Just get right in there, I have never done this before, but I just took my carbs apart last week and it's not that complicated, just go slow and keep everything seperate. take pictires! There are some small parts in there that will fall out so, be careful where you work. Have a clean bench!
a few tips
-note the settings of everything before you disassemble
-get things clean(plenty of threads on that here)
-the jet sizes are on the jets, so once you take them apart, you'll know what you got.
These are just a few hints from a newbie

I used a product called hurrisafe carb cleaner to clean the carb bodies. The link is www.hurrisafe.com/newpage4.htm
I chose this product because it is safe on all the rubber parts in the carb. Unlike berrymans which will eat your skin as well as the rubber in the carbs this stuff is biodegradeable and pretty mild. I diluted it 1:1 with water and placed the carbs in a bucket of the stuff. My carbs slides were stuck so I soaked them for a couple of days.
After soaking I was able to remove them. For cleaning the passages in the carb bodies and small metal parts I used the walmart brand carb cleaner. Then used compressed air to blow everything out. If you need to clean the small holes in the jets out a single wire from a brass or steel brush will work. I purchased k&l brand carb kits, some of the kits were missing a couple of parts (clips that hold the needles in place) so I reused some of the old carb parts after I cleaned them up. During reassemble I used a little grease on the rubber parts as well as a light coating in the carb slides and throttle shaft. Gaskets were assembled dry. It is important not to force any thing when putting the carbs back together, if something doesn't fit find out why. The hardest part of this job was putting the carbs
back on. Trying to get the airbox side carb boots on was
a real pain. If you plan on reusing the old boots I found it extremely helpful to soak them in top end cleaner or seafoam. Any product with naptha in it will bring the old boots back to life. They will soften and swell so you can install them. You can use a piece of hard plastic or a screwdriver with tape on the end to help get them into place. I had to walk away from the bike a couple times while putting them on..definitely an excercise in patience. Hope this helps.

Definitely get the manual bro! You'll have your jet size specs, detailed instructions on how to disassmle and reassemble, and learn a lot to boot.
One bit of advice probably not in the manual .. wear eye protection when shooting cleaner through those passageways .. you may shoot in one passage and have it come out in another that is pointed right at your face!! :blink:
Try not to mix your parts too .. keep the parts in sections according to the carbs. Take your time, watch how it all comes apart and you'll be fine.

One last thing. The throttle slide seems to be stuck. Should i be able to move it by hand? right now it only moves a tiny little bit then gets stuck.

And hold tight to the jet when spraying with compressed air:pinch:
