Default 4 stroking

My motor is 4-stroking at the bottom end, but it runs pretty well at mid-full throttle. I have a stock NT carb on with the stock jet, I live at 5,000ft. My needle clip is at the top notch. Any suggestions? Smaller jet? Should I leave it like it is until I'm done breaking the motor in, and then go smaller jet?
