I'll run Seafoam a couple times a year as a cleaner, but prefer to use StaBil for the winter. I'm running stabil now, after each ride, I stop and top off the gas and add appropriate amount of StaBil. I like to keep my tank topped off for rust prevention. My previous bike (83 Venture) this worked for years. I do plug in charger once a month to top off. It is parked in an attached garage that never hard freezes, but can dip to 30.
