Single Carb Conversion 2 Barrel Progressive Holley,Weber 740 carb

[westgl]

I pulled the New Single Carb. off

Referred to as a GL11-1 meaning GL1100 w/1 carb.

I pulled the new 1-carb off of the VW Manifold.

I wanted to see how easy it was going to be in comparison

From the top of the frame, I took a socket wrench & 8mm socket,

down over the top of the new carb and was able to get to all 4ea mounting nuts.

This was very easy to remove the new carb. it took me less than 5 minutes.

And i could get to all 4ea nuts from the top with a 8mm socket wrench how easy is that?

The new Throttle attachment is Also Much easier to remove than OEM
I am Only using the PULL Cable, the Carb has, 3 return springs, so I am not using the other throttle cable, It is not needed.

But!!!
My thought is I will look at and inspect the second throttle cable,

that second cable That I am not using, the Pull to close throttle cable, may be used as a back up cable, or if out on the road a spare.

I am not sure about that yet till I look at it more closely

 

[westgl]

I re-Routed My Pull Throttle cable through the Front above the radiator, This works well, But the OEM cable is a little to long.

I will need to research this to get a shorter cable, about 4" or so shorter should do it
I will have to measure how much shorter then go through some Cable Manufacturer catalogs like Motion pro and some others, to get the perfect Length of cable.

I may Cut the cable to length, and crimp/swedge on a new cable end

OR

The better way, that is cheaper, and a DIY,
Is to,

High Temp Silver Solder, a new end on.
Note: Regular Solder is to soft and Wont hold.

Get a piece of Brass rod the diameter needed to fit in the Throttle Uni-Kit.

Cut the Brass rod to length, drill hole the size of the cable dia. for a tight fit.

Then High temp silver solder, it should last a very long time.

My Ultimate Goal in doing this Single Carb. Conversion.

Is to have my GL1100 Better, to Much Better than it was in the Completely re-built stock OEM format that I had it in, prior to single carb. conversion.

Before the Single carb conversion I was not real happy with the GL1100 and was thinking about dumping it, getting rid of it.

I have a GL1200 that at that time ran better, Now the GL11-1 runs much better than the GL1200.

What will my GL1200 be like if i do this 1carb. mod to it? Whow!!!

I was thinking of Selling my GL1100, before the 1-carb conversion to the highest bidder just to get rid of it, i was not happy with it

I had already spent a lot of money on it, to get as far as it was by re-building everything.

Including those OEM-4 carbs (Dang Cod catchers)

But People Don't tell you, when you start on those OEM-4 carbs, How much work is Involved, After the Rebuild, Just keeping those OEM 4 carbs going.

I have had to pull the rack after a 4 month, winter storage, Even with stabil in the tank

Ultimate Goal Has Been Achieved,

I would Not sell my GL11-1 now at all, it is too Much Fun.

OK went for a ride, had a minor Snafu.

I was riding and noticed Temp Gauge was pegged, Hot or Low Hot, just right before the Red line,

Gas gauge went from start of ride at 3/4 tank, to Full or Past Full, while riding.

I think i have the dreaded,

7-Volt Regulator Malfunction!

Nice!!

 

[joedrum]

yes exactly .... westgl I couldmt agree more on the complete satisfaction ... on my bike I did shorten the outside cable sleeve to the adjustable middle section ....did so far cimp and end on it and now a throttle spring on carb ... cable mounted to heat shield top frame mount it worked great and require no special pieces

sheeh 7volt reg :cheeky:

Just came back another test Ride this morning.

Bike ran great, No Leaks of fuel Any where, or Hydrolock

I can feel that the engine is running Great

I wish i could figure out how to post a video of a running bike.

But let me let the engine speak for it self .

Here is a pic. of two plugs, the other side looked the same.

They are out of the two right side Cylinders

That is about 150miles on the GL11-1 conversion

Riding on Primary some and going between the Primary and secondary.

One plug in each cyl. is slightly more tan than the other, but the other is still burning very good.

How do they look?

These pic.'s dont do it justice

They look better in person.

The engine is running real happy

 

[westgl]

Here is the Spark plugs from the Left side Cyl.'s

They are a very nice Tan, slightly darker tan, or on the very Slightly Richer side of perfect.

Not running Lean at all, or running to rich, they are a perfect example

These were taken in very bright, & direct sunlight

I should have put a white piece of paper behind the plugs,

as that back ground makes then look slightly lighter than they really are.

Engine is very happy

I been following this thread since the beginning, and am amazed at some of the ingenuity youse guys have, and the determination to figure it out. Kudos! :clapping:
On the plugs, tho....are those new plugs, or the ones that were in it before the carb change?
Either way, the one on the left in this pic looks to be burnin some oil...

They are out of the two right side Cylinders

The plugs on the OTHER side look otay, but well used? k:

 

[westgl]

They are more than 2-years old, and have a bunch of miles?? on them.

I will be changing them soon, they are worn

Well, in that case, they don't look too bad at all! :mrgreen:
Perhaps a new set would be beneficial at this point. I just recently put new plugs in mine...the old ones had been in it since I bought it...in '08... :blush: The new plugs made a HUGE difference in the ease of start, and it runs better on the road. :good:

 

[westgl]

The engine was Frozen, Solid, when I got the Bike.

I am debating on whether or not to Do a Engine flush, to add, about a 1/2 to 1 quart of ATF to engine oil to condition the inside of engine, & lower Oil rings.

Draining out that much oil, and then add the ATF, to bring up to high side of Full

Then ride bike, with mix in it, for say 300-miles, while riding it, Oh! so lightly, on the throttle, this would also clean out that starter clutch too.

Then Change oil & Filter

If there is anyone interested in This, or, a Single Carb Conversion

I have been posting Over at the Steve Saunders Site More often than here.

The reason for that, was there are two other people over there, that have also completed the Same 1-carb. conversion,

Using the 32DFT, and there are 2 more guys gather parts now to start there conversion.

These people have had input, that is not listed over here.

There maybe some tid bits, over there that will help, someone.

They have a lot of questions over there

man im sure glad the word getting out on this ... it is such a great mod to the oldwing .... westgl really know how to spread the word .....

Joe ,

Like wildfire, thing is Joe most people will be to scared to try it, thinking about it and decide to wait.

Then kick them self in the Colon, once they find out how great it is, you have to be very double jointed for that, i've tried.

I dont this this should be hidden away, it is such a great upgrade.

If You were brand new to Goldwings and new nothing about them, and test rode both a GL11-1 and a GL11-4.

Which one do you think you would pick.

Not Knowing that the Oem 4 carb. rack Anchor, is a Royal pain in the buttinki,

Only going by seat of pants, Riding Impressions, which would you pick

I think that If i would have ridden the single carb. I would gone for it, in a heart beat.

It feels like so much bike. The engine now fill the voids

You have a Built GL12-1, the GL1200 engine is already a more torquey, & powerful engine, right from the start, More than my GL1100 was stock.

So I cannot Imagine how much better, the GL1200 is in the new format of a GL12-1.

My GL11-4 was Noticeably slower than the GL12-4, to the point of me not enjoying the ride as much on the GL11-4, take off from a stop was slow and pokie, the higher revving to get a way from the stop.

That has all changed, the GL11-1 seems like the difference between the GL11-4 and the GL12-4

The difference between the GL11-1 and the GL12-4, the gap has been narrowed to the point that i would give the win to the GL11-1

Knowing what I know now about the GL11-1,

I would pay More to get the Bike, with the 1-Carb. & vw manie on there.

Today,

No Fuel Leaks, :mrgreen:

I Finally modded my Throttle Cable Hold Bracket.

I had to Make Fire, and used the Welder for first time at the new shop, worked good.

I made some longer legs for mounting it, and bent the end that holds the cable a little so that the flow of the bracket matches the flow of the throttle cable.

I also Ground off about 3/16" were the cable mounts to it, this brought the cable adjustment closer to the carb. it gave me a little slack in the throttle cable, which is what i was after,

Throttle cable was a little tight and some times idle would a little higher than I wanted. Now it returns to set Idle every time.

As my throttle cable had no slack, and had no adjustment left, for making slack, only had adjustment to take slack out.

Now i have adjustment both ways, adjust for more or less slack if needed.

I was going to adjust the Idle mixture screw today, but after I finished with the work above it was sooo HOT and I was sweating profusely, like Niagara Falls, or is that Viagra Falls.

I have a good rebiult set of carbs but if they ever give me any trouble I will go this route..Thanks westgl , Joe , Dan and any other contributors for all your efforts putting this down in type/pictures.
Maybe I`ll just pick up a type 4 manifold and put it in the closet just in case.

 

[dan filipi]

I tried reading some of the posts at Saunders but that keyword link popup crap and the advertisements just rub me wrong.

I'll stick with what we have here or muddle my way through it on my own.

I hope this us all true and I'm close to pulling the trigger to try this. But, I'm going sow some caution. Westgl had a frozen engine. Is it possible that the carb switch came near the same time that the rings in the 1100 were finally seating and thereby giving the impression that this setup is better?? Like I said, I hope I'm wrong. It would nice if there was a well tuned 1100 naked to compare it to nearby. I have an 1100 in the wings with 90000 miles and only ridden three times for a couple miles each time. I held the hammer down once and was still pulling at 117 in fourth gear. It was torquey, not as much as my 1200, but my 1200 is like Joes, modified. Butt dynos can be accurate, but most times our butts, like our egos, tell us what we want to hear. I'm going to keep waiting for more rides and reports. Joe will soon have a 1200 to compare rides too. It has been fun following along, so don't take this the wrong way anyone. Even if it does end up a tad less than the stock setup, I think lots of people will opt for it for less complications in the long run.

 

[westgl]

Redards to the, 4-carb rack, when you have worked on them enough to be comfortable, and if you have more than one bike that is running, you will become a season vet with those DXXX carbs fast,, it becomes easy, (once you tell your self, OK just do it again) to pull them out and put them back in, I can do them fast, just a PITA,

But I dont feel I should have to be working on those carbs, often,

I feel like the rest of the Bike is Durable, it can go the miles with out a lot of care once brought back to rebuilt status,

Even if PO was SFB SH# T For Brains, it can still be sorted out, and still have, a durable machine.

Brother in laws bike had PO do a slick 50 treatment on a 75' GL1000, clutch needed replacement.

The carbs Will Not allow you to Just Ride the Bike, with out worries. they will always need attention from time to time.

Coming out of winter, Hibernation, carbs needed to be pulled, had one float that would not cooperate.

My Number one reason for Down time On my GL1100 is Carbs.

My GL1200 No Down Time, BUT!! Bringing the GL1200 out of winter Hibernation is a couple day process, do get carbs working properly again, mainly ride it back into a good state of running, so I can jump on and Go.

It will be interesting to see how the single Carb does on my winter shutdown/restart routine.
Second

I hope the Single is going to be way more simple to work on, we will see.

Guys, I got a 34Pict3 single barrel carb. There's any adapter to fit this carb on a C13-3244 manifold?
