Replacement Rim Options
« on: September 03, 2024, 03:23:45 PM »
Just for giggles I’ve done a little shopping around for new rims and spokes*… and boy was I off on my guesstimate of what such things cost…

The cheapie “Rising Sun” brand rims that 4into1 sells have a pretty attractive price compared to the real manufacturers.  Does anyone here have any experience with them?

Got them and they were trash, the weld seam is so big you could see it from a decent distance away and they would not true up at all.  Went with DID from Yamiya and it was night and day.  Its a waste of money in my opinion but others have had some success.

Exactly the honest feedback I was looking for. Thanks

They’re high. I like Stainless Steel spokes and nipples and the large diameter ones for the rear..Especially if you go with a fat sticky tire and a big bore…

I once bought a set of the Rising Sun rims and immediately returned them because they were junk, in my opinion.  DID rims are high quality and I recommend them.

I mostly use rims and spokes from vintagecb750.com. Their rim and spoke prices are reasonable.

I went with Buchanan. A great option over NOS. Obviously not for someone looking for a correct restoration. However maintenance issue is greatly reduced.

I am restoring my CB350F and the spokes are rather "dirty" looking.  In my search for what was original, there are so many pictures, and hard to say what was original... when you say correct restoration, what were the original spokes... cad plated, stainless or chrome?  I'm leaning towards stainless, chrome doesn't look right to me (too bright).

I've got other questions on the finish of aluminum parts, is there a "restoration guide" somewhere... I've searched the FAQ.  TIA.

The spokes were zinc plated and the nipples were yellow zinc.  Zinc plating is a sacrificial coating in that it is meant to corrode to protect the steel underneath it.  Thats exactly what it does over time.  Unless you are restoring a sandcast, stainless spokes and nipples are completely acceptable as replacements that will last much longer (forever) than the originals. 

On CB750s Aluminum engine covers, brake plates, wheel hubs and fork legs were brushed finished and clearcoated.  Master cylinders were anodized black.  Brake calipers were painted either silver or black.  Aluminum triple trees were painted black.  Honda didn't leave anything raw aluminum.  It was either clear coated, painted or anodized.  In the real world many of these finishes won't last over time.  Moisture gets under the clearcoat and starts to corrode the aluminum.  Black anodizing fades to purple in the sun.  The painted parts hold up pretty well but over time it can flake off in small sections.  I usually just polish or brush finish engine covers etc with no clearcoat.  They are much easier to keep nice with a little polish or a maroon scotch brite pad for brushing.

Forks are tough. I cleaned mine up, lightly polished them and clear coated. Over time road stuff damages the clear and corrosion returns, I suppose I'll re do the lowers some day.

Thanks, guys.. this is very helpful...... it's a matter of what looks right to me, and at the same time trying to keep original... so all this goes round and round in my head.

Spokes - I did lean toward all stainless and agree about the zinc dichromate yellow..... regular zinc won't cut it long term.  My rims are in decent shape so I'll clean up the chrome....

Engine covers - I am going to polish the clutch and left side cover, including the generator cover, then I'm thinking a 2K clear should be more robust than 1K and doesn't yellow like 1K can.  I think I'd like to 2K clear the wheel hubs.  Concern is how well will 2K clear stick to polished aluminum...... on my '83 Magna V65, I had polished engine side covers and valve covers, and as long as they are accessible, a little spit and polish once in a while and they were fine.  I'd still like to avoid that if possible, so.... to clear or not to clear, that is the question.

Wheel hubs - I plan to get them media blasted, which will clean them all up, my guy says glass bead #13 will be a good prep for polishing, but.... I didn't really think the brake plates should be polished, and this is good news... although that rear one is kinda asking for it, lol.  My guy says dry blasting (sand?) is better to prep a surface for painting, which might help the clear stay on there, I'll see some samples when I take him some parts.....

My front master cyl seems bare aluminum with no anodizing, or who knows it may have disappeared.  Yes black anodize does fade/go purple, looks like crap then.  I'm thinkin' I'll paint it a satin gloss and maybe soft gloss and maybe semi for the triple clamp, info panel, tach/speedo and even the headlight.  I understand the headlights were gloss, but hey, let's keep some semblance of patina over the past 52 years, lol.  I think it would look more uniform even if not technically restored to original.

Forks - Seems to me I think they'd look better if same as the wheel hubs, again with 2K clear.  Polished seems a bit much as I don't know of any bikes with polished forks.  Modern bikes have silver powder coat, which is very robust.

I painted the frame with a semi-gloss as I thought gloss was too much for the 52 year old girl.... again wanting it to look a little patina-ed as it was when I got it.

I'm still open to suggestion if you think I'm crazy....... and thanks again for all the input.

Well, I dove in a bit deeper and pulled the headlight off.... cleaned it up and yep, gloss black, so I'll go that way.

I use Omni/PPG 2K clear over finished bare aluminum. I finish with a cloth wheel and wenol aluminum polish that has some grit to it. The trick is to get it super clean before applying the clear. Hot water followed by Acetone

So I got looking closer in better light today, and notice some of the nipples do indeed have some of that yellow dichromate, but fading away.  A look at the wheel hubs and the center of the front looks polished in a couple of areas, outer faces are not as shiny but appear clearcoated perhaps.  Rear hub left side is polished except for the outer diameter (a clear delineation), middle of the hub not polished (at the moment), and right brake plate looks to have been polished and clearcoated at one time.

My left side fork leg may have been polished, the right side much duller...... hmmmm.  Guess I'll just play it by ear as I get to it.... not in a hurry.

I bought me a good quality used polisher, looks like I'm doing it myself..... folks near me are shying away from doing it for me.

Be sure to use a good dust mask when sanding and polishing the aluminum parts. Protect your lungs and skin.

 During covid I got one DID rim from 4-1 and one from Z1 parts. I don't think DID sells seconds so anywhere you find them should be good to go. Right now, 4-1 only has rising sun and Z1 only has one end in stock. Z1 Ent doesn't have stock either, the supply might be short.
