Do yourself a favor.....don't add seafoam to the fuel, and let it sit in the carbs over winter......Bubba Steve and I both concur that we have seen more problems with rubber float needles on bikes that have sat for extended periods with Seafoam, and/or Berrymans B12 cocktails.
Those treatments are designed to be added, and run thru the system, and completely use the fuel up, while "cleaning" deposits. Neither is a long term storage chemical.
Add Stabil, I'll even go as far as say to use the new Marine Grade Stabil, it's bluish color, and works better with the ethanol fuel we have.
