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 balanced and tuned carbs after I put them on and watched my idle very closely and really didn't see much of a differance between putting the tops on the filters and the air box top with the horns. Driveablilty wise there are no flat spots that I can tell. We have some pretty steep canyon roads here in Boulder and it pulled real strong from low RPMs.
I probably spent less then $75 on the project. The 356 or 912 air cleaners I saw for sale were $200 plus and needed adapter plates to work with Webers, and didn't seem to quite fit anyway. I thought of motorcycles because I have a BMW R90/6 which is essentially half type 4 engine and its super quiet. BMW boxes need more fabrication to fit, so just kept looking and found these. The earlier Goldwing boxes are not as tall and might work also Attached image(s) |
