Remove the tank and carb, drain the oil again, and turn the bike upside down with the plug out. Use your hand and crank the the engine over repeatedly. Take the flywheel cover off and spay with contact cleaner. Clean and re-oil your air filter. Put it all back together and fill with fluids. Change your oil after you have run the bike some. Inspect and repeat as necessary on the oil change. I would run a 32:1 oil ration for a couple of tanks. The extra oil will be good for the bottom end. If you are already using a 32:1 mix, just continue. If you get it out early, you'll be OK.
