Be very careful when you have the carbs out. There are SEVERAL small parts that are absolutely crucial and have extremely tight tolerances. My advice to you is to have a VERY clean, well lit and organized workspace. I bought a few of the Plano 3700 series plastic storage boxes and labeled each one with the parts going into it. This makes it much easier to keep track of everything and you can simply close the lid and lock it if you need to walk away without the fear of losing anything. You can label each box 1, 2, 3 and 4 this way you know what parts went into what carb. (I am kind of obsessive compulsive about things like that)
Also, take your time on each part. Do replace the rubber components. I had planned to replace all of the internal components with new parts purchased online, but Two-Tired explained to me that there was nothing wrong with the factory parts...they just needed some attention...and right he was! Be meticulous about the details. Get the right tools to clean the carbs with. (solvents, brushes, picks, emory cloth etc.) TAKE YOUR TIME! I cannot stress this enough. The brass is soft and the tiny holes in the emulsion tubes need careful hands...but you CAN do it! I had ZERO experience with this, but still managed to do an entire rebuild in my garage on all four carbs. It was a great experience and highly rewarding when all was said and done. Trust me on this, cleaning and rebuilding the carbs was probable the single most productive thing mechanically that I did to my bike after I took it apart. Made a HUGE difference especially after I performed a proper sync.
You will find no shortage of great people here that are more than willing to help you and will go above and beyond (even out of their way) to help you.
