Picked up 2 1982 GS1100's. Running issues

[Rob S.]

To run with pods you need to install a stage 3 jet kit. Simple as that.

Or do this to your pods:

(It was a temporary fix, until I got the stage 3 kit.).

Ha nice Rob.

Well right now I need to get all 4 cylinders firing first and im stumped at the moment.

I pulled the carbs off, all 4 carbs still look clean, jets are clear and they all appear to be in sync with each other. Passage ways are clear, Slides are moving. and all 4 carbs had fuel in there bowls.
the #1 and #1 cylinder both were getting spark.

What else do I check now?

[irishluck]

Here's a pic of the carbs, They look perfectly synced.

Now I will say this. on the #2 card I think? there is a hose that comes off the carb that I know will hook up to the fuel tank. Assuming that this is back pressure to help fuel being pushed through the carb.

But I am using an auxiliary tank at the moment and my fuel tank is off.
Could this be the issue?

The port on #2 is used as a vacuum port to open the vacuum operated petcock. When using an aux fuel tan, you should plug that port.

could that cause those 2 carbs to not fire?

[JTGS850GL]

No. It would cause #2 to run very lean. There's very little in common between cylinders 1 and 2 that would cause both to not fire. My guess is you have two different things going on here. Fix the known problem and plug up that vacuum line. Then see what you have after that.

[irishluck]

Thanks for the advice Ray, Ill give that a try and report back with my findings!

[irishluck]

I've got 4 cylinders firing!

I found a missing screw out of the choke rail for carb #2(which you can see in the pic I posted). I took a set screw from the 2nd gs1100 and put in on, installed everything back on and got 3 cylinders firing.
I then plugged the hose to the petcock that is on carb #2 and the 4th cylinder fired. Now im not sure if me plugging that hose made cylinder 1 fire or if the missing set screw from carb #2 was the cause.

She sounds good!

I think there is some minor adjustments I still need though cause there is a slight backfire going on. Every couple of seconds it pops.
Smoked like crazy too at first cause I had to use a little tranny fluid to put around the rubber hoses to slight the carb onto it.

[JTGS850GL]

Time to do a good vacuum sync. and a valve adjustment. Should purr smooth after that.

[irishluck]

Ill need to get the sync gauge to do that. The one tool ive been needing to get but haven't yet.
And the valve adjustment will be something new, ive never done one before...

Also the exhaust is popping when at idle. Isn't that an indication of running lean? Should I adjust the mixing screw?

[JTGS850GL]

Get the valves adjusted before you go any further. Tight valves will have a number of different effects. Any carb sync must be done after the valves are adjusted as well. Where are you located? Maybe a forum member will have a gauge set you can use.

[irishluck]

Is there a guide on how to do a valve adjustment? Cause I dont see it anywhere in my service manual unless I didnt look in the right place

UPDATE:

I found it in my manual. will update after i check them all out.

[irishluck]

I'm going to have to say that there most likely in spec.

The book says that the exhaust and intake need to be between 0.03-0.08mm
The smallest feeler gauge I have is 0.038mm.

Only one valve let me put the gauge through but barely. All the others wouldn't let me put it through.
Unless I really need to go get a feeler gauge rated at 0.03mm, I think these are all within spec, what do you think?

Also, is it okay for me to just use gasket sealer to seal the valve cover back on? My gasket broke when I took the cover off.

All OUT OF SPEC is more like it. You need thinner shims.

Negative on the gasket sealer too. Get a new OEM Suzuki gasket.
