[Kurtoxic]

Im having issues with what I believe to be my clutch on a 2006 crf250r. The clutch is dragging heavily when the bike is in gear and the clutch is pulled in. The bike also clunks hard into first gear from neutral when it is running. I am not sure what is causing it, or if it is normal. I have fully adjusted the clutch cable with no success. I have also inspected the clutch basket for notches and I didn't see anything. I have also changed the transmission oil multiple times with no success. The clutch plates are close to their minimum specified thickness. Could this be causing my problems?
