I use stone filters as well.
I've had excellent results with PrimeLine filters. Very small and the clear plastic case has remained "clear" on all that I've'd used.

Hi, I really enjoyed your post. I just bought a 77 GL1000 which came with a webber 32/36 progressive, but which won't run below 2,000RPM. AFter doing a bunch of research, it looks like the carb is just too big for the engine CC. The 2 barrel 32 dft looks like a much better option due to the smaller Venturi, but when I went looking to buy one, I couldn't fine it anywhere. Could you please tell me where you bought yours from?

The link to Tom Langdon's page for the carburetor:

I suggest reading the link below (and the wording above it) which is also on the page from the link above.


*must be installed on a heated inlet manifold. For more info, check out our tech tips!
http://www.langdonsstovebolt.com/tech/why-you-need-to-heat-your-intake-manifold/


The asterisked statement is not optional.
__________________________________________________


Additionally, you'll need a chainsaw file if you don't already have means to elongate the mounting holes of the DFT to fit the base of the manifold you already have.


Do you have any pictures of you're conversion?
If there is anything at all that will help you most in getting you squared-away it will be pictures detailed pictures.


You're certainly on the right track in going with the DFT versus DGV.
The carburetor (DFT32) is right on. Your manifold is the question at this point.
Does it have any provisions for heating with fluid?
Does it use the factory inlet elbows?
...

Thanks for the reply. It uses stock inlet elbows. Have attached a picture. Does not look like it will accommodate a heating system. Deal breaker? I was going to refurbish the stock carbs which came in a crate with the bike, but the chassis looks damaged, which is why I thought I would go for an improved single carb setup.

Went ahead and placed the order for the new carb. We'll address the manifold heating issue when I get there. Sounds like I need to weld a U channel under the manifold and divert the cooling system fluid through it. Wish me luck!

I would reduce the plenum volume as much as possible from what I can see.
I would also weld a coolant chamber to the bottom of it.
I would insulate the runner's also. "Insulate" as in wrap them with something to retain heat.

Pot holders ...you know, the kind you use in the oven is a good start. They come in all sorts of styles and are inexpensive. We know they work, right? Can secure them with children's bicycle top frame tube padding covers.

Of course, you could one-off your own ideas.

The point is that we're not trying to isolate the manifold from the heat available via the factory elbows. Honda heated them elbows by design for the exact same reasoning we're applying heat to plenum floor and walls and then retain what we can for the runners via insulation/wrapping. It must be a thermal wrap and not simply a cosmetic application of something "cool" looking, ...no pun intended.

Great feedback, will be sure to take it all into account. Just left home for a 2 week road-trip, but parts are on order and almost can't wait for vacation to be over so that I can start the assembly and tinkering process! Again, thanks for the help.

Hello WestGL
I have a nice 1976 Honda Goldwing with carb issues as well. Have been running 1100 carbs but runner #4 is ice cold! Me thinks it is due to the float not stopping the fuel flow and excess fuel is flowing into that cylinder. The #4 spark plug is certainly very rich looking.

So I have decided to go the collaborative effort route and install the single 32/32 (Toms) carb and VW Type 4 manifold I will also use the Napa Gold High Pressure fuel hose for the runners. Have some questions:
1. Is this still the best carb 32/32 from Toms for this application?

2. I live in Texas, so perhaps heating the manifold would not even be necessary.

Anyways, looking forward to trying this out. Many years ago I had a weber carb conversion on a 76 Toyota Landcruiser and it worked great,

Thanx for any input you (or anyone) could provide.

my Weber now works 100 percent perfectly

1982 gl1100 Aspencade. 2bbl Weber. stock fuel pump and filter. K&N filter Assy. CC Products tuned and heated intake, stock runners. Vance and Hines Rumblers. 1975 cams. Nology multiplying wires.
PO, and I both found unacceptable overfueling, fouling, at low speeds.
I turned the idle jet in 1/4 turn at a time and it continually got better. finally it bottomed out... and the bike runs like a new car. one push starting, perfectly flat idle, 40 MPG + under 65mph. The only issue I have is I think its still a bit rich in the secondary, as mileage over 70 is poor, 25 ish. the secondary with just me on it begins to open about 75 mph, and with the wife on, about 70.
I am sure I have lost some 70 MPH and up torque, compared to my stock gl1100s, BUT...
From stop light to stop light, this thing is a monster. I could break the rear tire loose on acceleration! Now I have new rubber I haven't tried it again, but wow.
in 1st gear, at 3000 RPM, when that secondary opens this thing is gone. And you should hear it! If anyone ever doubts the GL1100 being capable of performance, they are wrong. This is the best thing to ever happen to a Goldwing. I got a lifetime ban from NGW for condemning those worthless stock carbs, and I am glad to not know them any more. A 2bbl heated carb solves everything. My only complaint? air noise. while that 2bbl moan is cool it gets old.
