Not that I know of , unless i need to re-read every service manual Hyosung has made carb 650’s , but you can quickly on Youtube & Look at how they balance carbs on the older Suzuki TL1000S & Honda VTR1000F, as some DIYer’s tend to get their hands stuck in (“sometimes” a little better than mechanics at the garage but… use caution).
These two bikes while bigger in CC both still use similar size twin carbs as the Hyosung does (around 35mm-50mm ish bores) , then you will get some carb balancing kits , run your bike until you find the sweet spot it likes.
If changing anything, always take pictures or write stuff down, this can help you go back to whatever the default settings were in the carb incase the bike runs worse.
