Couple of questions about the JR50.

I'm replacing the clutch plates for this little bike and I'm not quite confident on what needs to be taken apart to get this done. Example:

I took the cover plate off the side of the case where the kick start attaches to the clutch. Seems to be a little tight to slide the old clutch out and put a new clutch in. Do I have to take the whole side of the case off? If I need to remove the side of the case is there any hints or tricks I need to watch out for? Easy way of doing it?

Aloha.
