Could have something broke inside. Even with a bad clutch you would feel drag with clutch out and in gear I would think. On the right side case, take that little 2 screw cover off, that's where your clutch cable hooks to a barrel and open and closes the clutches see if anything is wrong. If your shifter barrel or something is broke inside it may not be shifting in to gear at all. When you pull the clutch handle in does it fill stiff like you have a clutch??
