Yamaha XJ 900, Carburettor balance and adjustment drive check

I just balanced the carburettors and adjusted the idle mixture as I described in one of my earlier videos.
After each completed adjustment I like to confirm that I got it right, by start driving without using any throttle, to check that all 4 cylinders pull evenly - if they don't run evenly, the bike will stall when performing this little procedure.
Have fun keeping the old bikes alive 👍
