I was looking at an interesting thread on another site where people had made liquid cooled heads. I want to see if this could be taken a step further with a fully closed system that also incorporates the stock fins. These heads used an open flow system. I'm thinking, instead of all that, why not drill several holes in the cooling fins of the jug and head to accommodate copper tubing, with a radiator and a high flow pump and reservoir? If someone could come up with a visual representation on how this might or might not work, it would be very much appreciated. This is simply to keep the engine cool at high rpms and low speeds, primarily for jackshafted bikes frequently climbing hills or standing still on a hot sunny day at a damn long traffic light (hate those things, but they're a necessary evil).
