80 GS450L Carb Mixture Screws...Can't Buy?

[exbellicus]

Went to Suzuki dealer today, they say there's no part orderable to replace the fuel/air mixture screw. They say its not in the fiche. I need two of them, because mine won't come out and I think I am going to have to drill them out. Any thoughts? I thought it was #50 on the parts shark fiche here, but it's a different screw.

Usually you can get them in the carb rebuild kits by K & L
Check ebay or any of the online vendors

Cut a new slot with a Dremmel and heat it up with a torch. It'll come out and you should be able reuse them. (Strip the carbs first)

A friend suggested I can blow it out with an air compressor from the other side. Going to give that a shot in the morning

Blow out a screw with air? I'd like to see that

Had a similar issue when I rebuilt the carbs on mine. The fiche on bike bandit doesn't show the mixture screw, but when I went to the dealership it showed it on their fiche. Thankfully Jethro here saved me by sending me one. Had to send two since the first was lost by the USPS. I'd say go back to the dealership and see if they'll let you see what is on the screen. Otherwise ask here or search ebay for a set of parts carbs.

Well this is the mixture screw, and I'm sure it is already past the threads it is just stuck in there, I think it might just be the seal is making a suction.

The GS450 uses BS34 carbs like the GS1000 right?

You should be able to use 2 of the 80 GS1000L carb kits from Z1..
They come with new pilot screws. Just re-use your old jets as I doubt the GS1000 set would be the same.

Robert Barr also has an O ring kit for the 450's

No luck on finding a carb kit

I've got an o-ring kit from robert. Carbs have already been dipped and all o-rings have been replaced besides these.

Not sure what you mean by "already past the threads" So, you unscrewed it all the way out, however, it still won't come out of the tunnel ? If you can unscrew it enough to clear the threads, perhaps you can grab it with a small pair of needle nose pliers. Honestly, it shouldn't be that difficult to get it out if it's unscrewed. All the ones I've done just fall out.

There shouldn't be any suction on this screw.

Yea Larry I've turned and turned them both, tried pulling out with pliers but the hole is too tight to get anything in there. I'm thinking I drill a tiny hole in the screw from the top and pull it straight out, so it would be reusable.

Weird....are they BS34 carbs ?

If you do try a drill, you're going to need a reverse cut bit, also known as a left-handed bit. They are designed to cut as the drill turns left. Otherwise, you're going to drill it back down into the tunnel.

Let me think on this one for a minute.......

EDIT:: Can you post a picture or two.
