The break-in oil will have all the sharp edges and dust/sludge that gets knocked off the inside of the engine. You've GOT to change that on Chinese stuff. Change or clean the oil filter too. It's not well-made enough to skip that. But that's not what's causing your lack of power.
Valve clearances would be the next thing I'd do, I think.
