The conditions are less than ideal but a good project helps make that time go by a little faster! Please send some of that SanAntonio heat up our way!!! :lol:

I remember once hearing (before seeing) a 1200 with straight pipes.... before I saw it I thought what the H is that!

It's time to remove this GoldWing's carburetors and clean'em up, inside and out.
-

Initially, the float bowl on all carbs looks pretty good - not what was expected:
-
Image
-
Image
-
-
Using air superiority, we've located the low speed jets!:
-
Image
-
-
Those need to be removed to ensure they are clean and I pray they are the fabled "press in" type! (They are! action1 ) Using a drywall screw and small vice grips we can pop'em right out!:
-
Image
-
-
A bird's eye view looking down with the low speed jet removed:
-
Image
-
Image
-
-
No light was visible when looking through them so first they'll get a short soak in penetrating oil:
-
Image
-
Image
-
-
Then they got a wonderful 30 minute experience in a RevereWare hot tub.
Vinegar and Citrus Stripping Gel are added to the bathwater:
-
Image
-
-
And once removed they are really, really clean and light is visible through all drilled ports:
Image
-
-
The ports in the jets are so tiny that none of these wires would fit through them (bread tie, bread tie sanded to be thinner, an led bulb with a rigid filed lead):
-
Image
-
-
Floats were then adjusted to correct setting (little plug for Randakk's float setting tool here!):
-
Image
-
-
Rack was then reinstalled on the engine with 4 new intake elbow o-rings:
-
Image
-
-
The good news: it idles on it's own and doesn't quit.
The bad news: it still doesn't run good and more exploration is needed.
Here's the latest video after the carb rack was reinstalled:

It's zero degrees here in Colton, NY.

It’s going to kick a little when you rev it without the filter on there. Probably needs a synch too, and if it wasn’t fully warmed up, that could be some of it. You’re probably pretty close.

You are Limited in space, a few years ago someone here built a box which angled forward and then used a standard flat pleated car filter.
Whatever I suggest here should be given ample time for a moderator to delicately correct. I apologize in advance.

Jerry,
Carbs look good, here are some things I have learned:
- an electric guitar e-string is about .007" diameter and will go through the low speed jet holes. I cheap set of strings is about $5 at the local music store. If you are out in the boonies PM your address and I will mail a piece to you.
- Oil the felt seals around the idle shaft. I tape the round end of the carb to a shop vac and put my hand on the other end of the carb. Then spray Liquid Wrench White Lithium aerosol oil around the shaft. This will seal up the shaft and lubricate it at the same time. You can do the choke shafts too, not only does it seal it but it will make the the throttle move nice and smooth.
- Straw test on the vacuum slides. The vacuum pistons must go up and down together. With the Carburetor in your hand, use a straw to blow into the air port on the intake side of the venturi. This is the port that runs to the under side of the slide piston. This will simulate the pressure differential the piston sees when the the engine is running. The piston needs to be able to rise on air pressure alone. If not the engine will not come off idle very well and will run poorly at speed.
Please excuse me if you already knew this.

It looks cold in Colton. My Subaru said it was 58 and the sun was out today in Seattle. JimP

Edit: does the drywall screw damage the low speed jet?

Synch is on the list, and yes, space is really at a premium on this bike!

JamesPal,
All good info from you and I will make notes of those! I'll see if guitar string :guitar can be sourced in my area and if not I'll pm you (thanks!) The drywall screw only makes a small bite mark in the end of the jet and doesn't even come close to the middle where the tiniest port is. The press-in jets in this rack weren't any more stubborn than the ones in the 1981 - not bad at all.

The bike starts incredibly fast and it does idle/run better (video link below)
There's a nice storm brewing over the area and if we don't get buried alive another test during actual daylight will take place.
A little gremlin is still hiding somewhere and I'll find it.
It's a little breezy and -8 degrees Fahrenheit in Colton, NY.
Bundle up!
