It should be pretty simple. Just don't do what you don't need to do. 1st off--have you ever rebuilt a carb before? If so, then it's probably very similar. So here's what you're gonna do:
1st- Rule. Do one carb at a time (especially for noobs)
2nd- rule. Get either compressed air in a can or an air compressor with a blow line.
Your carbs probably only need cleaned and maybe some new floats, needles and seats. (in that order)
**Now, I must note that this is all just my personal opinion which I have gained from my own personal tinkering**
Can you do me a favor and list how many miles your bike has, and what year the bike is and post a close-up picture of your carbs?
