I agree with Mr. Paul on both counts. I use a smart charger to keep the battery in good shape. And in 1 month, ethanol fuel can degrade and cause problems. I add stabilizer in the recommended ratio, go for a spin, turn my fuel valve to the "off" position and let the bike idle until it stops running (no more fuel in the carb bowl). On a bike without a conventional petcock (no "off" position) about all you can do is ride the bike until you are confident that the stabilized fuel has circulated throughout the fuel system.
