How does it run at mid throttle on smooth ground? Could be the float level. Is the screw/plug in the top of the slide that holds the needle down, in? Are all the carb/airbox boots fitted correctly and tight?

Im the search nazi you were warned about.

I had the same problem with a new/used bike. Try
1. adjust your AP timing. Make sure its correct
2. Find out what your jetting is by:
a. cleaning out the carb

3. put in new plug
4. you may be too rich. To rich can cause a midrange miss.
