It won't get ridden enough in my opinion to be a safety issue.
Boo! Hiss!

I know your reply was in fun but was that because I would start it up and ride a little or that I wouldn't ride it more than a little?

Just read this whole thread. Great work sir, and very informative

I hope to see it there this winter. There was one in a museum I looked at a couple years ago. My brother remembered I mentioned several incorrect parts on it. Not the case with your bike, Mine is really better than the one in the museum too.

Congrats Mark......that is quite an honor that hasn't been seen around here (that I know of).

The 28 carb tops are not a sandcast thing. They were actually used on VINs up to 17,342. Service Bulliten #15 was a recall on the caps, slides, springs and cables. There were issues where the cables would bind up and the throttle would not close. So the new slides and springs were longer and the new cables were bigger diameter. To answer your question, 576 would have had them until (and if) they were recalled. The only 28 tops that exist are ones that weren't thrown away for the recall, or probably more rarely missed the recall. I used the 28 tops on my restoration in an attempt to make it like it left the factory. It won't get ridden enough in my opinion to be a safety issue.

Thanks for that info!
I wondered why my 16xxx DC has "28" carbs.

And thanks for that wonderful thread with so many great info!

I ordered a personalized license plate for 97 about 12 weeks ago. It was only supposed to take 8 weeks to get it but I finally got it. I don’t know about other states but Minnesota doesn’t stamp them anymore, they print them. I don’t think they look as good but it still makes a nice finishing touch. I’m sending to the museum and they will put it on for me.

Very nice touch Mark!...Larry

Several states now have the non-stamped plates. They almost look fake or easy to counterfeit. It's probably the wave of the future along with the bar code at the bottom. I DO like your plate number!

Now that I have some time I will try to catch up on my posts. The #97 carbs have different vents than the later carbs. Here is a pic with the #97 carb on the left with a straight vent tube.

Here’s a closer view of the straight tube. I suspect this feature is quite rare.

Here is the typical angled tube for comparison.

The T-joint between the 1-2 and 2-3 carbs is different too. The early version with the shorter cross tube is on the left.

Although not really a sandcast thing, I decided to use “28” carb parts for a restoration more accurate to leaving the factory. They were replaced in a recall as described in Honda Service Bulletin #15.

As (most of) you all know, this feature is identified with the number 28 embossed on the carb tops as shown on the left. Also note that the cable adjuster is much smaller (as well as the rubber cap) for a 5mm diameter cable instead of the 6mm diameter replacement.

The tops are thinner and had a gasket. Maybe someone can chime in on this but I don’t think the gaskets are used on later carbs. At least I’ve had some sets that didn’t have them.

The caps are also thinner…

…and the slides are shorter. The “28” slides are 41mm long and the later slides are 46mm long.

And the springs are shorter. I had a couple of sets of “28” carbs but was missing a couple of springs. I had some made up to exactly match the originals. Here are specs.
Material: stainless steel spring wire
Wire diameter, .9mm (.035”)
Free length, 128mm
Outside diameter, 18.5mm
Active coils, 15 ½
Total coils, 13 ½
Closed ends
Load @ 55mm = 1.15 lb.

I had the carbs rebuilt by hondaman and bought some excellent reproduction 5mm throttle cables. At least for now when I twist the throttle and let go it snaps right back. I think they will be just fine.

it will take someone like rain man to remember all these minute details.

markb · « **Reply #736 on:** December 01, 2015, 03:11:24 PM »

That's one of the reasons I post. Then I know where to find them when I can't remember.

I have some pictures of #97 on display at the Petersen Museum. Sam (ujeni) sent me a link for a blog he saw about the re-opening and the motorcycle display. Here it is if you want to check it out.
http://www.bike-urious.com/the-petersen-museum-is-back/

These first three pictures are from the blog.

They are in chronological order from newest in the back to oldest in the front.

Everyone knows the red sandcasts are fastest and displayed going downhill makes it look even faster.

The rest of the pictures are from the guy who originally called me and doesn’t work there anymore but happened to be there for the re-opening.

She’s in pretty nice company. There is a lot of red around. A blue/green one would have looked nice too.

Here you can see a Triumph Bonneville to the right and there is a Vincent Black Shadow that you can’t see ahead of the Triumph, a couple of my favorite non-Japanese bikes.

I think that’s a couple of Harleys in front and there is a Kawasaki and Ducati behind.

Here are a couple of close-ups.

I like this shot.

I’m really looking forward to going to see it.

We do a fly and ride to CA almost every year. This will be a must do stop this year. Once again, absolutely great job, and congrats on being in this museum.

Can't wait to visit the new Petersen and see your bike. Congrats! She looks terrific!

Beautiful!

Congrats, thats quite an honor.

How long will your bike be there?

markb · « **Reply #742 on:** December 14, 2015, 05:38:57 AM »

Thanks for all the nice comments guys. It will be there for a year.

Sgt.Pinback · « **Reply #743 on:** December 14, 2015, 08:38:49 AM »

You can be proud and the museum happy!

markb · « **Reply #744 on:** December 16, 2015, 07:34:35 AM »

The Petersen Museum sent me a bunch of photos of their displays. Not just the bikes but everything. Pretty amazing. This one is my favorite of #97.

Roach Carver · « **Reply #745 on:** December 17, 2015, 06:33:03 AM »

That is beautiful. I remember what it looked like in the beginning. Quite a feat.

Mark,

Admittedly I shook my head more than once at your insistent attention to detail on what I consider trivial things. After all lots of these things are usually covered up anyway and no one would be the wiser except for you while tooling down the road. However I get it. This is a special bike and who knows, maybe I would've done the same thing were it mine...on second thought probably not LOL. Kudos to your determination getting this done.
By the way, how did the Peterson get wind of your bike anyway?

markb · « **Reply #747 on:** December 17, 2015, 02:24:38 PM »

Thanks guys.
One of the curators saw one of my threads, either this thread or probably the similar one on the SOOC site (I can't remember) and contacted me. There are plenty of worthy bikes around so I feel lucky to have even been considered.

HondaMan · « **Reply #748 on:** December 17, 2015, 04:55:35 PM »

I just dropped by for some Christmas inspiration, and danged if I didn't get it here!
Great job, Mark! It reminds me of the sandcast I didn't get in 1969, because the shop owner sold it (when it came in, was supposed to be for me...) to his brother-in-law instead. It was a red one. But, now I feel better, knowing his sure doesn't look like yours!
