Also check the condition of the reed valves.and adjustment of the reed valve stopper.Make sure its sealed when you put it back together.usally gasket on one side and sealing compound on the other

if its flooding then the carb is in need of investigation,it will be either the float/float needle or seat/or float height set wrong.but these bike are prown to head gaskets leaking water and losing compression also due to the gasket leaking.a head skim is always recommended and also fitting a genuine gasket not a nasty pattern one.
