    Fuel Treatment to clean valves

    Has anybody ever used stuff like this in a bike to try and clean the crud off your valves, like the can says it will?

    Not me.

    Have you looked at your valves to see if they are crudded up? You can't really see much by pulling the spark plug.

    In my opinion (which could easily be wrong ), the only place that a build-up of crud would affect operation is on the seating surface of the valve and head. I just can't picture how a fuel additive is going to keep anything out of there.

          i'm trying to clean my values on a kawasaki without dismantling the valves from the head. I have the head off right now. I've tried a little seafoam then B-12 but haven't really scrubed yet. Made very little of a difference on the exposed valve surface. Worked better on/around the combustion chambers. I know the best way to clean is a tear down but i do not plan on doing this, yet. Very cheap bike and trying to keep it that way.

          I have 2 heads to work from. On one head the valves are not that bad but on/near the mating surface with the valve cover gasket in one chamber the surface is gouged up. All other chambers look descent.

          The exhaust ports/valve shafts look better on one head compared to the original head although they are not great.

          The original head that came off the bike the valves are pretty carboned up.

          I'm trying to figure out which head to use.

          I'm getting a camera either tonight or tomorrow and will post pictures asap of both head valves.

            The surface of the valves doesn't really matter. It's the ring that sits on the seats that does.
