2011 Kingring 50cc JL40QT-4 RPM troubles

Well that is good that you adjusted the valves but if it is still not getting over 4K only a few things will cause that.
1. Low Compression
2. Something wrong with the Variator
3. Bad CDI

And that is if when you do reach 4K the motor is not backfiring or sputtering or bogging or making sounds.

Let me ask when you crank it up full throttle does the motor make any sounds, BRAT, POP, BACKFIRES?
Or does it just wind up to 4k and runs good at 4K?
