Are you talking about the air injection system? If so, and unless you have a good reason not to, I'd just remove the whole thing. I removed the one from my brand new '02 Vulcan 750, back in '02, along with the complete evap emissions crap thing. All that stuff must have weighed about 20 pounds, and had 100 feet of hose in it. Neither of these things serve any purpose, and the bike will actually run better without them, plus you will have a much cleaner, less cluttered bike. Jerry.
I am a motorcyclist, NOT a biker.
