OK so I've decided to spend my much needed holiday giving my bike some winter love as its been stuttering and misfiring a bit recently

my Carb slides were a bit rough so I've sorted that and given them a clean, valve clearances are all OK, as I did them not too long ago but checked them anyway. Sticking a new exhaust on swell so decided to balance the carbs, hoping this will help stop it running so rich.
So Lon story short any advice on Carb balancing? Never don before and could use some tried and tested tips.
Cheers F
Oh also re-gapped sparks and have new air filter
