First, do you have a manual? Here's link:
Second, follow link and watch videos.
Third, google Vstar 1100 Carb rebuild. Everyone has a different way of doing it but watch a few to get the steps memorized.
Forth, Follow this link and read carefully and all links is suggests. It starts out talking about syncing carbs that you must do after rebuild.
Fifth, you have a phone with camera? Take a picture of every screw you take out before you remove. Video would be better.
Sixth, bag and tag every part. It's easy to forget where they go.
Seventh, work on old white towel, there are many small parts that are easy to loose and the white towel makes it easier.
Eighth, you will take both carbs off together but only rebuild one at a time.
Ninth, I use brake cleaner not carb cleaner, just spray each part, used old toothbrush to clean parts. DO NOT use any strong cleaner on ANY rubber parts, Just soap and water.
Tenth, don't buy carb kit. You only need the two base gaskets 9 out of 10 times. If you need anything else I can advise where to get them. Local dealer will have gaskets but these work well and have the oring you might need. Link to gaskets, you need 2:
Eleventh, don't mess with float arm. The float needle might be dirty and you can get to it without messing with float arm. It can be challenging to get float set right if you bend them so be careful.
Twelve, be patient, don't hurry. This is not a difficult task, but can be a little tedious. There have been many here that have had to redo carbs several time for not completely cleaning everything really good. Especially the pilot jets, they have small holes in the side that must be clean. The wire from a bread tie works great for this.
Thirteenth, you must sync carbs after you get them back on. This is a must. You can bench sync and will close enough for most people. Sync info in number 4 above.
I've only given you the basic info. At any point you have questions, ask. I check the forum daily and will respond first chance I get. It's sometimes difficult to explain the issue, so pictures help a lot. I've done hundreds of Carb rebuild. On the 1100, from start to finish it's about an hour for me and that's spending time cleaning the engine between the cylinders that you normally can't get to. But for the first time set aside two days, you might get frustrated and need a break. It's not a race, you just want it to be right. Now, let your questions begin.
