I had to pull mine apart a couple times last season, so I became pretty familiar with the drill.
Unfortunately, you have to remove the whole side cover to get to it, as there is no clutch cover.
The first step would be to drain the coolant and oil. If you're clutch is smoked, I would run the bike and drain the oil. Then fill it up again and repeat. This will help flush out the aluminum particles from your old clutch. I don't know if others do the same, but I don't like the idea of having silver aluminum sludge between my new clutch plates.
Anyway, you'll also need to remove the kickstart lever, foot peg, and water pump hose. The water pump cover can stay on, as the whole water pump assy will come off with the outer engine cover.
The plastic powervalve cover also comes off to.
Next, remove the bolts that hold the cover on, and lift off the cover. It might be snug, but resist the urge to pry. Maybe try tapping it with a piece of wood to break the gasket seal. One mine, the most resistance was around the kickstart shaft seal.
The powervalve lever will come apart as you wiggle the cover off the side of the engine.
After you remove the screws in the pressure plate, the plates and disks can be pulled out.
