Finally fixed my exhaust leak so a little more quiet but my carbs scream!
I have seen the expensive airbox for sale around $900 but has anyone found any other solution? I am thinking of using the Turbo Hats and running the input tube bellow the engine tin to a cone filter. Or are there any type of plastic molded airboxes out there that I can graft the weber bottom plate to? Running the open K&N filter housings. Ideas? |

Gary,
The CSP airbox I recently installed was $750 shipped. What a difference. I would think you could make something up similar for a lot less, but it will take some work. I do not know if you looked at my thread, but it really looks nice. |

Maybe the air filter housing off an injected car. |

two CB Performance turbo hats for the carbs.
One mid 70's VW beetle air filter box. Some 3 inch plastic tubing. Similar to the CSP box, you can make one that does the same thing. The turbo hats go on the carbs (duh) The tubing needs to be drilled into the side of the beetle airbox, then clamped to the turbo hats. What you gain is noise reduction, and if you look around, this has been done before. I have no clue where the links are...but I did find it years ago when I had sticker shock regarding the CSP airbox solution. rich |

I love the way my carbs sound. But then again, I drive with these. (IMG:style_emoticons/default/biggrin.gif)

912 air boxes would be the easiest to find (I would think)
Those units from BAS and CSP are great looking! |

Put two layers of a light weight Dynamat like product behind the back pad to reduce noise but my carbs aren't screamers, it's just induction noise.

Ideas? Somewhere I saw someone using Honda Goldwing? (maybe) air filters to cut the induction noise....maybe 3 years ago or so...... Bingo! I had this in the back of my head too just couldn't recall through the fog. I just purchased a pair off ebay for less than $30 shipped so this will be the project. http://www.914world.com/bbs2/index.php?showtopic=194570 |

As I have done some research overnight it seems that the breather boxes from the 1984-1987 Honda Goldwing 1200 are the ones.
My original thought was to have these type of boxes fed by a common cold air tube but I like how this setup is, nice and clean. I think these molded boxes will do more noise reduction than metal ones like the turbo hats. |

can you provide a link to the picture of the gold wing parts? Here is the ebay search page...you just need 1984-1987 Honda Goldwing 1200 air breather box....probably available outside ebay and at the picker part. http://www.ebay.com/sch/i.html?_odkw=goldw...ox&_sacat=0 |
