Replaced my spark plugs and the old ones indicate that my bike's running rich

I don't know much about diagnosing the exact source of the rich mixture. I cleaned the carbs and I reallllly would rather not take it out again to adjust the jetting. I came across a post saying that removing the air snorkel is very easy and it will bring the mixture to a leaner side. Do you think it will help in my case as well? Seems to me that the snorkel can be re-inserted if it ends up screwing with my bike, so I'm tempted to give it a try.

Other than seeing that my spark plugs are black, I don't really know how to tell that it's running rich. It runs fine for the most part and I haven't had any issues that I couldn't fix, so far.
