Can you fill motorcycle carburetors with straight Sea Foam for winter storage?

Good question, Paul. It’s not necessary to use straight Sea Foam. Using a high concentration of Sea Foam in fuel will work to protect the engine and prevent gum and varnish from forming in a carb. Here’s a good storage routine for motorcycles:

Stabilize fuel

• Add at least 1 ounce of Sea Foam for each gallon of tank fuel. Even better, add a greater concentration of Sea Foam to a low tank of fuel (8 oz of Sea Foam per gallon is just fine!).
• Run the engine long enough for the treatment to work through the entire fuel system.

If you’d like, you can also fog the intake and lubricate cylinders before storage.

Fog/Lubricate Gasoline Intakes
With the engine running, insert Sea Foam Spray straw (cut if needed) into intake throat
(carburetor) or directly before throttle plate opening (fuel injection). Spray a series of
3 to 5 bursts, then a final direct stream while shutting off engine.

Lubricate Cylinders
After fogging the intake, allow engine to cool and remove spark plugs. Insert Deep Creep straw to
spray each cylinder cavity. Before re-inserting spark plugs, crank engine to rotate pistons. Note:
Deep Creep and Sea Foam Spray are interchangeable for chamber lubrication.
