If you used Sta-Bil or a comparable fuel stabilizer as outlined in our storage tips, your fuel should be in good shape as long as it's been a year or less. Regardless, double check by opening the filler cap and looking inside for gunk or stratification.
If the fuel is consistent and clean, you can go to the next step. If not, you're better off draining the tank, fuel lines, and carburetor (if applicable) before running the engine. If you didn't spray fogging oil or lubricate the top of the cylinder before storage, you may want to remove the spark plugs and pour two tablespoons of oil into the spark plug ports; this will lubricate the top portion of the cylinder walls before you start up the bike.
