You are on the right track with possible causes. I can't give help on specifics because its Chinese and I'm behind a computer. If it were a Japanese bike it would be a lot easier for me to help you remotely.
My suggestion is get it running decent and SELL IT BEFORE IT BLOWS UP. It sounds like it is on borrowed time based on the way you are riding it.
I got it fixed only cost me 40 bucks
