Hi Sowiuk, just noticed your posting. I don't often come to the UK regional forum - seems to be a bit of a backwater.
I did a similar thing to yourself - stripped and cleaned the carbs. Then bought carb rebuild kits from NRP Carbs. Can't remember how many of the parts I changed.
Also, can't remember the jet sizes and so forth off the top of me head, best place to find the factory settings is a manual. If you don't have one, you will find free manuals on-line but I would always recommend having a hard copy to take in the garage.
Take a note of the jet sizes just for reference, might need a magnifying glass. Jet sizes for best running is affected by everything - air filters, exhaust, state of the engine, the cams, over-size rebore kit if fitted.
The biggest problem with the carbs on my XS turned out to be tiny splits in the rubber diaphragms. Didn't notice on first exploring the carbs but I started getting severe running issues - bike just would not take any throttle or rev past about 3,000. I though it must be an ignition problem but in fact it was those splits. You could see them if you held the slide up to the light and
gently stretched the diaphragm. Bought new slides & diaphragms from Heiden BUT they were wrong for my BS38s. Something to do with the way the needle is retained. Managed to buy good s/h on ebay.
The tale no doubt told on my build thread - look for Miss November. This link might take you to the relevant section of that long saga . .

If you search the forum there is a lot of information on carbs. Don't forget to look at the excellent guide in the Tech section:

And if you ask for advice, there are people very willing to help, for example, 5Twins has a great deal of experience setting up carbs on XS650s.
