    Default GS750T carb uh oh!

    Well, I had cleaned and installed carb kits in my 1982 GS750T. I was able to get the bike running, it just took 20+ minutes to get “warmed up”, each time I started it. I had replaced everything but the pilot jets. They were plugged with a metal plug so I felt that they shouldn’t be tampered with. But since my bike’s performance issue may be linked to the pilot jets, I removed the metal plugs and changed out the jets. Very, very unfortunate for me, one of the jets was stuck! I ended up having to use a screw extractor to get the stuck jet out. That turned out to be a very, very bad decision! The screw extractor snapped off level with the pilot jet, down in the pilot jet tube! Terrible!
    I have tried to drill it out with no success, due to the hard metal that the screw extractor is made of. Even if I were able to get it out somehow, I have probably screwed up the pilot jet shaft by now.
    Is my best option, to try to find another carb?
    If so, is there anywhere to get just one single stock carb for my bike?
    Would some other set of carbs (other than the Stock ones) for work on my bike?
    Thanks again GS Resources.

    There are 2 great CV carb cleaning/rebuilding tutorials on BikeCliffs Website, right column, top of the list. I wish you had read those before starting working on your carbs. Consensus on carb “kits” is not favorable. Replacing the orings with a set available from cycleorings.com is recommend. If float needle valves and seats are not sealing, those could be replaced as well. But typically the other things you would get in a “kit “ aren’t going to help you. All that said, I’m not sure where to tell you to go next. I’m sure others with more carb repair experience will chime in. Hang in there. You’re in the right place.

    The pilot jets are accessed by taking off the bowls. They are capped with a rubber plug next to the main jet. I think you are talking about the enricher screws (Probably wrong term). At any rate, your problem now is getting the stuff out of it. the threads may or may not be damaged. I'll see if I can search cup some help. I'm assuming your model has CV carbs like mine.

    Thanks. I actually did get the set of O-rings from that site. They solved my leaking problem perfectly!
    My bike was running good after my carb cleaning, but only after 20 or more minutes of babysitting each time I started it up. That’s really the main reason that I was going to clean or change the pilot jets. Then 3 of the 4 jets came out great...but that one! There is always one!!!
    Anyway, I’m stuck now. Any good thoughts/help/ideas is appreciated. Thanks

    Post 7 in this linked thread. There is a picture somewhere but I can't find it. Maybe someone else can. Sorry if I'm misunderstanding your dilemma.

    Actually, that may be for a VM carb but the idea is similar.

    Post 3 by Steve. See how slots have been cut in the towers to get to the recessed screws. Are these the screws we are talking about? It may not help with the extractor
