First, the oil needs to be drained from the e50 motor. I've already made an Instructable on how to do that. If you need help with that part, go here...https://www.instructables.com/id/MOPED-OIL-CHANGE/
fter the oil is drained, let's loosen the clutch cable. There is typically an adjuster that can be loosened. Should be a 10mm nut that can be unscrewed to do that.
After that, remove the centerstand spring. Put on your safety goggles, or you could put out an eyeball. Seriously. I used a spring removal tool that I made from an aluminium bar and a brake cable.
Once that is done, you can loosen the (4) screws that hold on the clutch cover. It could possibly be a J.I.S. head screw, which is like a Phillips head, but really big. I used an impact screwdriver. Sometimes they are tight. Make them loose 1 by 1, then remove them.
Once the (4) screws are removed, you should be able to pry off the clutch cover. It should come off easily.
