For me the induction noise of carbs is too loud. So I went looking for a solution and I thought I would share what I found and trying. 1985 Honda 1200 Goldwing air cleaners.
They seem to be working great. Nice deep sound and quieter. The air horns on top are about 1"x 1 1/2" each. Combined they are bigger then 1 throat of the carb. I don't feel any reduction in power and idle seems about the same. Engine is a basic rebuilt 1.7 to 2.0L specs with carb cam and hydralic lifters. Cheap too. shipping cost more than the air boxes themselves. A little fabrication of a mounting plate, but pretty much bolt on. Linkage clears. Attached image(s) |

I just finished with the same mod and couldn't be happier. Cost of the filter boxes off eBay was $24 each including shipping and I used 85 Gold Wing Aspencade 1200cc boxes. I've driven about 10 miles and did not notice any changes in A/F, idle speed or power. I did notice a HUGE reduction of intake noise and now I can hear the exhaust. The ultimate test is driving up an incline on the highway with the windows up which I will attempt sometime before WCR. Below are a few pictures of how it goes together...basically as RonD describes. And thanks to Keith914 who gave me his lessons learned. Mounting plate made from 1/8" aluminum: Before installing the old K&N-type filter. You can't see it here but I had to grind off the ends of the chrome bottom plate to fit the GW air box opening. With filter cover installed...I had to weld in a longer 1/4-20 bolt for the wing nut and dimple the top of the chrome top to make it all fit properly: |
