A couple of years ago when I went to the Boo Rally in Jefferson Texas there was a guy that had a VTX 1800 with dual intake on it. It was very cool looking.Will tell ya it sucked the air!! Only problem that I saw was that with me being long legged the intake on the other side would be kinda close to my leg. Also it won't work for the newer VTX 1800s because the reserve for the radiator is on the side of the engine.
