My 1999 fxdx dyna has a holley carburetor which the previous owner clobbered up one of those hyper cleaners and put on it. And when I say clobbered I mean it in the truest sense. Have any of you Harley people run across one of these carbs? I think they only used it that year. What I would like to find is the proper air cleaner for it. Or at least the backing plate.
