Super easy my friend. What kind of levers did you get?
1. Loosen off the clutch cable to give it some slack. I think I completely unscrewed that adjuster ring right out of the lever housing IIRC.
2. Disconnect the clutch cable from the lever. I believe the cable rotates towrds the front of the bike and then will drop out the bottom of the lever. Just look under at the bottom side of the lever and you will see the hole and 'notch' for the cable to slip out from.
3. Unscrew the clutch lever pivot bolt nut (underside of the lever housing). You
do not need to remove the lever housing from the bar.

- I'm not 100% sure if it's the clutch of brake lever, but there is a metal bushing/sleeve in the stock lever that you need to pop out and re-use in your aftermarket levers. I'm pretty sure it's the brake lever.
4. Clean off the pivot bolt.
5. Re-lube pivot bolt and inside bushing area of your new levers with grease (not oil). I used some white lithium grease I had on hand.
6. Place new lever on and re assemble in reverse order.
7. Re-thread in the silver adjsuter ring back into the clutch housing and adjust the cable slack and lever (if your levers have that option).
TEST RIDE!!!! More than likely you will have to do some "on-the-fly" tweaking and adjusting to get the lever and clutch cable slack reset to your liking. Don't just assume it will be the same and ride off to work or something!
Here is a pic of my PAZZO shorty clutch lever installed:
