When the head breaks off like that it means the threads are frozen in place due to corrosion.
You will need to pull them off to get it loose. Sometimes you can cut a notch in it to use a screwdriver and back it out. But usually it's more involved than that. Sonic cleaning, drilling, ezout, or drill and tap the threads to clean out the old threads. Then replace the needles.
It sounds like the carbs could use a good cleaning anyway if you are already having stuck needles.

Crap. I hate working on the carbs. It's so..... involved. Last time I rebuilt the carbs I paid a guy to do it.
Besides, I was hoping to get some more riding in until the winter. If I take the carbs apart the whole thing won't be running until it starts snowing (and in SLC, when it snows, it snows hard).

Well, here goes guys! I don't usually do this, but I do rebuild carbs. In fact if you look down in my signature I have a link to the book I wrote on the subject. If you want them done for you I could do them and have them back to you in a few days tops. When they are returned they will already be balanced and road tested. That way all you need to do is install them and go ride. If you sent them tomorrow, you could have them back by Tuesday or Wednesday.
The cost for a totally rebuilt and balanced set is $265. That includes all new parts internally as well as any small items that may need replaced. I'm sure someone will jump in and vouch for me here, but they come back to you all polished up as well.

By the way, put your bike in your signature so we all know what your working on. It helps us all when it comes to helping you.

Its like buying a brand new set of carbs. I wonder what Honda would charge for a BRAND NEW set of Keihins?
Nice carbs Larry! I might take you up on the offer.
I actually have the carbs from the parts bike (1980 CX500). I know that with the bike being so old new "major" parts have been discontinued, so I was thinking of combining the two (along with as many new parts as possible) for a "new" complete set.
What's strange is that on the right side, a flange of the metal plate connecting the two carbs together, is snapped off. For the life of me I can't remember anything happening, and I haven't dropped it either. Maybe I was just completely clueless to it being damaged for years.

The parts carbs are labeled 25ACSE7 with a VB above it. The running carbs are labeled 25ABRHt with a VB above it. So they're not the same, but then again, the parts carbs would be matching up with their own original engine (I moved the parts engine to the bike years ago). I was actually thinking of shipping you both so you could use the non-busted parts from the parts carbs (such as the plate with the flange around the pilot screws; I know that's interchangeable). Anything else that could be replaced new would be a better option, of course.
I say let's do it! I'll let you know when I have the old carbs out, and I'll probably need some help putting them back in, but for $265 it's the best option.
Hopefully the new carbs will make the engine look bad!
I can vouche indirectly for you Larry from up here in Canada. I've since sold my GL but I went to a buddies last week about 1/2 hour away. I took a look at his old CX and saw the polished carbs....and told him that they look like Larry's carb rebuilds. Of course that was exactly what they were. He said he put them on and the bike sparked up and never run better, totally losing the mild mid rpm bog he was experiencing.
Sorry about the delay. I'm pretty sure I don't have a vacuum operated petcock, just a normal on/off/reserve petcock (unless there's more to it than I realize).

That's good Karma, because I already have the carbs done. I made a choice from re reading the post here and went with the set without the vacuum fitting. They run great now. I'll ship them out to you tomorrow morning. Thanks for letting me do the job for you. I think you'll like the outcome.
