if its like older kawis then you remove the bolts or screws from the black plastic ( flame arrestor) on top of carbs.
then inside, there should be 2 bolts per carb, with locking tabs.
bend those tabs out of the way, so that you can unscrew them ( 10mm socket I think) , once the choke and throttle cables and fuel lines are removed, the carbs should lift off.
stuff rags in there so you dont drop anything down in the intake!
