Testing the inlet manifold is easy too shoot loads of WD40 at it while bike is running, if the idle speed changes there is an issue. Any of those or dirt blocking the carb can just happen..... if it sat for ages could be old sediment and **** in the tank and just bad luck it shifted and caused a blockage when you stopped.
