of miles from a Chinese 2 stroke engine.
Maybe it's time you examine how the engine is installed, maintained and ridden before making a blanket observation based solely on your single experience.
I ride my bikes daily and I trust them to get me to where I want to go and home again and never consider that they'll leave me stranded, or walking. They haven't yet.
Just my experience, but one shared by a good many builders here.
