You'll find a simple video here that shows how to replace the clutch. Key points to look for are notches worn into the clutch basket fingers and in to inner hub.

Here's a good read http://www.dirthammersforum.com/clutch-maintenance-t98.html

Rastaman,
  Clutches are far easier than top ends.  Hardest thing is getting the side cover off and then it just get easier.  I have never soaked my plates before install although it does sound like a good idea. The only things to remember are to TORQUE the clutch spring bolts to their exact setting and use blue locktite on them.  They use a low torque and are easy to break. Cam.

We have always found factory kawasaki clutch fiber plates to be the best and last the longest. If its still the factory clutch the metal plates will be aluminum, steel replacements will last longer but wiegh a bit more.CBX

I haven't heard of soaking them for 24 hrs , but I do let them soak for a minute or two so they arent dry when you install them.  As CBX stated, Factory Kawasaki clutches seem to hold the best so thats what I'd run in all of my KX's.
And listen to Cam, you dont have to crank the H*LL out of the clutch spring bolts.  Torque them and it will save a lot of headaches later.

I think soaking them is good. I'm running the factory brand kevlar clutches with good luck but I wish I would have stuck with the aluminum plates over the steel. I would rather replace clutch plates then clutch hubs  :|.

 Aluminum clutch plates were invented to reduce motor weight and not for longevity although I am always suprised at how much abuse the aluminum plates can take.  I just don't like the particles they polute the trans oil with.  No mater how often you change oil, over time it trashes the tiny waterpump shaft bearings.  I used a DP clutch kit, steel with carbon fiber plates.  Was good.  The stock plates are good items and lasted forever.  Cam.

changing the clutch was easy saved my self bout $100 doing it myself i took the whole clutch cover off becuase it was welded and im putting a new one on and discovered the gaskets were all busted up so now im jus waiting for the dealership to call me n test the clutch out. if your wondering what type of clutch i got it is a sumo clutch kit. it was cheap later on ill get a dp clutch kit!! working on a budget here but im not too cheap when it comes to my bike. i could have went to the auto store and bout gasket paper for bout $5 but i rather spend  $26 to make it look good!! added 2 pics
