I've heard that it improves the 700s more than the 600s. I haven't tried it but I do know that in drags alot of the improved stockers run them. I think all it does is equalized the pressure in the two carbs. Alot of guys just make them.
The ones that I have seen were made out of aluminum. But I would guess that any thing you make a small chamber with two pipes going down into the carbs would work. I don't think that the volume of the chamber matters.
just a word of caution the reason most bottles are plastic is because of there light weight, many people have had burn downs because off cracked carb boots where the bottle mounts due to vibration. just to add the general opinion is they do nothing for mikuni carbs,just older kiehins
