Has anyone attempted to and/or been successful cleaning a Yamaha Fuel Management sensor? One of the sensor is not working and before I have to buy a new one I was not sure how serviceable they are. Where it is broke anyways there isn't much to loose but curious to others experiences.

Also I saw somewhere that where was a recall on the 3 screw units some time ago for leak hazards? I believe these are the 3 screw units and didn't know if a recall or might apply to them anyways.

Thanks

Andrew
