If your clutch is shot there are a few things to check.
1. Look for grooves on the clutch basket where the clutch plate tabs slide in and out, if there are deep grooves then the plates don't move and you get a grabby clutch.
2. The tabs on the clutch plates shouldn't be too deformed, if they are you get a lot of slap back and forth.
3. The thickness of your clutch plates should be in spec, not sure what that is but check with Barnett Clutch's to find out.
I have pictures on ADV rider somewhere of my original clutch basket that was badly worn, if you can find that you'll see a great example of a worn out clutch assembly.
