Any suggestions on where I might find replacement Keihin press in low jet emulsifying tubes for my 79' CX500? 045 is what I'm in need of - 2 ea. I have severely damaged one of them on extraction. Or, is it possible to thread the seat in the carb body for the newer screw in type? Any suggestions/direction would be much appreciated! Thank you.

I don't have an answer for you but I'm sure someone will be along shortly who does have one.
Welcome to the forum. Please add your location and your bike's model and model year to your profile so that you don't have to remember to tell us every time and we don't have to keep asking when you forget (see Forum Settings link in my signature).
And welcome to the world of antique vehicle ownership (they own us, not the other way around). Your bike is about 4 decades old and may or may not have had all of the maintenance necessary to keep it safe & reliable so it is highly recommended to download the Factory Shop Manual for your model (available through the CX Wiki - link in my signature) and go through all of the service procedures, regardless of whether your bike has reached the specified mileage.
Note that while aftermarket shop manuals are pretty much necessary for people without factory training to work on a lot of makes & models of bike the FSMs for the CX/GL500/650 family of bikes are so well written & laid out that the FSM is really the only book you need and and even the best aftermarket books are secondary references at best.
I also recommend looking on all rubber parts with suspicion because rubber does not age gracefully. Check the date codes on your tires and replace them if they are over 5 years old no matter how good they look & feel (old rubber simply cannot flow around the irregularities in the asphalt well enough to grip, especially if it is cool or wet). The original rubber brake lines should be replaced every 2 or 3 fluid changes (= 5 or 6 years) so if your bike still has them I recommend shopping for modern stainless braided ones (they last practically forever and double the life of the fluid). And don't forget things like the rad hoses and the boot between the engine and swingarm (they can crack on the bottom where you don't see it).

Where is the damage? If it's only on the upper end where the extractor grabs, it might be OK. The small end and the holes in the shank do all the work.
It's too late for these ones but for next time a lot of people have reported success tapping the wide hole (where you would engage the easy out) to accept a small bolt and using a bolt and nut to jack them out.
I'll try to look in my stash. I might have a spare.
Don't thank me yet. I still need to remember when I'm in the garage.

Someone posted a source for these a year or three ago. I haven't had success finding the thread. Perhaps someone else tagged the post?

Not sure if these would work or are still available. https://www.cb-four.com/cgi-bin/shop/__Jet-Slow--45-carburetor-Honda-CX500__19-071-19_16.01.08.html
That's exactly what I'm needing and yes, they still had them! Thank you Mike and thank you Randall for your offer to scrounge around in the garage - I'll let you know if there's any issue receiving them from CB-Four - but the order did go through! This is a great forum and I thoroughly appreciate everyone's help and input!
