How often should I have to balance my carbs?

There isn't really a "schedule" for balancing, more how the bike is running. When carb sync is out of whack, you can have poor idle, poor off-idle response, “hanging” throttle and lazy return to idle. You can even suffer from fouled plugs if one or more throttle butterflies are opening early, thereby partially activating the carb’s progression circuitry.

You can find good instructions on how to balance them here.

On my bikes over the last 20 years,I find that I would "touch them up" when I did the full service.
Meaning once every other year or about every 20k miles.
The same time I change all the fluids,timing belts and plugs.
