If you are having trouble getting the clutch cover off make sure you have removed all the screws(6) and try to activate the clutch,by this I mean turn the clutch shaft in the direction that it normally travels when you pull the clutch lever on the handlebar,it should pop the cover loose as you pull the lever,tap the cover with a plastic mallet as you do this .There are locating dowels around the cover and sometimes these rust and hang up the cover or the gasket might be holding it tight.
