Because of all the endorsements of SeaFoam in this thread I went out and bought two cans of the stuff (at AutoZone - $6.99/can). Poured the first can in with about 8 gallons of fuel. Tank is at about 3/4 full. When should I put in the next can?
Another vote for Seafoam here. I put it in the gas tank every few thousand miles because I occasionally have to purchase "generic gas" when traveling in the middle of nowhere. It solves a fuel level indicator problem quickly. I sucked it into the engine once but did not get the massive smoke cloud so many people talk about. I have a hard time believing that my engine was just too clean at 85K miles.

You should run the tank down and repeat the next fillup. Then do it periodically (every few months).
Dumped in a can of Techron when I first bought my car 4 months ago. With all the rave reviews of Sea Foam, went out and bought a can at Pep Boys yesterday and dumped it in the car AND the Harley. Sounds like good stuff.
