Topic: Interesting K0 carb tidbit

[ekpent]

 Here is an interesting K0 carb tidbit if you were doing a perfect resto. On a sub 7,000 miles K0 I bought back in 2013 I was wondering what this green sticker was that was stuck on the side of the carb. There was also a blue one on the engine case. I think I determined back then it was an inspection sticker of some sort. When I first saw them they looked like a sticker people use at garage sales to write a price on 
 Today I was looking at some K0 carbs that are advertised in my neck of the woods and lo and behold there is that same green round sticker on those confirming to me that they were placed there at the Honda factory. So if you got a minty restored K0 you now have to find a blue and green sticker !
  First pic is my carb and last two the set for sale.I can get a picture of the blue sticker placement if anyone is interested.  Eric

Good info for a by the book restoration. I have to imagine most carbs of that era are missing that sticker nowadays. It's amazing how things like that or  paint marks that show it was inspected make a difference in restoring to factory original. I had some paint marks on my lower triple clamp bolts at one time. If I was going for show I would have to put them back on there.It seems pretty anal but that could be the difference between a first place ribbon and 2nd place.

 A friend of mine who was on the forum when restoring a K5 came down to my shop once with camera pen and pad and studied hard some of my stock bikes for yellow paint locations, color,style of the dab and other little things to incorporate into his resto. Of course it came out stunning and he has the trophies and plaques to prove it. He has had some offers on it from wealthy individuals at shows that I may have found hard to resist !

  I will check it out 69 and thanks for taking the time to post that. My bike is red but not sure on the one the carb bank came off from.

Damn! I guess stuff like wrinkle tanks and indented ignition switches is just the tip of the iceburg!! I wonder if somewhere there is a guy that's still alive that would know this stuff firsthand!

 Those people over at the Sandcast site know their stuff. I have not lurked around there for a long time but always interesting.

  I think the dots were to identify a quality control issue that needed attention, the color identified the tester or the repairman.  More than one qc repairman may have worked on a single bike with multiple repairs or adjustments. This is just my opinion and makes more sense than the paint color idea which is usually incorrect.

It doesn't make any sense that the color of the dots on the carbs would have anything to do with paint color, when engine numbers didn't even match frame numbers?? My best guess is there were two or more carb assembly lines, so if a problem showed up, the color code would point to the line with the problem.

 After reading the sandcast post it seems there was a red and blue dot used on engines but color of the bike did not seem to match the dot color in all or most cases and I believe green was the only color used on the carbs. No definitive answer was really given so still a little bit of a mystery I guess. I'll take a picture of my blue dot next time at the shop just for fun.

 I remember seeing a dot on a 750 but can't think of one on a bike I have right now.

I'm wondering why the dots were designed to be so durable. On the sandcast forum, it seems they are either painted or glued on with a strong adhesive.


If they were used during the manufacturing process as some kind of identifier, wouldn't they have been removed to indicate that whatever was needed was accomplished? Why make these markings capable of lasting almost 50 years already?

 Can't say that I have ever noticed any blue,red or green dots on any of my K1 or later bikes. Now I have to look closer. Seems to be a 1969-70 Sandcast / K0 thing.

Just 69 and 70, some did, many did not.
