Air Filter PODS for Goldwings (GL1100 in particular)

Postby tonyincny » Sat Aug 02, 2014 4:22 pm



Forgive an old codger if this has been covered. I tried searching and couldn't find any info about the topic.
But, I was wondering if anyone had converted their older Goldwing (like my GL1100) from the airbox to air filter pods. From what I can see, the advantage isn't so much in power or performance but, rather, in freeing up some space under the frame. I pulled out the airbox on my 1985 Shadow and now can get to a lot more things than before.
It looks to be a bit more difficult on my GL1100, though, since the pods would have to be along the centerline of the bike.

No can do on these bikes with the existing carbs. The air chamber is an integral part of the carb assembly. Mounting, fuel ports etc. Russell Washington used to sell (I don't know if it is still available) a replacement carb assembly from www.randaksblog.com that allows you to install carbs outside the false tank. Then there are single carb replacement manifolds available.

Even changing over to a single carb (at least the few I've seen) requires the air intake to be in about the same place as the factory airbox. I thought about how it would look/work with pods and I can't see it as a possibility from a strict physics perspective. I'm thinking the air intake plenum supports the runners and carbs in addition to the other functions it provides ...
I am wrong as often as I am right concerning what is wrong with someone else' motorcycle without having seen the machine in person. Guessing with limited information, as to the source of the trouble, is sketchy at best.

You could probably have a new air box fabricated with a 90 degree inlet to accept a filter pod. It would likely be expensive to make out of aluminum and I doubt you would see any benefit. The factory air box has a tight seal that keeps out moisture. I've seen where folks has converted to single carbs, they don't perform nearly as well as a properly tuned 4 carb setup. The dual weber manifold setup is nice but it won't work on a fairing bike without hacking it up. It would be a slick setup on a naked wing..

Thanks guys. I was a bit perplexed on how to add pods but was hoping someone out there had a miracle cure. Maybe they just haven't posted yet. :D

I just had another thought. It hurt but here it is.
Of course there will be some degradation in performance by converting to a single carb. Just as an eight cylinder car will perform better with a carb for each cylinder as compared to a single carb. But, all cars (with carburetors) come with just a single carb from the factory.
Does a Goldwing really require or does a Goldwing owner really require that level of performance that four carburetors give?
Wouldn't you agree that most Goldwing owners are fairly casual drivers just as they drive their passenger cars? Therefore, as they accelerate up to highway speeds then settle in at 65 mph or 70 mph, why do they need four carburetors? Is all that extra and complex equipment necessary? Is maintaining the tuning and balancing of four carburetors really necessary when a single carburetor will give the performance necessary for everyday driving? A Goldwing isn't a sport bike and it isn't driven as such. So, again, why four carbs?
A YouTube search of "GL1100 single carb" gives some videos and some insight into performing such a changeover.

No they certainly don't.
