    rubber plug or not?

    Is there a way to tell if the gs1100 carbs I buy to clean in my ultrasonic cleaner came with the rubber plug under the pilot or not? I don't trust people that the plug may have been removed. I wouldn't want to sell someone a set that should have had the plugs. They'll never get them to run right.

    You can have a look at the parts fiche. I use our local dealer : http://www.sturgessonline.com/fiche_select.asp

        nothing wrong with using our local guys to see the parts, but what I find is there is never any pricing on there, so you really have no idea what it's going to cost you.....

        I like to use these guys



        they at least show a price

          If your float bowls have a little shelf for the rubber plug to rest on...
          it came with the plugs. Easy.

            The fiche only shows the carb with the plug. There was another carb used that didn't use a plug. It had passages in the carb body that negated the need for a plug. I want to know how to tell the difference just by looking at the carbs of which I have about 20.

            If you have some spare 1100 carbs you will see that most have a hole under the pilot that goes right thru into the carb body. Can anyone remember if that carb came with a plug?

              All my float bowls have that shelf.

                Did you check this fiche? Item 39. These Are CV34 carbs for a '82 GS1100E.

                  Ok, there were 2 types of carbs used on the 1100. One had a hole under the pilot that went thru the body of the carb into the venturi. In the other type, the hole didn't go all the way thru. Suzuki made some design changes. My feeling is that if the hole under the pilot goes all the way thru the carb body then that carb has the plug.

                  Can anyone look at a spare carb & confirm?

                    I's still hoping someone can look at a 1100 carb & tell me if their carb has a rubber plug & the hole thru the carb body?

                      Looking though the parts fishe all the GS1100E carbs use the plug. In fact, I'm unaware of any GS bike with CV carbs that don't have the plugs.

                      I believe you are right that there must be that cross-drilled passage to transfer fuel over to the pilot circuit if the plug is in place. What specific carbs do you have that don't have these passages? I've never seen one before.

                        Here's a pic of what I'm talking about. Note that there is a little brass plug at the base of the pilot jet tower & no hole below it in the carb body. My belief is that this type takes no rubber plug. Maybe this is for Canadian carbs only? Although, most of my other carbs do run the rubber plug & don't have this brass plug.

                          Sorry, I don't see the brass plug you are talking about, but I agree with the others, they ALL came with rubber plugs from the factory.

                          If one of yours was missing a plug, it was wrong.

                          Look at the top of the pilot tower and the main tower. There should be a diagonal passage between them. That is where the pilot draws its fuel from when the rubber plug is installed. Without the rubber plug, the needle jet can draw through that diagonal passage as well as the main jet. At full throttle, even more fuel can go through there, as well as the main jet, so the bike would be RIDICULOUSLY over-jetted.

                          You can see the passage in this cut-away. The main jet is #3, the rubber plug is to the left of it. The diagonal passage is above and between them.

                            EDIT: Steve posted while I was typing.


                            The cross-drilled passage that allows fuel to transfer from the main jet passage over to the pilot jet is near the entrance of the passage, not down stream of the pilot jet. What good would the pilot jet do if the fuel wasn't even flowing though it? Honestly man, I think you are off track on this whole pilot jet plug business. All GS CV carbs require the plugs.
