SlyDog's Cafe' Project 2 - '80 GL1100 (SDC)

[Jack the Dwarf]

I like what you are doing... But i still dint understand the tempgauge problem..... The stock tempsensor for the gauge is on the right side of the engine, somewhere behind the carbs (really tricky to get to it, believe me i did it....) and from there comes one wire (ground) to run the temp gauge..... I think i am not smart enough at 4 in te morning to understand the Problem but you will make it right!
The magnets where the reason why i chose the daytona speedo... It comes with an active sensor, so it takes the speed from the bolts itself....

[SlyDogJeff77]

Oh the temp sensor ISN'T a problem!! I think its fine the way it is! I'm just going the extra mile! I already have the one you mentioned hooked up. Now I'm hooking up the 2nd one in the diagram.
There are 2!!

[SlyDogJeff77]

Oooooo look what I just found!

When I did mine I took one of those really strong magnets from a necklace and stuck it in a brake rotor bolt. Worked great!

[SlyDogJeff77]

Oh crap!! I just realized something!!

Help! Question! Is the outer axle spacer for the '80 gl1100 different than the one shown in this picture!?!?!?

I ordered one and it came in the mail. I got what I ordered but it wasn't what is shown in this pic! I thought I had the wrong part number!! But I just double checked and this is the right part number!! It looks like the outer axle spacer for the '80 is more like a flat washer!
The '82 is like this pic! It's wider and has a tapered / beveled edged??
Am I right?!?!

Here is the part number I ordered
42312-463-000

Here is what I see in the pic below
42312-MB9-000

HELP!!

She's not starting..

Sounds like timing might be off. Check to make sure all spark plug wires are on the correct plug. Did you check static timing?

[Rugis]

I will not pretend to be any kind of expert on anything But this is the advice I have gotten in similar situations. You need three things to get her going; gas, compression and spark. You have rebuilt your carbs, but do you know that all passages are clear? Are the float bowls filling up, and at what rate. I recently did a rebuild of a rack of carbs, they were sparkly clean but still wouldn’t cooperate. I ended up spending a small fortune on a ultrasonic cleaner, and that actually did the trick!
When you are confident the engine gets gas, you check compression. But you probably already did that multiple times, so I will assume compression is good. But did you check the valve clearences again? You can test if valves do open and close fully by using a leakdown compressiontester. This will also give you info on the cylinders that a normal compressiontest would miss.
The last thing is spark. And the bike is firing every now and then, so we know you have spark, but when is it sparking. Have you checked timing? Do you use the original points, or electronic ignition? Check that cables from the coils are routed to the right cylinders, and check that coils are wired correctly with the ignition.
If you already did all of this, send in the experts

[SlyDogJeff77]

Fuel, CHECK!
I made sure the lines were clean and the fuel pump is working.
Fuel is getting all the way up to the engine.

Carbs, CHECK!
I made sure all the passages were 100% before they went back into the bike.
This is the 3rd time I have rebuilt GL1100 carbs. I DO NOT mess around with my carbs anymore!

Spark, CHECK!
New plugs, new wires, confirmed they are all going to the proper cylinder!
Coils look good and since I'm getting smoke, spits, sputters and backfires I think its safe to presume they are working.

I think it has to be timing or valves. So since I'm pretty sure I followed the manual on installing the belts TO THE LETTER, and I DIDN'T check the valve height/spacing.

Need I say more??!!

Someone point me in the right direction?
I think tonight I'll RTFM!!
But off the top of my head I have to take the valve covers off and get one of those valve guide things?? It's like a pocket knife with all different thicknesses??

And then I....... Do... Something... With it...

Here is what has led me up to this conclusion.
I took the air filter off and look in the plenum while trying to start it.
I saw fuel coming into the plenum.
I don't think it should be doing that...

[Rugis]

Again, no expert talking.. But I guess gas in the plenum could mean that gas is pushed back through the carbs because of not fully shut intake valves. I could also indicate a faulty plenum gasket, but I guess you would like to check the valve clearance first, considering all the work you have done with the carbs.

That being said. Rebuilding the carbs three times is not a guarantee that everything is 100%. If there is a problem with a clogged passage, I mean really clogged, chances are that if you didn't get it the first time, you didn't get it the third time either. I hate carb problems, because you never know what it might be. I have seriously considered getting a second carb rack just for reference when looking for problems. Switching back and fourth to see if the carbs are in fact at fault.

[SlyDogJeff77]

No no. I didn't rebuild THESE carbs three times. These carbs are new to me. And they are spotless!
This is the third set of carbs I have rebuilt. I know what I'm doing.

Let me look into the valves first and get back to you.

[ericheath]

If you have moisture in the plenum, you have to pull them off and fix it. Pretty good fire danger. I have pulled them off enough to know that you have to pressure test them on the bench first.

[SlyDogJeff77]

I think i found the problem. I set the valve set screws and then I went to check the spark plug gaps just in case. I found that plug #4 wasn't firing. The other 4 were starting to blacken but #4 was still spotlessly clean.
So.... Now I'm thinking it's the coil or the wire.. either way.. I want to replacement both.

[ericheath]

I just went through the same thing with mine. Coils checked good with ohm readings. I now use 1500 coils. They are 3.2 ohms+-. Cheap and plentiful. You need to find out why your plenum is wet. Even if you get it going, you're going to be rich.

[SlyDogJeff77]

WAIT CRAP!!! I litterally just hit purchase now on a full set of new replacement OEM coils and wires!!
You're saying I can upgrade to higher ohms for less?!
where?!
how!?
link?!
quick please.
