Gold Wing single carb solution

Post by truefire5 » Sun Aug 20, 2017 11:01 am



- I converted my troublesome quad-carb solution on my 1976 Goldwing GL 1000 LTD to a single carb solution which I wanted to share
- For me it was an outstanding solution that significantly simplified by carb maintenance.
NOTE: I'm not related, nor do I have any financial interests in this solution - simply sharing for my fellow Goldwing owners)
- Kit came with quad to single carb unit as well as a single carb (basically staple VW-style carborator).

Very interesting! How long did it take to install it? Was the carb fairly well adjusted initially, or did you have to do a fair amount of tweaking? Lastly, :lol: Is there still room for the tool tray?

Thanks for sharing.

Easy to install once old carbs were removed. Took about two hours.
- Original choke cable was removed.
- Bolt made to secure throttle cable (see photo): I had to cut a bolt and drill a hole through the bolt head and threaded it so it would hold the throttle cable.
- I purchased air filter that does take up space where the tool kit was (see photo). BUT, you can purchase different sizes or adapt a smaller one so the kit would fit. I placed my kit in the side panel of the false tank as there was plenty of space there. :-)

Other than that, incredibly easy - once it is set, I've never had to mess with it at all. Best off, if I ever need a replacement carb, its a very common stock item.

I hope that helps :-)

For seemingly decades, there has been many many discussions/blogs on the pros and cons of four carbs with individual runners vs one carb and a manifold feeding the four runners.
I'm curious, now that you a single carb to avoid a lack of synchronization and by retaining the original four curved runners you still have the vacuum ports, what does a synch tool show the vacuum difference is between inlet ports? That will illustrate any remaining imbalance due to the new manifold.
And I mean, don't just wave your hands and talk about it, but show us the gauges.
Is that possible? Can you do that for us?

Thanks.

Have a nice day! :)

Greetings folks, Yes, I too would like to know the answer, but just or even more important how low can you set the idle with it remaining steady at idle. Also now that you have had it for a bit, is there really any difference in fuel use?
Thanks for posting

I wasn't really sure what the advantage was for multiple carbs either, especially given the added complexity. If you've ever watched Engineering Explained on YouTube, he has a good video that covers this topic. I'm a 'keep it simple' person so given a choice I'd rather stick with a single carb, plus I just don't drive my vehicles to 10/10ths where I realize the advantage of multiple carbs.

Please report back in, say, 40-50,000 miles. I'd be concerned about those welds, and how well they hold up to carrying the weight and vibration of the carb. It reminds me of an upside down pendulum.

Price seems to be reasonable considering the cost of having a rack of carbs cleaned with replacement inlet needle valves etc. can easily exceed that at a motorcycle repair shop up here.

I just ordered one of these 4-to-1 setups. I'll post results eventually. My bike is a neglected 82 I bought in Vegas last month. Carbs were already out with missing parts. This seems a simple solution if it works. <$250 delivered, assuming it gets delivered. :)

Brakes were real bad, new parts ordered. Instruments are hanging loose. Installed new battery yesterday and lights mostly work. Intend to semi-cafe this bike.

Also have an 83 Aspencade converted to standard waiting for me in Quincy, IL. Also needs carb work but rideable. I'll go get it in the spring.

Pictures of the 82 later.

Hi wingers, I too have similar questions as to difference if any in fuel consumption and how low you can now set for a smooth idle. It also appears from the photo that only on cable is used for the throttle, not both the push and pull. Is that correct, and if so does it matter which cable is used? Also the chock appears to now have an electric connection. Does it just use a keyed 12V hot?

According to the instructions for the site from which I ordered, only the pull cable is used. The push (close) cable should be deleted to avoid entanglement. The choke runs off switched 12v power.

I've read as much I could find today and would strongly consider a stock carb rebuild if I had a complete set from which to start.
