Throttle sticking

[jriley43]

Last weekend I went riding with a few friends of mine. Anytime I went through a whoop section or hit a rocky section at mid throttle or higher my throttle would get stuck open. Each time it did it I would pull the clutch in and romp on the throttle, which would free up my throttle. I have taken my carb. out to see if maybe the slide was sticking on something, but have not found anything that would cause it to get stuck. Also checked the throttle cable, and it was working properly. (I went ahead and oiled the cable) Is there something else that I am missing that would give me this problem.
