Grimes hit the nail on the head. Stabil in the proper amount and you will never have to worry. Is the tank full? If not I would fill it up with new gas and add a $5 bottle of Chevron Techron Fuel System cleaner just to be safe.

I forgot to put gas stable in mine last year and I fired it up the other day. It started like it has been sitting for a day a not 6+ months. It's been running real good and the A/F ratio is still perfect & smooth but I'll probrably run some fuel system cleaner through it anyway once all the old gas is gone.

I worked at a motorcycle dealership for 10 years in a previous life LOL but what was funny was that on a lot of bikes after 6-7 months the gas would turn green in color/tint and smell just like terpentine, it seems to be worse with bikes than cars.

Just drive it gently for a while, since that fuel will have lost quite a few octane points. My suggestion would be to drive it on the highway to burn off a lot of the fuel quickly. Keep topping it up with fresh fuel every 100 miles, and by the time you've put about 300 miles on it you should have a much stronger mix of fuel in there and then you're good to go.
