Agreed! But he does say " or best offer" So if someone is interested try it. Personally I'd rather build my own some day.

Thats way too high , that looks like Copper Water Pipe . ..Thin... soft ... I bet Hot and Cold Temps would be hard to keep the flow right inside that . I have Owned , and Built many street rods , and the flow inside an Intake is real touchy . you might could cover it with like Pipe Insulation or something and help it some. .....but , I think we could measure a complete set of Goldwing carbs all together , and most likely build that for 1/3 that price or less. ....

It does look like copper pipe.
That left fitting looks like a street 90.

I'm no hot rodder, nor have I ever built any part for an engine (there, those are my qualifications) but isn't that manifold the same size pipe from inlet at the carb to all four manifold inlets? Can you really get the correct mixture to flow to all four carbs with this setup? :ahem:

it takes some real planning and a good head , to figure the air/fuel mixture or flow at any single point inside there . and WAY above me... but I do know that a Tiny lip like between the Intake and the hole in the Head can make a BIG difference in flow. But I have read up on this quite a bit , and the Older VW's was almost the same CC's and Engine design as a Goldwing . and you can look at the Intake on the VW's and a single barrel Carb. and they was smooth and dependable as most anything for that time. so, I think that might be a good starting point ... might need some tweeking ......but , I really think it would work....... BUT , I also think , Heat and Cold would be a big deal .... and I wouldn't use that thin Copper Pipe.
ease of maitinence and the fusration of getting stock carbs clean enough to wor good and stay that way ....i like the stock set up and im into cleaning somee 771000 carbs now there not very user friendly but they are closer to fine racing setup as to ease of maitinence..
i wouldnt mind have my touring bike set up with a nice single carb setup for reliability but its seems hard to get the right setup ....the worst thing about goldwing stock carbs is they tend to leak gas in the motor when not right :mrgreen:

It's simplicity.
One idle mixture.
No syncing needed.
Larger jets so less prone to clogging.
Easier to rebuild.
I would like to toy with a single setup some day.
Maybe one will drop in my lap, I sure can't afford what they sell for.

I have this friend who was into Drag Racing for many years... now that he is up in years he has quit. and I think I'm gonna go down and see him one day and see if he's got a good Carb. for me to use on my Wing. I think I could build an Intake fairly easy, but I need the Carb I'm gonna use first .
im just about at that point my 77 1000 rack is in horrible shape and i made it worst with breaking one of the float towers ....im always reading stuff on this and it seems that the VW type 3 intake is the best start and it seems that the weber 28 36 carb is the one that the secondary comes in late enough to match the wing motor .....

A cheap manifold could easily be built from PVC pipe with radiator hoses as couplings to a plenum. This would allow easy modifications until a functional model is achieved.
Call me Ishmael, but why not try for a 2 bbl or even 4 bbl manifold? I would bet a wing with a carter quad could get good fuel mileage and when needed scream down the road. Maybe thats like putting an 850 dbl pumper on a 289 but maybe worth a try and carbs are EZ to tune.
the weber i was talking about is a two barrel carb that works like a four barrel carb ..... :mrgreen:

The possibilities are endless. VW had a two carb system on some of the Beetles. That too could be adapted. If I could find affordable side draft SU carbs , one on either side would be cool.

When all this Snow melts a little , and temps get above freezing , I'm gonna do some planning on this ... I would love to do this... My Goldwing Starts Good......and Runs Good , ABOVE 2,000 RPMs , BUT , pulling out , or in town , redlight to redlight
it's not all that great , and I know it's the Carbs. I cleaned them out ... and checked everything, and set everything , and bought gauges and synchronize them as best I could . but , still not right . and I have been looking everywhere , but, a set of Carbs that look better than mine are High Dollar ... and I just can't afford them. I can find a Car Carb for a fraction of the price of a set for a Goldwing .

sounds great ....im realy wanting to get one of those type 3 VW manifolds ...from there its just the tubes to heads ....but a 28-36 weber is not a cheap carb ....
so i might do something cheaper first....cant wait for you to get started sledge... :mrgreen:

I have a VW engine. I wonder how it would run with a set of wing carbs? I need to get myself cloned to take care of all these projects!

there is a place in Knoxville , and it's not just here ... they are around , called , Pull-A-Part , you have to remove the parts yourself, but what Prices they have. like a ( 1 Barrel Carb , $18.10 ) ( 2 Barrel , $21.71 ) ( 4 Barrel , $25.34 ) no matter what kind of Carb , no matter what it's on..... same price . when the weather breaks some, I'm going down to Knoxville and check this place out. and if I can find what I think is a good Carb , then, I can work on the Intake Design from there. I have looked on Pull-A-Part site , and there are kinda all over. ..... like say a V6 Motor , they are the same price , if it's in a Ford , or a BMW . check them out.
