why keep it normal 78 goldwing slow build...

I don't think there is an after market airbox. I've not seen one anyway. CXman may know or ask that at NGWclub maybe. I do have a K&N filter in mine that came in my parts bike though.

Most swear by the Honda head gasket. Search carefully and you can find them at a reasonable price. I've never seen an aftermarket airbox. Probably because it is hidden in the shelter. BTW, before you put it back on, put something like screen wire over the snout to keep mice from invading in the winter time. They love to nest in them.

Thats a good idea

I saw someone 3D printing an adapter plate to put a big pod filter on there instead of the air box. Not sure if it would be much of an improvement.

Any change to the restriction given by the stock airbox (less or more) on four ganged CV carbs is going to cause problems. Rejetting a single carb isn't badm but rejetting a system with four ganged CV carbs that have 6 jets in each carbs, and takes a bit of work to get them on and off, is no good. Plus, beyond just getting idle right you would really need a dyno to get full performance back. Best to clean up the stock can, paint it as desired, and use clean paper (not K&N) filters. Going single-carb seems easier, but why would Honda make it harder (and cost them more to manufacture) using four? The only single carb setups that I have seen with good idle, acceleration, and top end on GL1000s were mounted on blowers. And tuned by carb and GL1000 experts on a dyno.

I've read enough good about singles to give a try. I agree it probably wont be as good as stock... at my skill level I dont think I'll notice much or care about the small decline, I just cruise country roads, nd I have fun fiddling around with things.

I just did a search on single carb conversions and there sure is a lot of information. One used a modified VW manifold and plenum and the rest fabricated a plenum (or not) and the short tubes. There's a bunch on ebay and I ssupect taht CXman (Murray of Murray's carbs) probably has a conversion kit.

Looks like it will be a fair amount of work to get it right, but interesting and supposedly makes a difference. Good luck with that.

Murray did have some, he cant get carbs at the moment for his kit. I can get a used one and rebuild it or maybe a clone....some good reviews from vw guys on them.

Check on the old wing sites, too. I've seen several that have taken them off and put them up for sale.

I had one of CXmans setups on mine. I could not get my stock carb setup to run right even after a Randakk kit and several tries. Probably mostly me but I got frustrated. Put Murray’s carb on there and I was up and running.

The stock carbs are better - but they have to be perfect or damn near it to not be a PITA. Mine were in and out 5X or more when I rebuilt them so I can understand the just wanting to simplify. I know how good the bike can run so I stubbornly worked to get them right, but if a single carb got me to even 80% I might have taken that by 3rd removal LOL.

If you are looking for a single carb manifold, try to find one with an inlet/outlet for radiator water circulation. One of the first pioneers of these conversions realized you needed warm water circulation through the manifold to make the car sourced carb work correctly. He made and sold manifolds for many years and sometimes you can find one on EBay or some of the forums. When we built the 79 wing I found one of his manifolds at a swap meet. I used a Solex carb and after getting the jetting and fuel regulation correct it ran very well. You might loose a bit of power over the stock carbs, but honestly it was not noticeable. It would run 80 mph all day long and start instantly.
