Motorcycle gas gone bad – can Sea Foam help? [SOLVED]
I have a motorcycle (2013 Ducati Monster 1100evo) that sat for 2 years. It has about and one inch of fuel in the tank (less than 1/8th of a tank). I opened the gas cap and could tell the bit of fuel in the tank is bad. Because of that I don’t want to start the bike. I plan on extracting the bit of fuel out but fear that there will still be some ‘gum/varnish’ left at the bottom of the tank (near the pump/filter). I wanted to dump about one gallon in there with some Sea Foam swish it around and then extract that out (just to ‘backwash’ the tank). After that fill tank with premium gas and Sea Foam. My question is how much Sea Foam should I use for the ‘backwash’ process?
Or, I’m open to other suggestions on how to get the bike’s tank safely clean for new gas and as to not to damage my fuel system after 2 years of no start.
That’s a great description, Sanjeev. What I’d do: Add one can of Sea Foam and one gallon of fresh gas to the tank. The new gas and Sea Foam will disperse evenly with the old gas. The new gas will bring enough fresh ignition volatility, and Sea Foam will liquefy the old varnish. Run and operate the engine until most of the fuel is used, then add another can of Sea Foam and a gallon or two of fresh gas. It may run rough at first but will progressively clean and improve as you go!
