check your cam timing maybe
here's a video to help
I have a 110cc stock 4 speed chinese motor. and i can tell you i beat the hell out of it
Started giving me problems after a couple years, so i junked it.
If your looking for a replacement go for a GPX motor. Tons of big bore kits, race heads, oversized valves, etc. They fit onto crf50 engine mounts.
