I recently purchased a CBX-C basket case. Ultimately wanting a CBX-Z. I’ll see if I can post a picture.

Welcome! And congrats, I guess. What state/condition is the engine in? Did you supposedly get ALL parts and hardware that were taken off? If you are able/capable of doing all work necessary, these can be a quite satisfying project when bought for a good price in this condition. But if you have to farm even some of it out, it can get frustrating and expensive. But not much different than many other bikes of this era in this condition. Except the carbs and engine!!

Please post some more pics and describe more of what you have there. Search up many topics here, but don't hesitate to ask away!

The first thing I did was reassemble it just to familiarize myself with how/where everything goes. Everything is present and accounted for and some duplicate parts like chain guard, foot pegs, turn signals and a few earlier CBX parts mixed. The engine was removed but still assembled when I got it. The PO said the stator was bad. There is a NOS Honda stator included in the parts that came with the bike. Looks like a typical took it apart and never got back to it. I will go through the top end and carbs, replace the stator and then get it started and see what I have. I’ve been and still am a master ASE technician for over 35 years, so I’m reasonably confident I can handle the project. This will be my first CBX, but I’ve done a fair amount of M/C repairs. I’m also pretty heavy into K0,K1 Goldwings right now. It’s all nuts and bolts, factory manual and some research. I’d be interested in experienced suggestions as to what pitfalls to avoid. I’ll post some more pics when I get back home.

FWIW, and I know right now you don't think this, the carbs will be your biggest challenge. Keep us posted and good luck!

What Dave said! The bike looks like it was stored well, so that will save you a lot of that troublesome nit pick work and the body panels look good too. Plenty of advice and a very comprehensive tech section broken down per category in the sub forums, everything you need if you run into questions. Good luck on your project and keep us posted on your progress!

I appreciate the heads up on the carbs. That’s exactly the experienced input I’m looking for. I had a learning curve on the GL1000 carbs. Had the first set out a couple of times before they were right. I’m not easily frustrated. If I have to do things a couple time to get it right I’m willing to do it for the education. No one is expert the first time and that’s ok. Once I get going I’m sure I’ll have more questions than answers.

From your friendly CBX carb "guru":

Replace or drill the pilot jets to #38. This will provide easier starting and overall performance.

Drill/tap/extract the plug by the mixture screw in order to properly clean this circuit. Reinstall afterwards.

Discard the filter screens attached to the float seats and fabricate/install an inline filter where the AFV is now (eliminate that too).
You won't know when they're clogged, not easily serviced, not used on other Honda models.
This also means that you'll need to get in the habit of turning the petcock OFF whenever the motor isn't running or about to run.

Bench sync the carbs.

Mixture screws at 1 and 3/4 turns out.

Replace the connector boots.

Wet-test prior to reinstallation.

Buy what you need from KMCarburetor.com

Thanks for those tips. Makes perfect sense. The cutaway views make the process crystal clear. The dreaded idle circuits are always the hardest to clean. I will be removing those plugs and will implement the rest of the advice.
