Could this passive cooling idea be adapted to our engines?

    This is a welding video, but it got me thinking. If copper were attached to the cooling fins of a bike motor, would it help keep the motor cooler? It seems to make a substantial difference in keeping the sheet metal cool enough to be welded without damage.

    The weldor is right about using copper, what he failed to mention is that electric weld doesn't stick to copper . Using a bucking bar
    [ same word , different use ] of copper, allows the weld metal to flow across the gap, resulting in a strong repair.

    You could try wrapping some 3/8 copper tubing around your exhaust, and cylinder fins, but I'm unsure if it would do any good.

    I was wondering if a copper head gasket that's made large enough to extend as far as the cooling fins might be a good idea. That way it's part of the motor, can be made to look good, and pulls heat directly from the hottest part of the motor.
