I'll show you how to do it.
I made it at Techshop. The have a work bay where you can work on your car, motorcycle, moped... whatever! There are 3 of them around the SF Bay Area, so it's pretty convenient. There's others around the country and they have lots of tools and workshops. Wood, Metal, Fabrics, Electronics and more. It's rad.

A flathead screwdriver
A piston stop
A socket wrench with a 17mm socket and a sparkplug socket
Step 1: Getting started
Step 2: Clutch cover removal
Step 3: Unscrew the, uh... thing.
Once it's loose, slowly pull it out and grab the spring and that is below the clutch arm. Don't let the spring fall into the motor. Continue removing the bolt and grab the spacer that is above the clutch arm. Don't let the spacer fall into the motor either.
Move the clutch arm gently off to the side. don't let the clutch cable fall out of it's slot.
Now remove the cap from the center of the clutch.
