IT'S A DRY HEAT! 1979 CBX restoration adventure

Those are Dyno-Jet needles. I can't tell if you still have the Keihin main jets or not. If you are using the stock airbox, you'll be better off going back to the stock needles and jets, then tweak from there.

Be very careful to check the brass standpipes for cracks - I'll be shocked if you don't find one or two.

Get a comprehensive carb rebuild kit from one of the established vendors - JR here, Randakk are the two I'd look at. They each have all the rubber parts and other goodies you'll need.

Six, we may have your carb body for you, I just need to get to the shop and look. Have you made headway with that or the special tools? I can spare the tools for a short spell when you're ready for them too.

Very generous, Nils.

Those are Dynojet jets. They're taller and have a more shallow bevel (funnel ?) than Keihin jets.
Dynojet claims they flow better but I don't buy it. Jet numbers and actual sizes do not correspond
with Keihin.

Dave, I found what might be the stock needles and jets. I would like to keep the individual K&N filters I've had on it, but I do think the needles, as you've stated, and the jets are dynojet. I'll get them all out one day and take pictures to be sure.

Thanks for the reminder about the standpipes. I need to test those. Is there a specific liquid that won't evaporate too quickly that works best? I think I've heard kerosine used.

Nils, wow, thank you for checking if you have a carb body AND are willing to loan the tools. I'm going to make my own out of some sockets. It would probably be cheaper that way anyway instead of spending gas money or postage. I am interested in a carb body though, I think it's the #1. I don't know how it ever worked on the bike, but I know I didn't break it. If you do have one, just let me know and thanks again.

Oh, and Dave, who is JR for the carb kit?

[NobleHops]

Six, send me a photo of the carb body you need please - nils.menten@gmail.com

Also, WRT the retainers, it’s no big thing to put them in a flat rate box up to you - just let me know when you have your parts in hand and are ready to do the bearing projects so I can limit how long they’re gone. I also have a tool that makes the removal of the problematic lower steering bearing race a cinch.

Drop me an email with your full contact info and the phot of the bad carb body and we’ll go from there.

Do not fail to drill out the stakes, and do your best to remove any drilling swarf with a shop vac before you attempt to move the retainers.

Nils, I will get the carb pic tomorrow. I worked on the wheel bearings today. What a freaking adventure. Only one thing was messed up and it was even mentioned in one of the links above. The threads on a bearing retainer are messed up. It was all good until it was half way out. The bad threads are on the bottom of the retainer. I'm still not sure what caused it, but I made a video of the process. I will need a new retainer though for the rear wheel.

The swarf from drilling can do that if it isn't removed, and that's problematic at best. You DID drill out the stakes, right? If you got these out without damaging the threads in the wheel, then that's victory. Reuse of these isn't advisable in my book anyway.

Your window to get a carb body from me is going to close temporarily in a few days, as I will be traveling for a month at the end of the week.

[sixpiny0da]

I did drill them out and this was the only one that had a problem. And it only had a problem halfway through. The top two threads on the wheel are damaged, but I'm not worried about it. I'm going to get new retainers since I found them online. And no worries on the carb body. This project will take me a while. All my money is going to an attorney at the moment to defend ourselves against my wife's ex. He's straight out of a movie. If you get this, have a great trip and we can talk about the carb some other time.
