Well you are going to need to pull the carbs and clean them out. Even with no fuel in the tank I am sure the carbs are going to be nasty from what little was left in them. I would drain the case oil and replace it then fire it up and hope to hell you clutch is not stuck together so bad you cant get it loose. If the stuck is stuck and will not release you may end up needing to pull the clutch over take the cover off the clutch and pull the plates apart. Other than ride fire it up and ride the hell out of it.
OOPS Carb not carbs
