Once you have taken the flywheel nut off screw in the puller into the external threads till it bottoms then start screwing in the bolt that will press on the crankshaft till the flywheel comes off. penatrating oil would be a good idea so would putting the bike in high gear and holding the rear brake so the flywheel stays still (probably have an assistant do that)
With a special tool. It's called a flywheel puller.
you have to use a puller..... you can rent them or get them on eBay for about $40
use a wheel puller
you have to remove the flywheel with a flywheel puller or maybe knocking it off with small hammer blows.
Take the engine shroud of the top of the flywheel - take the flywheel nut off - Put a puller on it and pull the flywheel off remove the old pieces of key and replace with a new one, and reverse process putting it all back together.
vice versa

Not easy with out the correct tool (part # 19165) flywheel puller. It's only 7 or 8 bucks, but it can be done without one. Use a strap wrench or a friend with strong hands to hold the flywheel while removing the nut. Flywheel can then be pulled off. If seized onto crankshaft, DO NOT pry off with screwdriver or pry rod, you will damage the soft aluminum crankcase. Use penetrating oil and a slide puller or generic puller tool, but be warned that sudden impacts or jarring can break or knock the flywheel magnets loose! The process is probably similar to what is described in this article. http://hubpages.com/hub/removing-outboard-flywheel
