Tsuyoshi; I just aquired a dual Kiehnin (RS) setup and was wondering If you may have a exploded view of the carbs? He said they were missing a 'shell' on one of the carbs (?) To me it doesn't look like anything is missing. Really ANY INFO on these would be appreciated!! It was said that these carbs were used on the Goldwing motorcycles.(?)

Hi errol,
I have a exploded view of dual Keihin CV carbs. but I don't have scanner. I am not sure what is "shell" means. Is it rubber diaphragm?
I would like to see keihin carbs of Goldwing. Do you have pictures of the carbs? Please let me see it. I think It is very similar CV carb in to RS carbs, but is not identioal to RS carbs.
I will try to use scanner for copy in job Please e-mail me. and let me know your e-mail address.
Tsuyoshi.

Tsuyoshi, your RS ROCKS!

Can you get us some more photos of the engine and interior?

Hi, Tsuyoshi and Errol, I sold Errol the carbs. By shell I meant the outer casing of the carb. The actual carb itself when the parts inside are taken out. It needs this because of the stripped out bolt hole I told you about. Adrian told me once what all those carbs were found on, you could probably find out from him. I hope you have good luck with them. Tony T.

So you're talking about the carb body when you say they need a new one.
Similar (though not identical) CV carbs were used on quite a number of different models. Goldwing, Coupe 7/9, N360, Z360 etc.
I know that if you get Goldwing GL1000 rebuild kits you get the gaskets and most of the o-rings you need.
Here's an expanded pic of the bottom half of a coupe carb. Note the two diaphragms (9 and 10). The book calls number 10 an economiser (9 is the accelerator pump). I'm not 100% sure what it does (even though I had my carbs apart the other week I didn't really investigate it), but I would assume it's an economy device of some sort. The RS carbs I have have got this bit, but a set of quads I have do not. I can't say if all RS carbs have them or not and thus whether all RS carbs are the same. I don't know if the Goldwing carbs are identical to any RS carbs but as I said, the rebuild kit does work.

My guess on 'economiser'.

Holly brand carbs have a 'power valve' that has been called an 'economiser valve' in some of the manuals. The valve uses an internal vacuum signal to open for fuel enrichment at loads higher than basic cruising. This lets you cruise at leaner mixtures for better fuel economy, but still have power when you need it(up hills, for example). Different vacuum level valves are available to adjust for different engine characteristics (Big cams, high rise intakes, headers, etc.)

If this is what that part is, and you can get other values, it can be a good tuning aid.

Errol
Have you considered installing a a HeliCoil or using Devcon Aluminum Putty (F)to repair the stripped hole ?
Both work well and are relatively inexpensive.

Sorry for not reading the posts....I met a guy that sells old/new motorcycle parts and he's going to try and pull up all the microfische on the gl1000 carbs for different jet and needle sizes. I finally found that stripped hole,.. going to epoxy a stud in there. Was thinking about enlarging the fuel inlet ports (they're really tiny!!) and threading them to accept angled nipples and then attaching a fuelrail to them on the outside so i could use the cone style air filters because there wasn't a filter top when i recieved these. UNLESS SOMEBODY HAS THE TOP PIECE OF THE AIR FILTER HOUSING????
(looking at it more, I'll need to use the filter base for the vacume signal port that opens the slide)

Both have that economizer 'doohicky' but only one accelerator pump, and the area that attaches to the filter base looks slightly different. (just out of curiosity..in the pic, shouldn't those floats be turned upsidedown??) Charles: i think you'r right, It's right below the needle and jet assembly.
Anyhow; thank you all for the info, You just don't realize what a goldmine of info is here on the site!! errol

By Adrian (Civicguru) (203.42.97.227) on Friday, April 20, 2001 - 05:18 pm:

There should only be one accelerator pump. There is a pipe that takes the fuel across to the other carb. As it says, that's an exploded coupe carb, not exactly the same, but the design is very similar.

By Charles (139.134.174.87) on Friday, April 20, 2001 - 10:01 pm:

The economiser is a power valve, even the later model Hondas still have this and the honda manuals call it a power valve. Check out the carbs on the D15B and ES/ET engines. I am sure you would only need to replace the spring to increase or decrease the richness. You can also replace the dashpot springs with a softer variety for quicker throttle response.

Hi Errol,
Long sentence English is difficult for me
In short, what is number that your lost part in above exploded view? Do you need exact RS carb's exploded view ? And do you want air cleaner base plate? Please let me know.

Yoshi.

Errol is missing the clamp on cover. They were sold to me without it. Should be simple to make one from aluminum, but the cone filter idea sounds better. I had them on my car and it ran fine save leaking a little around the filter base, because one of the holes that it bolts to is stripped out. I imagine getting a new body for the carb in question and new o-rings would solve this. Good Luck, and I hope you can work it out, ...Tony T.
