Runs well but plugs are sooty black. Why? (GS1000 G)

[Vloukole]

I bought all new jets. Main, pilot and air jets.

 

[Vloukole]

Its a 1981 or 82. Gs1000 G

 

[Vloukole]

What manual do you have? Will the right size jets in the wrong carb bodies make it run bad?

 

[GSX1000E]

You are getting confused Chuck. He has 34CV carbs and his stock jetting was: 115 mains, 40 pilot, 5D57-3 jet needle, X-8 needle jet with 160 pilot air jets.

 

[Vloukole]

Yes that is my specs GSX1000E. How do I know that I have the correct carb bodies and not another bike's carbs?

 

[chuck hahn]

I deleted the posts...didnt realise he had CV carbs and I didnt go back thru the thread to find out...my bad.

 

[chuck hahn]

Folks really need to fill out the signatures ..makes keeping information much easier to find and fresh.

Beats me, I just use whatever I have laying around and MAKE them work on the bike that I am going to be using them on. A few of my bikes might have the stock carb bodies on them. IDK

 

[Vloukole]

Atleast you get them to work! Does anybody have a picture of the stock carbs for a 1981 GS1000 G?

 

[GSX1000E]

Probably not what you need but, here is the easiest one for me to get a pic of and these are not the stock carbs (no idea what I got them from) but they did work well enough
to fire up this bike that has not ran in a little over 26 years and take it for a test ride.



A random pic from another set of 34CV carbs. that might even be those carbs.




Perhaps some of the dozens of other owners of these model bikes on this forum could take some pic's for you as well.

 

[Vloukole]

Those are the carbs that I have. You say they are not stock??

 

[chuck hahn]

Look on the carb bodies for any numbers stamped or molded on them. That would be a model code and someone here will know what they are. Buddy of mine down in texas had an actual Suzuki code book with all that kind of info. Dont know if he still does or not.

 

[Vloukole]

I looked at the choke cable and it is tight. How do I loosen it because it is totally screwed in at the carbs?

 

[chuck hahn]

If its a pull knob in the center of the steering head you loosen the nut there and turn the assembly one way or the other to get slack.

 

[Vloukole]

Gave it more slack. The choke did close fully. Why do you think the carbs need less fuel now(smaller jets) because the only thing that is not stock is the 4 into 1 exhuast?

 

[Vloukole]

Do you think I can order jets 2 sizes smaller? 110 main and 35 pilot??

 

[chuck hahn]

Got any numbers on the side of any of the carb bodies??? You can order smaller..didnt I post the jet chart to this thread somewhere??? You gotta get the fuel supply slowed down for sure. Or maybe use a bigger air jet ( lower left one in the front of the carb throats ) to get more air into the mixture coming up out of the bowls. And thruthfully, it may boil down to a mixture of both smaller jets AND a bigger air jet up front.

If i didnt post the chart..here it is again..

[Vloukole]

No I could not see any numbers on the side carbs.

 

[Vloukole]

Do you think I can go 2 sizes smaller?

 

[GSX1000E]

How well packed is your muffler? If it is good shape and not blown out, return everything to stock in the carbs except the main jets. Make those 122.5's or 125's.
Make adjustments from there.
