I am going to pull it apart and clean it out but it sounds (to me) like I need to make some adjustments. I played with the fuel mixture screw a bit but didn't solve anything.
(2002 KX65 with a trackside pipe)

Sounds like if it does better with the choke half closed, then it is running too lean. Havent taken my 65 carb apart yet, so cant answer exactly what, but every other carb for midrange has been a either a pilot jet or needle adjustment to change the midrange. I am sure one of these guys will post up that has taken one apart.....paging Teddy?
