Go slow and take your time, there are plenty of tutorials on here how to clean your carbs.
Its actually quite easy even for beginners, turn your fuel switch off, start the bike to run the fuel out of the lines, take the seat off, take the plastic part off under the seat, disconnect all wires. remove gas tank, remove air cleaner and all accompanying parts, remove carbs and find a work bench. Once your on the bench remove the 4 screws that hold each carb together (be careful not to strip these, find the right screw driver that fits properly) and just clean everything with a combination of carb cleaner, and compressed air. take the jets out and hold them up to the light, you will be able to see if there is any grime or dirt in there. If so you can use a sewing needle, or other device to scrape the dirt out while also utilizing compressed air and carb cleaner.
wash, rinse, repeat.
