Cleaning dirt bike carburetors with Sea Foam [SOLVED] Asked by Patrick H. In Ontario How would I use Sea Foam to clean my dirt bike carbs?
Hi Patrick. A dirty carburetor has excessive varnish residue that restricts fuel passageways. Adding Sea Foam to fuel works to clean and reliquefy the sticky/heavy varnish back into the fuel and burn in the chambers. All you need to do is pour a high concentration of Sea Foam into the fuel and run the engine. If your dirt bike engine is running rough, add a whole can!
