There's a really cool tool out there that can help you get your carbs dialed in. This is the Color Tune (Amazon link, or do a search for "color tune" or "Gunson Color Tune."). Check You Tube too. There are a lot of videos on this. For example: https://youtu.be/bRfSj47QCio.
It's a spark plug with a transparent window around the electrode. It lets you see the color of the flame in the combustion chamber. You install it like a regular spark plug, run the bike at idle, and adjust the fuel mix to get the right (blue) color flame.
So, this is good for adjusting the fuel mix, if that's what you're after. It won't tell you about carb balance, but for old bikes you get an assistant, have them feel the slides move as you twist the throttle. If they seem like they're moving in tandem, then you're good. Adjust as needed if one starts to slide up before the other. For idle, I do it by ear. You'll also want to check timing with a timing light too. Remember, a carb is part of a system. It's not just the fuel mix.
I've used the Color Tune it on my old '71 BMW that has simple slide carbs (Mikuni) and no vacuum ports.

Personally I recommend one of these for setting the idle mixture:

Make sure to get the right size for your bike if you decide to go that route.
