With but a basket and a baggie of even smaller parts and screws provided by the previous owner, rebuilding these carbs is about to get started. Wish me luck!

Good Luck.  I'm sure you will do fine.  Are you going to soda blast them?

Thanks, edhaeuser!
I have already soda blasted these and cleaned out most of the gunk buildup in the float bowls. There's actually some soda residue on these carb parts so I'll probably dunk them in some Pine Sol, which I read is the thing to do.

I'm off to Home Depot to look for one measly 4x10 pan screw that's missing. I hope I can find it. I love the Home Depot. Any excuse to go there is good enough for me. I also like to think that trips there help to motivate me and give me ideas about a bunch of things I probably don't need. Save me.

Home Depot has metric hardware too? Will have to check it out. I've always read people go to Ace Hardware or the online McMaster site (I can't recall exactly) for metric stuff...

On the carb cleaning, soda blasting is great, but I'd say double check the pinsol dip if you're trying to preserve the factory finish on the outside. On mine, I went with ultrasonic cleaning just because I had access to a USCleaner, and it they came out great with the finish intact.

Yep. They got em at Burbank, CA. The head isn't quite the same but hey, a screw is a screw ("that's what she said").

Yes kudos for ACE hardware. The one buy my house in Roseville has the best selection of nuts, bolts and all kinds of goodies.

It's happening...

Float pivot pin on #4 was a real bugger. Followed some of tricks found here on sohc4 and used a combo of a Harbor Freight spring-loaded center punch and a 1/32" nail punch to drive the pin out far enough on the other end to twist it out with some pliers. Jets are looking ok aside from some gooey black gunk but plans to leave that soaking in some Berryman B-12 CHEMTOOL to clean them up and replace the seals...

Progress?

Thank you thank you!
Still lots to do; so little time/money.
Hope I don't disappoint. Thanks for tuning in.
Carbs are taking me a while so it'll be some time before I report again, probably. Thing is I'm not sure how far I need to go with the scrubbing/cleaning of the carbs and their components so in doing my darnedest. One whiff of my living room can attest to the amount of solvent I'm using though. Catchin the vapors.

The on/off again carbs saga continues. Overlooked the "emulsifier tubes". Used a center punch to drive them out and a thin gauge guitar string to poke/clean the tiny holes.

Good going using Honda carb kit, I used a cheap aftermarket when I rebuilt the carbs on my 500, within a month the o-rings began deteriorating. I removed one of the bowls, had a plugged pilot jet and noticed the o-rings in bad shape. They cost more, but well worth it.

Thanks, leetmeatcr and rtbmrgl. Exciting and fun is what's it's all about, right?

As for common seals and other bits and things, I've tried not to stray too far from buying Honda. Partzilla.com has been my go-to lately.
I'm relying that my carbs, according to the PO, are in OK condition so I've done my due diligence in cleaning them as best I can. So as the carb saga continues, my next purchase for these things is to replace the spring clips for the hoses:
95002-02070 CLIP, TUBE (B7)
95002-02100 CLIP, TUBE (B10)
I realize these don't necessarily have to be the Honda ones so I'm stopping into my local Napa Auto Parts to see if they might have something comparable.

Also thinking to go with the Uni Pod Kit. Hope it fits and works. Any other recommends out there? I like the look of the K&N pods I can't reason with the cost.

Fabricated an under seat electrical tray today out of .118" styrene:

It's recessed 1" (same thickness as the frame). Probably not deep enough for stuff but I'll rest the stone buck back into the cavity of the tray so when I lay and set in place the styrene seat pan above it, I can run a heat gun over the area to create a kind of dome to allow a little more clearance for electrical stuff and wiring. Easier said than done.

I would like to know more about this process.  That electrical tray is awesome!

I too, would like to know what exactly is taking place there. Its super nice looking and I assume you could use the same process to re-create the stock airbox cover that always seems to be missing.

The process is vacuum formed plastics. Create a mold, then use plastic sheets that are pre-heated, and draped over a mold. The vacuum case pulls the pressure out and forces the plastic sheet into a cured, new shape. Its easy to do, and very versatile.

Taking cues from Bru-Tom and some others of you... I welded on some turn signal tabs right up against the frame hoop cut-off openings. May need to tweak it a bit to straighten it out but I'm pretty pleased with knocking this off my list. These aren't the greatest in turn signals. DOT-approval leaves little option for good looks.

Finally took a plunge and got some parts powder coated a matte black. Quite pleased with the results. If you're in LA, I recommend Tortoise Industries. They came highly recommended and I see why.

Now it's time to get this stuff mounted!

Sticking to the theme of "slow as it goes", here we go with the reverse process of pulling out the rear shock bushings and getting these pressed back in via the "outside going in" - a technique not forgotten from some post here because these holes are slightly tapered...
